Our take on the NAD C 356DAC

Adding a DAC to an acclaimed integrated amp is like taking a slice of warm pie and adding a scoop of vanilla. The point is, it's rare that something couldn't be bettered by adding a complementary item. And NAD has pushed this time-honored philosophy forward into the digital age with the new C 356DAC integrated amplifier.

An integrated amp for your whole music library

Adding a DAC to an acclaimed integrated amp is like taking a slice of warm pie and adding a scoop of vanilla. The point is, it's rare that something couldn't be bettered by adding a complementary item. And NAD has pushed this time-honored philosophy forward into the digital age with the new C 356DAC integrated amplifier.

They've taken one of their popular mainstays, the C 356BEE integrated amp, and added a world-class DAC so that you can treat all your digital sources to the power and control that has made NAD legendary among audio enthusiasts.

The MDC (Modular Design Construction) DAC module

The MDC (Modular Design Construction) DAC module, which comes installed

Digital sources welcome

This amp features NAD's innovative modular design construction,which allows you to customize your input configuration by adding or swapping modules on the back of the unit. The 356DAC's included DAC module features an asynchronous USB connection that controls the data flow of your computer audio files, reclocking the data stream to minimize jitter. Your music will come to life in three dimensions as the soundstage expands and reveals detail. This module also features an optical input, for use with your CD, DVD, or Blu-ray player, and it supports sample rates of up to 192kHz.

Power to spare

NAD's PowerDrive™ technology allows the C 356DAC to sound even more potent than you would expect from its rating of 80 watts x 2 channels. Like a turbo-charger, the PowerDrive circuitry senses the demands placed on the amp and pours on higher current when it's needed to reproduce peaks of musical energy.

The ins and outs

With enough connections to hook up seven audio components and two pairs of speakers, the C 356DAC can handle your arsenal of audio gear. Should you wish to swap out the DAC module to accommodate a turntable, owners can install an optional NAD PP375 phono input module for listening to vinyl. The included remote gives you easy control of the amplifier and the other NAD audio components in your system.

Separate preamp input/line-level output jacks let you use the C 355DAC as an independent power amplifier (or as a preamp, in the unlikely event that the built-in wattage doesn't produce enough volume for you). If your main stereo speakers don't supply enough bass to disturb the peace, you can easily add a powered subwoofer.

And it's green too

NAD designed the C 356DAC to reduce energy consumption without sacrificing performance. It consumes just 0.5 watts in standby mode and includes a convenient all-off "vacation" switch.

Crutchfield Customer Review (What's this?)

This integrated amp is everything I could ask for. I don't care for the latest bells and whistles, I'm interested in an extremely well built product. The NAD satisfies. Excellent sound and Crutchfield is great. Why else would I make my purchase from Montana!

Pros: Great sound; great construction.

Cons: Absolutely none

Amp with some power

JohnG from Michigan on 1/14/2016

Crutchfield Customer Review (What's this?)

I was looking for an amp that provided good clean sound with some real power. I found the home theater receivers to be good for movies, but they did not have what it takes for good sounding music. This amp is clean, and provides plenty of bass, and all around great sound. This is the best sounding amplifier I have ever owned. I purchased an Audioengine B1 for the bluetooth connection. Spotify set on high quality sounds incredible running my Klipsch RB-61-II bookshelf speakers. The amp seems under rated at 80 watts / channel.

Pros: Excellent amplifier, one of the best I have heard.

Cons: Non so far.


Nick from North Carolina on 1/12/2016

Crutchfield Customer Review (What's this?)

I purchased the NDA C356DAC to replace an older NAD 720BEE Stereo Receiver that formed the basis of my home audio system. Unfortunately the 720 died following an electric storm, yes I shoule have used an isolating power bar (an expensive lesson), and my ancient NDA 3020A Stereo Amp that has given me 30+ years of excellent service. The sound quality from the C356DAC lives up to NAD's reputation. The 80W gives more than enough power to drive multiple the speaker pairs throughout my home.. Our primary speakers (A) are KEF XQ's, and a KEF KUBE-2 subwoofer. with a variety of other speakers throughout the house all connected via the B output and a six pair distribution switch. To make the most of digital music the MDC DAC is connected to an Apple Airport express hub allowing apple airplay connections to iPad. iPhone's, PCs, etc. I considered going all digital, but wanted to retain the ability to pay CDs from my older NDA C515BEE CD player, and very old NAD tape player. the C356BEE DAC allows me to play both digital and analogue sources. This is my 4th NAD Amp/Reciever, the sound quality is fantastic, and the reliability second to none - assumeing you isolate them from storms!

Pros: Great unit allows both analogue and digital inputs so you can still use some of your older technology. Strong high performance sound!

Cons: None that I can identify


Don from Sacramento, California on 12/27/2015

Crutchfield Customer Review (What's this?)

I've only owned two previous systems, both were mid range Sony products with Polk speakers. Those systems served me well for many years without a hitch. After reading many positive reviews of NAD products, I decided to give them a try. I connected the NAD 356DAC to a NAD 546BEE via an optical cable and paired them with B & W 685 S2 speakers and a B & W ASW610 subwoofer. The sound, in a word, was nothing short of spectacular throughout the full range, in every genre and at any volume. Rock solid all the way.

Pros: Looks, feels and sounds like quality. Simple design and free of the rows of glitzy useless buttons found on some other brands.

Cons: Not really a con but a caution. If you play a poor quality recording, the NAD is going to reproduce the flaws with the same vigor and clarity that it does with the good stuff.

A Nearly Perfect Budget Intergrated Amp

Beejer50 from Illinois on 12/21/2015

Crutchfield Customer Review (What's this?)

Was considering some other integrated amps at this price point (Cambridge, Peachtree), and have not regretted my choice. 80 wrms per side is an understatement. It is loud. This amp has plenty of punchy midrange, yet maintains air in the high end. Nice separation and 3D image. I use a sub for low end. Very articulate and accurate reproduction from digital sources. My paired NAD 546BEE CD Player sounds amazing using an optical cable to the DAC module built into the amp. It also has a set of Pre-outs (for the sub) AND Pre/Main inputs and outputs for an equalizer or another amp. There are plenty of RCA analogue inputs. I do not use the "soft clipping" feature. Would have received 5 stars if it had an s/pdif coaxial input in the DAC module. As it is, the choice is optical or usb, A usb input on the front would have also been nice, but it does have a 3.5mm input on the front panel. Does not have a phono pre-amp, so if you have vinyl, you may need an external one. I would recommend this integrated amp to anyone wishing to drop less than $1000 on a fine product.



Excellent Amp!

Randy from North Carolina on 7/20/2015

Crutchfield Customer Review (What's this?)

After owning an NAD 7100 for several years, I knew the reliability of the product, so that wasn't a question. I just didn't know about the DAC and was a bit concerned about the negative statements about it being on the back of the unit. Turns out that's not a problem, very easy to access from the front and moving from DAC to Optical. I'm powering B&W's and the sound is full, open and pleasing. Listened to a lossless download through the DAC, WOW! So glad I stuck with NAD.

Pros: Plenty of power, even when pushed Set up was a breeze Good clean looks

Cons: Nothing yet...

Stop thinking and buy the 356!!!!

Joe from California on 7/18/2015

Crutchfield Customer Review (What's this?)

I absolutely love this amp/dac!!! I found my old preamp/DAC too crunchy/bright and the bottom end was lacking. I could have just gotten a new DAC/Preamp, but I wanted a simple, all-in-one piece opposed to separates. I was looking at the Yamaha 801, this 356BEE, and peachtree, with a budget under 1000. I was torn on the yamaha because there are quite a few mixed reviews out there about it and I really like the old Yamaha amps in vintage stores. While the 801 has tons of power and more digital inputs, it lacks pre-outs. So, I worked with Abe at Crutchfield, and he steered me correctly. Supposedly, NAD rates their power using a larger bandwidth, so the numbers may be smaller on spec, but the sound is big in application!!! I haven't had to take it much above 10 o'clock on the volume to fill a 5000 cubic foot room with speakers rated at 89 db on the sensitivity and 4 ohm. Another high end feature is the soft-clipping and while some may hate clipping, it is a feature I like and use to ultimately keep distortion extremely low while protecting circuitry. Read the other site reviews out there on the 356 if you're still torn then read for a little history and insight on NAD. To the DAC specifically: I am not the biggest fan of the Burr-Brown chip, but NAD's MDC design combined with a proper preamplifier circuitry make it a fine DAC that will more than satisfy those of you using the highest resolution audio.

Pros: Sound, dynamics (well designed to deliver high current loads when needed), clean simple appearance with cool blue lights, soft clipping, and lastly tone controls that make only subtle adjustments when needed (great at lower volumes to compensate for human hearing).

Cons: The DAC is in the back and I am pretty much limited to using only the optical input with my furniture and thats minor if you really only need one digital input - I have appleTV and cable so my TV functions as the receiver and outputs one digital audio line.

Sneaky Good!

CE from North Carolina on 6/24/2015

Crutchfield Customer Review (What's this?)

Outstanding amp. Freaking love it.

Pros: Lots of power, tight design, simple construction.

Cons: Would like another DAC in the module, and deep-six the USB.

Great Power

Collin from California on 6/23/2015

Crutchfield Customer Review (What's this?)

i had an old NAD stereo amp from the late 80's i got from my father, it was only rated at 25W, but it packed a punch! Great quality and sound for being old, so i decided to stay within the NAD family when looking for my next stereo amp. i went with the 356DAC because i would be running floor standing speakers in a medium size room. i paired the amp with some Klipsch RF 82ii and its sounds really good! i listen to hip-hop, house, rap, jazz, rock, and everything sounds great!

Pros: great power, simple

Cons: not the best looking receiver, DAC switch (choose between: USB, optical, phono) is in the back of the reciever

Awesome sound

bjohn from Wisconsin on 6/5/2015

Crutchfield Customer Review (What's this?)

My initial stereo system purchased in 1973 included a Sansui receiver. The shop I took it to for servicing asked me to listen the NAD products and I was blown away with the quality of the sound. My new NAD is awesome.

Pros: great sound

Cons: Had to buy a separate phonograph amp for my records.

Dr. V from Midland , MI on 3/1/2015

Crutchfield Customer Review (What's this?)

Smooth sounding and powerful. I was looking for a high end integrated amp to listen to music, and this unit delivered. Already have an old school Harman Kardon that I use for home theatre and does a great job.

Pros: Powerful , sounds great. The DAC sounds great. Big difference compared to my Tascam CD player's pretty good digital converter. Really great on HI FI ( CD quality) sound from TIDAL and even better with higher def downloads). Wanted an integrated amp that can eventually handle Magnepan speakers ( when I finally save up the cash ) , but for now my bookshelves are sounding great. The remote was a welcome bonus.

Cons: The soft clipping switch looks recessed and almost defective. Only one USB input on the DAC. Only one optical input on the DAC. The button to switch between USB and optical inputs is in the back so the unit has to be on top of a table ( if you are using both inputs from the DAC). No subwoofer out. These negatives are small and insignificant compared to the sound quality and value of the unit.

Just what the doctor ordered

Clark K from Ohio on 1/31/2015

Crutchfield Customer Review (What's this?)

I agree with the other 5-star ratings. This int amp sounds great with plenty of oomph, tight bass, and a lovely sound stage. I listen to classical music and hear some details never heard on my old amp/preamp, especially on mono or early stereo recordings. The only sour note I have, The only minor quibble I have is that is that if you select MDC, the Disc input is lost. No big deal. Paired with Klipsch RB 81s.



Hear each instrument clearly

EB from Northeast US on 9/13/2014

Crutchfield Customer Review (What's this?)

Although I am not a technical expert in the science and specifications of sound, I like to hear all of the instruments clearly. When I switched to this amp (from an old Aiwa), I started hearing all of the music for the first time. I hear sounds in songs that I had not known, or barely known, were there. Before, for so many years, music was just one sound made up of some of the parts all mixed up together. Now, that mixture has become whole and complete and rich. At the same time, I can hear each part, each separate part, of that complete whole. I can hear what the music really sounds like. I can hear the music for the first time. Good speakers are necessary too. I'm using either old Bose 301 Series III speakers, or Grado Lab SR 225 headphones. The amp is plugged into my lower-end desktop PC, where the music comes from CD's, Windows Media Player Library, or from YouTube. The only change to my system is the amp. If I had to choose between upgrading my amp or speakers first, I would talk to a Crutchfield advisor, and then think before deciding.

Pros: My favorite music is even better with this amp. I probably won't ever buy another amp for my home system (less spending in the long run).

Cons: None

best sound I've ever heard

lucas from Groves, Tx on 8/3/2014

I am new to high end home audio equipment in general. Having said that, this amp and DAC provide an amazing listening experience for all kinds of music. I'm listening to it right now like I have been most of my free time since I got it and I still can't believe the detail and warmth coming from my speakers "PSB image B4" the lowest model of PSB book shelf speakers, I don't know how much the speakers are contributing to the sound being so great but regardless it is amazing. I am streaming from a sonos to the built in DAC via optical cable and it sounds like I'm listening to a CD from a quality CD player. I am streaming 24/48 from the sonos to the DAC so that helps. In my opinion you can not possible go wrong with this unit for under $1000. I got it for just over 700 as an open box item, "thanks Crutchfield".

Pros: Very detailed, warm at all volumes amazing sound from DAC with sonos and I'm sure with any component.

Cons: Yet to find any

Very flat sound... defective perhaps?

RJ from Michigan on 7/14/2014

Crutchfield Customer Review (What's this?)

I've had Harmon Kardon, Yamaha, Nackamichi, Kenwood, and Sansui.. old and new. I thought I would go bigger dollars to get better sound so I bought the NAD 356 DAC. Terrible! Very flat. Very little bass. Speakers used while testing were Wharfedale Diamond 10.2's, Paradigm V3's, and Bowers & Wilkins 500 series. My teenage son put it best "It sounds like an ipad speaker". I think I may have gotten a defective unit? I'm giving 3 stars since I'm hoping it was defective, and from what I read, NAD's shouldn't be defective. Otherwise I would have given 1 star if this truly is how this unit sounds. I sent the NAD back (Crutchfield is AWESOME) and went very basic and bought a Yamaha R-S200. It blows the NAD away and was less money.



Buy this amp

Michael R from Metter, GA on 7/11/2014

Crutchfield Customer Review (What's this?)

Absolutely fantastic amp

Pros: The DAC is a wonderful addition. This amp has plenty of power for just about any speakers - the sound is clear - typical NAD quality.

Cons: None

exceptional sound, NAD quality

MarkB from Colorado on 1/7/2014

Crutchfield Customer Review (What's this?)

Ample power to drive Bowers and Wilkins CM8 stereo speakers (A ) and Bose outdoor stereo speakers(B). Clean, musical, dynamic amp for a variety of music styles: Miles, Metheny, Bill Evans, Perahia's Mozart Piano Concertos, chamber music, Grateful Dead, Led Zeppelin, Peter Gabriel, ECM artists, blues, world... DAC has exceptional performance with HD music files, SACD, and standard 16 bit CDs Connections: 24/96 music. Connections: files from Western Digital Passport portable USB hard drive > USB port of Samsung BD-F7500 Blu-Ray > unprocessed PCM through optical cable> modular DAC in the NAD C 356DAC.

Pros: Refined performance, rugged construction, pre-installed DAC module gives immaculate detail to HD audio tracks and standard CDs, drives demanding speakers with ease.

Cons: Considering all of the pros, there really are no cons to speak of. I wish the remote's volume control was a bit more refined (a tap "up" raises the volume substantially, so you end up turning using the physical volume knob when you want slight changes in volume), but that is hardly a big problem.

Clear Power

Monkman from Middletown, CT on 12/1/2013

Crutchfield Customer Review (What's this?)

The young Johann S. Bach was often hired to test pipe organs to see if they did what their builders advertised. He would pull out all the stops and go to it; organ makers often turned pale watching him. So it was a pleasure to listen to the recording of a Bach organ recital on a system driven by the NAD C 356DAC, using a Marantz CD5004 CD player and Monitor Audio Silver 6 (the new series). After turning up the volume to about 10 o'clock, the sound was both immense and amazingly clear. The myriad tones of the organ were distinctly audible, and although I rarely listen to organ music (with the occasional exception of Joey DeFrancesco, Herbie Hancock, Dr. Lonny Smith, etc.) this was enough to make me want to hear more. The bass was astoundingly limpid and full, the mid and high ranges round and detailed. I know little about music systems, but wanted one that would run simply and reproduce the music as clearly as possible. Having listened so far to a range of orchestral and chamber music reaching from Bach, Mozart, Beethoven, Brahms, Crumb, and Ligeti to jazz by Miles Davis, Thelonious Monk, John Coltrane, Paul Chambers, and Bill Frissell, I am completely pleased with the ability of this system to allow me to hear music as though for the first time. CDs are distinctly clearer than the digital reproduction (although I've not downloaded hi-definition audio files), but the digital system makes a receiver superfluous. Service, moreover, was excellent. Bravo, Crutchfield!

Pros: Great clarity, sufficient power to drive quality tower speakers, ease of operation.

Cons: None that I've discovered so far.


mdog from Kansas City on 11/9/2013

Crutchfield Customer Review (What's this?)

Awesome amp! I trust NAD. I've had them before and they are real work-horses. I feel that they deliver the real power that they advertise vs. some of the other brands. The other NAD amp is flawless and working after 7 years but I have it in a different location. I wanted the cleaness and power of the 356 and I feel like that is what I got. For the money, I don't think you can buy a better amplifier.

Pros: Power, Reliability

Cons: None

Wanted to upgrade my Sony

Mike from Yuma, AZ on 8/21/2013

Crutchfield Customer Review (What's this?)

I ordered this amp after a lot of research to replace my older Sony amp and power my Polk RTI A7 speakers. It was extremely well made and powerful and had no distortion when cranked up. Unfortunately, I just didn't care for the sound of it compared to my Sony. It put out way more mid range than I was used to and the bass/treble controls didn't allow for much adjustment of the sound. I listened to it for several days and ultimately decided to send it back and keep my Sony. Crutchfield's return policy is awesome. Absolutely no issues with returning it.

Pros: Powerful, no distortion, well made

Cons: Not much ability to adjust the sound to your preference, too much mid range with my speaker set up

Nice upgrade from NAD C740 Receiver

DavidT from Philadelphia, PA on 1/30/2013

Crutchfield Customer Review (What's this?)

Have been listening to this for the last few weeks, and have to say, it sounds lovely. I'm not too good with reviews, but seeing as there is not much out there on this particular unit, I thought I would share some impressions. My setup is: Vortexbox [FLAC] -> Ethernet -> Squeezebox Touch -> Monster MC400DFO -> NAD C356DAC -> 14G Copper Wire -> PSB Image 2B Previously, I was running the SB Touch with an NAD C740 receiver. I started experiencing intermittent distortion in one of the channels and was able to identify the receiver as the culprit. The C356DAC appeared to be a worthy replacement/upgrade. In addition, I had been curious about stand-alone DACs, as I had heard conflicting reports regarding the quality of SB Touch DAC. With that in mind the C356DAC was a logical choice for my budget. The C356 drives the PSB speakers effortlessly - no surprises there. I am able to connect the SB Touch via both analog (RCA) and digital (SPDIF) simultaneously. This may not be technically correct, but it allows me to compare the SB Touch DAC to the NAD modular DAC by switching the inputs. Granted, the signal from the modular DAC sounds a little louder to my ears, but at the same time, it also sounds richer and fuller. The SB Touch DAC, by comparison, sounds rather flat and lifeless. One quirk I have noticed is that it takes a minute or two for the NAD to "find" the digital signal from the SB Touch. This is manifest as having a signal in only one channel.

Pros: Simple, solid, and so far reliable. Typically NAD. Modular DAC - potential for upgrades? Stereo minijack input on front panel for connecting MP3 player or similar.

Cons: Not sure if it is NAD or the Squeezebox Touch, but it takes a minute or two to get a signal in both channels. After the connection if "made", it is smooth sailing.

NAD C 356BEE DAC Review

Dom from Los Angeles, CA on 12/12/2012

Crutchfield Customer Review (What's this?)

So I have had this amplifier for about 3 weeks now and WOW, I really didnt think that just changing an amp would make such a HUGE difference in my system! I use the AudioQuest cinnamon USB cable to connect my Mac to the built in DAC, this has given me such amazing improvements in clarity and imagingIt sounds ALOT more powerful than i would imagine from an 80 watt, My other amp was 120 watt, but this is way louder and effortless, like i barely have to turn the power up 1/4 of the way and its LOUD. Its VERY clear and precise and has a very quiet/black background. no hissing or humming even if u crank it up!... I cannot believe what a good deal this amp is, I got it as an open box item, so it was a great price! and it literally sounds like i have gotten a new pair of speakers! I'm floored.

Pros: Very powerful, much more than would seem from the 80 wtts/channel, EASILY beats out my old 150 watt sony! Such clear music Very dynamic, i can hear very fine details in songs that i never had before, AND very good imaging, i can almost see where each instrument is playing and feel as through thwy are there. I like them with Jazz and instrumental but even Trance/ progressive and HT sound good! They are very versatile! Very sturdy remote

Cons: kind of annoying the USB input is on the back, kind of wish there was one in the front, but that's just me. and it could be a little more attractive or have a screen, but its still has a very nice polished and classic look.

Product Research



NAD PowerDrive Circuit: The C 356DAC use NAD's proprietary PowerDrive amplifier technology that provides high dynamic power and low impedance drive capability. By adding a second high-voltage rail to the amp's well regulated high-current power supply, the amplifier can nearly double its continuous power on a short term dynamic power basis. This uniquely efficient power supply topology provides the real world benefits of high dynamic power that remains uncompromised by low impedance speakers.

FDP Specifications: NAD uses Full Disclosure Power (FDP), the most demanding criterion for performance measurement. FDP specifies distortion under the most extreme conditions of low impedance loads and frequency extremes, rather than the simple and easy 1kHz @ 8 ohms test quoted by many of other manufactures. NAD uses this stricter performance criterion because it more closely matches the demands of real music and real loudspeakers. Maintaining specified distortion at 4 ohms and at 20Hz to 20kHz is a much more difficult achievement. The NAD C 356DAC is rated at 80 watts x 2 channel (@ 20-20kHz, in 4/8-ohm, with 0.007% THD).

Soft Clipping: NAD's Soft Clipping circuit gently limits the output of the C 356DAC to minimize audible distortion when the amplifier is over-driven. While Soft Clipping can be left on at all times to reduce the likelihood of audible distortion from excessive volume settings, you can also turn the circuit off for critical listening if you prefer.

Digital-to-Analog Converter (DAC): The C 356DAC stereo integrated amplifier is fitted with NAD's MDC DAC USB Digital-to-Analog Converter which lets you listen to music stored on or streamed to your computer through your hifi-system without noise or distortion. The C 356DAC uses an 'asynchronous USB' technique and a high precision clock, so your 24-bit/96kHz quality computer music flows smoothly without 'jitter' or harsh distortion.

Modular Design Construction (MDC): Modular Design Construction (MDC) makes future upgrades possible with interchangeable, upgradeable modules.


Remote Control: The included IR remote control handles the key functions of the C 356DAC. The IR remote can also be used to directly command other NAD products that respond to applicable common remote control codes. This includes other NAD Stereo Receiver, Integrated Amplifier, and Preamplifier models. It has additional controls to remotely operate NAD CD Players, AM/FM Tuners, and dedicated AM/FM/DB Tuners. It will operate up to a distance of 23'. The remote requires two "AA" alkaline batteries (included).

Volume: The Volume control adjust the overall loudness of the signals being fed to t he loudspeakers or headphones. The Volume control does not affect recordings made using the Tape output terminals, but will affect the signal going to the Pre-amp output terminals (Pre Out 1 and Pre Out 2).

Balance: The Balance control adjusts the relative levels of the left and right speakers. The Balance control does not affect recordings made using the Tape output terminals, but will affect the signal going to the Pre-amp output terminals (Pre Out 1 and Pre Out 2).

Tone Controls: The C 356DAC stereo integrated amplifier features independent Bass (100Hz) & Treble (10kHz) controls to adjust the tonal balanced of your system. The Tone control does not affect recordings made using the Tape output terminals, but will affect the signal going to the Pre-amp output terminals (Pre Out 1 and Pre Out 2).

Note: The Tone control circuits can be bypassed.
