BLOWN AWAY !!!! This is the first thing I can say ... not only is it insanely powerful, it looks beautiful. I am running the amp with a Macintosh pre-amp and a Marantz NA6006 DAC driving a pair of VERY thirsty flagship Polk 707's and the result is one of the very best sound stages I have ever heard in my life. HUGE thank you to Amir for setting me up with one of these, now I just need the 5 channel to complete my surround room !!
this amp was a perfect addition to drive the new Klipsch RF-7 III Floorstanding speakers i recently purchased this amp more than satisfied my needs also must not forget the same excellent as always customer service from Aamir
Awesome piece of equipment, couldn't be happier!
Purchasing from Aamir is like dealing with your best friend, no hassles and an easy transaction.
I will definitely be purchasing more hifi.
Having owned many high end Class A solid state amplifiers, the Summit HiFi 2 channel amplifier exceeded all expectations. I have used this amplifier with both large and small speakers, some of which are known to be very difficult to drive, but the Summit HiFi excelled in taking control with detail and musicality. I was so impressed with this amplifier that I have already ordered a second.
Thank you Aamir for bringing such a fantastic product to market and for your excellent customer service. You and your products have made for a very satisfied and loyal customer.
I used to drive my mirage m3si with a Bryston 4B but these Summit Hi-Fi & Tonewinner amp can equal the superb bass and very more musical.The midrange and treble completely out class the Bryson.looking for a powerful amp with tube like midrange,buy this unit and save some money for other gear in your system
