    This amp rocks!

    Really really impressed with this amp — using it for 11.1ch music in my media room and it sounds fantastic. Replacing 3 Sony TA-N9000 amps and they just don’t even compare. Build quality, packaging, build quality, customer service, sound and punch all 100%. Very very satisfied, thank you very much!

    This amp rocks!

    First impressions — super fast shipping, fantastic packaging, and super build quality. The amp really feels like a high end piece of equipment, and I really appreciate the quality speaker binding posts — made installation a breeze!
    Currently I have an older Yamaha 11.2 non-atmos preamp and I had a Parasound NC 5250 along with 2 Sony TA-N9000es amps running 11.1 with f&r height speakers. 4 years ago or so the Parasound stopped working and I switched to a 9.1 setup using the Sony amps. Immediately something was missing — movies were ok but music was just no longer as enjoyable. But now, now with the a11, that all has changed. Back to 11.1 and all the speakers sing! Better than I remember with the Parasound, and definitely better than anything I’ve ever had before! The Sonys would run out of gas and it seemed like my speakers were about to blow, but now with the extra power my speakers seem to handle loud volumes with ease now — much smoother even though I can now play even louder. Music is fantastic — details I never noticed before now come through with very nice extension into the highs. I spent my days off listening to my collection, and I look forward to many more days with this lovely monster. Thanks again for the super service, much appreciated!

    You may think your avr is good enough, and it may be. But who wants good enough? If you have the means, do yourself a favor and just buy it. You're welcome. Even 2 channel the difference is blatant. It's not subtle at all. It's priced way lower than it should be, honestly. And the service from Amir is even better than the products he sells.

    Absolute beast of a unit!

    This thing is freakin heavy!! You will need help lifting it out of the superbly packaged box. Btw love the packaging, very robust! This thing is n absolute power house!! It’s got my floor stage thumping and it’s barely breaking a sweat. The vu meters are very responsive and the screen can get very bright or dim. I’m very happy with my purchase and Aamir was very great to work with. I absolutely recommend this amplifier if you’re in the market for one. The only thing I would change about would be channel designation on the rear terminal panel. With the double stacked rca and speaker terminals I wasn’t quite sure which one was left channel speaker terminal or right speaker terminal. At first glance it took me a second to realize that it was spelled out in the instructions so thankful for that but me being new to all this having them marked near the speaker terminal like they are on the rca would’ve been a nice added touch to make it even simpler to hook up which it already is super easy. Anyway if you’re thinking about buying this amp stop and just buy it you won’t be disappointed at all.

    Equipment used: denon x3800h. Klipsch klf 30s, c7, rp160s, rp500sa. Mini dsp, sinbosen fp14 and gsg audio subs.

    Awesome Amp, awesome service!

    I’d been looking for an amp to upgrade my current Denon AVR X6700h to a pre amp system. I came across this amp online and I have to admit I was skeptical. I’d never heard of Summit Hi-Fi. I’ll tell you now, I’m sure glad I took a chance and ordered this beast . The amp runs my 7.2.4 Dolby Atmos theater perfectly. Plenty of clean pure power and a noticeable improvement to the sound stage. Honestly, the amp should cost a lot more for what you get. When you order yours and hook it up, you’ll be writing a review just like I did. The product, service, delivery and performance is truly impressive. Great job Summit Hi-Fi!!!!
