Just Wow

Built like a tank, well packaged, cool Vu meters, clear sound and power to spare. Plays well from low volumes, to way too loud for extended periods. I've never owner a quality piece of audio equipment such as this, and I'm so glad I do now.

My speakers have just come alive, with a level of detail I've never heard before.

At the introductory price this amp is selling for, and with the risk-free trial period, you really can't go wrong.

Add to that the advice and patient answers to my questions, I know where my next audio purchases will be made. Thank you so much Aamir.


Folks, there are very few times in my 57 years on this planet that I have felt compelled to write a review before I have had an opportunity to experience a product. In the context of experience, I experienced something today that is so rare in the age we live in. After my purchase last night and after countless hours of research trying to pair quality and price , today the man himself- Aamir called me personally to converse about my purchase. Humbled and honored to speak with him, it was like talking to a lifetime friend. I can't tell you how excited I am to experience my new A7 when it arrives and to my audiophile friends who have provided their experience with the product, because of Aamir, I am proud to be joining you in the land of audio excellence. Thank you again Aamir!


no words can describe my happiness
since the first day I am in love with this machine steticly and musically
80+ pounds no joking.
my previous amp was a Well Knowing Parasound 5250 v2 250rms per channel,
and the A7 with 200rms per channel is superior in all aspect highs,mids,bass like no other. or at least like bigger and more expensive amps
what other reviews saying is exactly what you are going to experience.
an honest and warm friendly costumer service by Aamir.
thanks again Aamir

Just like the title says I am very impressed. It's very heavy but besides that it's very clean sounding screen looks cool and lots of power. I highly recommend this amplifier half the cost of other and sounds amazing. I'm so glad that I bought this unit and will recommend to anyone that's in the market for one.

Summit HiFi A7 - Risking House Damage

Firstly, I would like to acknowledge Summit HiFi's outstanding customer service. I texted Aamir inquiring about upgrading from an AVR into separate processor coupled with his house brand amp - the A7. Within minutes he called me back and we discussed possible options. Aamir goes out of his way to speak to his clients and assist them with their AV requirements.
Now - this amp... BEASTLY !! It's crazy heavy because it's built like a tank on the outside with two toroidal transformers, individual circuitry, capacitors and heat sinks per channel on the inside! Seven channels with 200w PER channel! I tried to turn the volume up in my house but comfortable listening levels did not even make the digital VU meters bounce. I mean, clean, neutral, dynamic sound that wasn't harsh or bright - just truthful. Even played at loud levels the amp did not get hot - fantastic heat dissipation.
I've had the amp for just over 2 weeks so I hope it has surpassed burn-in period. I aspire to make the VU meters dance!
