Niles SI-2150

This is the perfect stereo amp to add 2 rear ceiling speakers in my theater. It has a very low profile which fits nicely on a shelf. Temperature never got above mildly warm

So far a clean sounding amp. I could ding it on the slow start and power on button always being lit up on sensing mode. Never had a class D amp before and this fit the price and power requirements.

Killer Amp

Hi, I purchased this to provide power to my JBL A190 speakers. Wow!!! amazing. The amp puts out 150 watts @8ohms per channel. The jbl speakers are 6 ohm, so I'm getting about 200 watts per channel from this amp. I couldn't be happier with my system. Apple TV 4k, 2 Jbl A-190 floor standing speakers, Yamaha RX-V6A, Bose Acoustimass 15ii driven from the yamaha RX-V6A, Klipsch R120sw 200 watt RMS sub and the Niles SL-1250 driving the front 2 Jbl A-190. I created a killer Atmos system with the Bose satellite cubes using 2 of them as front presence speakers. I'm telling you it is amazing. Buy the Niles....you will not be disappointed.

The Strong Silent Type

I have installed the Niles in my system to power the Bose 901 Series 6s that I use as main speakers with my Yamaha RX-V685 receiver . The sound is phenomenal. Well detailed with an expansive yet spatially accurate sound stage and plenty of power to meet the needs of any transients . Very quiet at rest too. I've had it just a short time but so far I am very happy and impressed with the purchase. A top performer at a good price.

Happy with purchase

This review may be moot since it appears Crutchfield has discontinued the model, but I'll leave it anyway. I was looking for an amp to drive 12 pairs of speakers for a whole house audio system that uses a Russound pro12 speaker selector and Russound volume controls (in bypass mode). I was previously trying to use Zone 2 on my Yamaha TSR-7850 and it would shut off under moderate to high volume levels. An older Sony stereo receiver I had would do the same thing. Most of the time it was fine for the house, but I specifically wanted to be able to make the outdoor speakers by the pool louder. I found this model on my own looking for something that could do 150w RMS @ 8ohms, but took advantage of Crutchfield's great pre-sales support and talked to Clarence for 15-20 minutes confirming my assumptions and listening to his opinions. So far so good - this is a well-built amp and it's holding up just fine. It was worth the money to no longer live with the frustrations I was dealing with. You get what you pay for!

Bought this to replace a Niles SI-250 that had lost one channel. Upgraded to the SI-2150 for more power to drive 6 sets of speakers via my speaker selector switch. Love the low profile of this Niles amp series and that the SI-2150 was the exact same size as my old one.

Niles SI-2150

It was suggested by someone other than Crutchfield that I purchase a different amp. I chose to purchase the Niles SI-2150 because of its weight due due a glass shelf weight restriction. This option was suggested by Crutchfield. In my case, this amp has the power but took the life out of the B&W 703 speakers it was driving. After about 3 weeks one of the channels quit working. I returned the amp to Crutchfield with absolutely no problem. I replaced it with a Marantz MM7025 that i bought from Crutchfield. It has just arrived today and has not yet been installed. Crutchfield has been very accommodating, easy to work with and there have been zero hassles. Customer service from Crutchfield is amazing and you have to experience it to believe it.

Very smooth power. Provides the overhead needed for my front speakers on my Atmos 7.1.4 system and made my system come to life.. (When you add 4 more Atmos speakers, it strains the power of even a very powerful Yamaha RX-A3080 - 150 watts RMS/Ch.) Runs very cool.

Love this Niles SI-2150 my home theater has new life now

This amp really brought my Polk Rti A5 fronts to new life. The sound from Blu-ray movies are now super huge and very clear. I am connecting to a Yamaha RX-A1060 receiver. Crutchfield sales support is always the best. They recommended a different brand with similar specs but cheaper, I went with Niles because it looks more slicker and Niles support seems very approachable. Before I bought the amp, I emailed Niles with couple of technical specs question and they responded promptly. I love the amp. The rear volume controls are very useful. I have turned them almost all the way up. Sounds awesome. Crutchfield was so kind enough give me a price difference refund when the price dropped 10 days after I bought the amp. All my new AV gear purchases will be from Crutchfield only :)

Great Amp -excellent design & build quality.

Very pleased/. Feels well designed / made. Crutchfield staff originally suggested a less expensive option but this was a better fit for my purpose. They were being conservative and anything but over selling. Tech support has been excellent.

Good value in a small footprint

I needed something small yet powerful to drive a pair of Def. Tech speakers in my living room in conjunction with using a Sonus reciever. This seemed to do the trick. Given it was on sale it was a very economical purchase.

Niles SI-2150 power amp

After my beloved pioneer spec 4 left channel went out and wasn't able to get it repaired I needed to replaced with something that was able to drive a par of 4 ohm subwoofers and after a lot of research it seemed the Nlies SI-2150 was the best match. After being in use for a week or so I am happy with performance. Its be able to handle job very will with on issues so far. The online chat with Abe before purchase was very helpful. Thanks again Crutchfield !!!

Powering Extra Speakers

I purchased this Amp to run three sets of speakers in different rooms. Working with a Denon AVR X2100W receiver and a Niles selector switch I can now listen to TV sound, music and tuner audio in two inside rooms and out on the patio. The Amp works as advertised sending clear sound signals where we want them.

Powers 10 Speakers in 6 Rooms

I bought this to power 10 ceiling speakers in 6 rooms (4 stereo, 2 mono). I connected it to the Zone 3 output of my Onkyo TX-NR737. It senses when there is audio output from the receiver and automatically turns on and off. The sound in very clear. The amp has plenty of power for my configuration. I only needed to set the volume controls at 1/3 of maximum power. This is plenty loud and we usually turn the volume down using the volume controls in each room.

First one failed but Crutchfield came to the rescue!

Using the amp to bi-amp my Polk RTi A9 Floorstanding Loudspeakers. Within the first three weeks the amp failed. I called Crutchfield and performed all of the useful troubleshooting steps that the Tech Support staff offered. Crutchfield sent out a new replacement once it was determined the issue was the amp. I can't say enough about the customer service I have received from Crutchfield, it makes a huge impact on all of my future home audio purchases.

TOTAL WASTE OF MONEY

turned out defective and then incompatible with my Marantz SR5007, I was talked into buying it by the staff, never even heard of the brand, not sure why it was even an option for the tech support, so there, I guess do your homework, and don't think Crutchfield will know exactly if its compatible with a ZONE 2 receiver output

Great amp

Great amp, lots of power. Hooked up to a connector block and volume control for 4 sets of speakers in multiple rooms. Plenty of power/volume with output levels set to about 30%. Auto on music sensing feature is very nice.
