200 Watts of Quality Power easily drives 6 Niles OS 5.5 speakers

This Power Amp was recommended by the AV Design Experts and I am very pleased with it performance. I was concerned it wouldn't have enough power to drive 6 Niles OS 5.5 speakers in a outdoor pavilion through a volume controlled speaker selector. It has absolutely no issue driving all 6 speakers at the same time and they sound great. You get what you pay for, so although this amp is a little pricey I believe you will be very happy with the performance. Due to being in an outdoor space I want to go minimal with speakers, amp, and Bluetooth receiver. This amp matched with the Niles outdoor speakers, and iFi Audio Zen Blue is a great combo.

Great Sound and Budget Friendly

I was looking for an amp to pair with my Carver Pre-Amp that was budget friendly and would fit in my stereo cabinet. This amp was perfect. Nice, compact size and paired well with my Carver. Using the amp to power my Polk Tsi-300 and it does a great job. My previous amp was an older Technics amp and I was worried that a newer amp would not sound as good but was very pleasantly surprised. I also like that the amp runs cool even at high volumes for long listening sessions. Lots of power for a great price.

Front height speakers

It is a great product and got it at a super sale price at Crutchfield. I purchased it to power my front height speakers paired with a Sony STR-ZA2100ES and it is a good match and integrated perfectly. I do think that my STR-ZA2100ES treble is more airy and refined than on this unit although it is still breaking in and being rated at the same wattage per channel I also believe the Sony is more dynamic and a bit more power but it could be because it is powering the fronts center, surround and surround speakers. Still a great until at a great price, would not change it for another amplifier.

Niles SI-2100 as Dolby Atmos Front Height power amp

I purchased the SI-2100 to power my front height speakers in my 7.1.2 Dolby Atmos setup, driving the SI-2100 from my Anthem MRX-720 receiver. The SI-2100 was easy to add to the system, I used the trigger output of the MRX-720 to trigger the SI-2100 to power on with the rest of the system. The amp is very quiet, no hiss or noise with my ear right against the height speakers.

Solid little amp

I bought two of these to run 4 outdoor NHT O2 ARC (8ohm) speakers that are installed on dedicated fence posts around my pool. Both amps are daisy chained and hanging off of a Marantz NR1506 inside my house. Unfortunately, this makes my speaker wire runs a little long (all >60ft) so I ended up buying two of these amps and running a single speaker (8ohm) off of each channel using 12awg wire. I'm using banana plugs at all connections. NOTE: If I had the ability to do shorter speaker wire runs I would have no problem running a single SI-2100 to power four 8ohm speakers I use these amps almost daily. I've even used them for ~12 hours straight w/o issue. This includes cranking things up and down throughout the day/night. Considering how low profile they are, they don't get very hot. However, if you plan to stack these with other equipment, I suggest placing this amp on top, or making sure to add some space between each device. The only area for heat dissipation is on top of the amp. So far, I'm impressed. They deliver a decent amount of power for the money in a no frills package. If you already have a frontend device (receiver/wifi streaming device), these amps will make a nice addition to your setup.

Literal Tears of Joy!!!

This unit has brought my speakers to life. Back story, my father had a pair of E V Georgians circa 1964 that I was using a Denon integrated amplifier receiver to push them and the sound was not what I remembered as a boy. I hooked up the Niles Power Amp and all I can say is the speakers came alive. I am totally satisfied with this purchase. Thank you Crutchfield.

Excellent, affordable stereo power amp

Exactly what I needed. Was looking for a simple, affordable, stereo amp to pair with a Denon X3600H to utilize the A/V receiver's ability to process 11.1 (7.1.4 Atmos) channels via the multi-channel output. Anyone with one of these mid-level 9.1 Denon receivers that can process 11.1 should seriously consider this power amp for 7.1.4 Atmos. The ability to use 4 height speakers without compromising the rear surround channels is a game changer considering the cost of a 9.1 pre-amp + this amp vs the cost of an 11.1 pre-amp.

A Solid Replacement

So far so good. Had to replace my Carver amp from "1980", yes 40 years of service, not bad. All that is now left of my original audio system is a pair of ADS L710 speakers. My requirements aren't what they used to be, and there is where the Niles more than fills the bill of what I want and need. It appears to be an excellent piece of equipment and you can't go wrong with Crutchfield, as trusted name for many years. At the moment very satisfied.

This amplifier is quite remarkable...especially for the money! Used to replace an AudioResearch D-100 amplifier purchased many more years ago then I care to remeber for far more than the Niles SI-2100 cost me, I was not disappointed. The pre-amp is also an AR tube, powering the full range of a pair of top of the line Mirage Tower speakers. I can't say that I am missing anything, and it doesn't take five minutes to warm up. Yes, technology has come a long way in electronics but this is not necesarily so in audio, older is sometimes better. The Niles-SI-2100 stands proudly with the big names of years ago. It doesn't hurt that it weighs practically nothing and fits in a smaller space generating a considerably less heat. Thinking of buying another rather than splitting channels!

Good Choice

I am quite pleased with the SL-2100. Using for a home audio zone powering speakers in 5 rooms. Power is great. Significant improvement in detail and bass. I've always been interested in Niles Audio products though thought they were expensive. When existing Jamo amp failed and Crutchfield had SL-2100 on sale w/2 day shipping included it was too good of a deal to pass up! This zone is mostly working rooms (kitchen, laundry, garage). Too bad it sounds so good I'd like to sit and listen. I do wish Niles Audio published the power consumption specs so I'd know what it draws standby.

A good amp with even better company support!

I finally purchased a set of Bose 901s that I had wanted since I was a teenager. So imagine my frustration when even after much research, I found out that the "Tape" loop option I have on my receiver was not suitable for the proprietary Bose 901 EQ. In comes Crutchfield to the rescue! I explained my issue to Morgan and he took the time to look up the manual for my 11 year old receiver online. After determining that I couldn't use the 901s with my current set up, he researched a solution and suggested that I purchase a two channel amplifier as a work around. This Niles was on sale, and the reviews were solid, so I went for it. After about 14 months of happy ownership, the unit failed. I'm not sure why, but if I was forced to guess, it was because I placed it on top of my receiver and it was constantly operating at too hot of a temperature (I personally thought that the air flow was suitable). Since it had been over a year, Crutchfield was not able to help me directly, but they gave me the contact information for Niles. Even though my unit's warranty expired, Niles still serviced the unit for free, and were also very helpful and professional during the process. They had the unit back in about 12 days. Bravo! While the job of any amp is simple, I will say that this little amp cannot be turned up past 20% unless you want to get the police called. The power is clean, with no audible noise. And if you follow the airflow instructions, you will likely have zero issues.

Plenty of power

I have this AMP connected with Sonos Connect and four Niles RS6 Pro rock speakers in my pool area. It sounds great with plenty of power. The auto on feature is great and allows me to turn on the system from my phone. I initially purchased a Yamaha R-500 receiver but it didn't have enough power. This Niles AMP works great with plenty of power for four outdoor speakers.
