    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!!!!

    The best by far at any price!!!

    The best by far at any price!!!...I've been working on replacing my 1990's home theater system. I've always have been tech savvy, but the technology today is so much more advance since the 90's, so this meant a lot of research is required to get the best technology for the money with what my setup and needs are. Having said that, there are three components that makes up your home theater system, and each one is just as important as the other, but the one component of them that is most important of components, is quality amplifier! I have spent no less than five month and several hundred hours on line researching all of the three components, because I'm the guy who doesn't have $15,000.00 - $30,000.00 to buy the "so called" best of the best of all the components. I've come to find after all my time invested researching the actual specification, and the materials and internal components of these devises, that no matter what all these so-called influencers and so-called experts say on YouTube and on-line articles...It comes down to the Spec's, internal components, and material used. Not Name brand and price...More money in most cases is not always better! My home theater AVR is A Denon X6800H, awesome 11 channel unit!! I'd only recommend any Denon AVR for home theater! Right now, I'm running Klipsch speakers which are entry level but I'm going to make my final decision on speakers soon. If you hung in her this long, thank you! Now this is why I made the choice to purchase the Summit Hi-Fi A11 amplifier! I have eleven channel Denon AVR. Having said that, after looking into what is the most cost-effective way to get 11 channel Amplifier: do I break it up into multiple amplifiers or do I do one amplifier? What the research showed was, no matter if you bought multiple amps., or one to get the job done there was a set industry cost to the number of watts per channel your needs call for, and the number of channels your looking for, for your setup. (Again, set cost for watts and channels) Based on these finding I found that whether I break it up or not I'm looking at spending no less than $4,500.00 or more to get 11 channels amplified. Crazy!! You name the brand of amplifier and I looked at every spec of every one. Just when I was about to give up, this 11-channel amplifier pop up in a search and it was the Summit Hi-Fi A11 amplifier for less than $2,000.00. My first thought was this cannot be right! So, I compared the spec's, internal components and material used in this product and compared them to ALL the others, and after speaking with the owner, Aamir who by the way is the most professional, patient, knowledgeable and no pressure, not tell you what you want to hear just to buy his product business owner I've ever met with. His customer service is unlike no other. The product was promptly shipped, awesome experience!!...GREAT GUY!! I have the unit a week. Even with my entry level Klipsch's speakers the sound quality is AMAZING!! Not only can I hear sound now on all my eleven speakers so much better, I can now hear the rain, I can hear the birds, bugs, wind you name it now on all my surround speakers as well! If you are looking for THE BEST amplifier there is on the market regardless of price. The Summit Hi-Fi A11 amplifier is the one!! The last thing I like to suggest to anyone looking for an amplifier is, whether you have a five channel all the way up to an 11-channel surround sound home theater system. Bye this eleven channel A11. You may not think so now, but the day will come when you will upgrade and you will regret not having the most important and one of the most expensive items needed for your system when you do! You look at any so-called big name brand 3, 5, or 7 channel amplifiers out there. You'll spend more than $2,000.00 from any one of them!! You get it all with unit! I've been in contact with Aamir who is helping me with technical questions regarding floor speakers for my needs.

    What a beast! Heavy with a purpose, delivering ear candy with every ounce.

    First, let me start off by stating how great the customer service is from Aamir at Summit Hi-Fi. After I placed my order online for the Tonewinner 11-channel amp, Aamir immediately called and thanked me for my order. He then explained that for a short time, I could get the Summit Hi-Fi A11 for just a little more. I took the chance, and I am so glad I did. From the display, to raw power, this Amp delivers on all fronts. Went from a Monolith 7 channel amp, and I can tell you there is a significant difference. No noise/hiss at any level, clear audio delivery, awesome sound stage. The amp really brings my Emotiva speakers to life. Delivery was fast, with a minor issue. Customs opened the crate and damaged one of the feet, but Aamir immediately made things right! This is my second major audio purchase from Summit Hi-Fi and it will definitely not be my last. I would be remiss if I did not mention how big a value this amp is at the price point. No other amp delivers this big with 11 channels at under 2k. You will have to spend significantly more for the same power/channel count and performance with other brands.
