    TW AD-8300

    Solid amplifier. Simple clean design. Quite no hiss. Highly recommended.

    Just got this into my rack and added it to a new JBL Preprocessor and speakers. So far so good. The amp pushes my speakers will relative ease and I’m looking forward to getting the speaker through the break in period so that I can really listen to the difference this amp has made to my system.

    A beast in a suit

    This was one of the best purchases I have made towards my home theatre setup. Reticent in looks, but grabs attention when it's on duty. Built like a tank with elegance. Brought body and heft to my LCR with wider imaging and the surrounds are more lively giving the punch when the movie demands it. Shows no sense of strain even at reference levels and beyond. Just keeps going. And while doing that, the thing stays cool to the touch. I never managed to get it to kick start its fans. Power is the only attribute it adds. And the amp is quiet. With highly sensitive Klipsch reference tower speakers, it is pin-drop silence from my listening position. Truly happy with it and would recommend it to anybody who wants a pure power amp that delivers power.

    TW AD-8300 - 11 CHANNEL AMP

    I couldn't be happier with the performance oft his amp and the service provided by SummitHiFi-USA. I would highly recommend them for your electronics needs.


    Everything was as advertised...this is a fantastic amp!! My little theater has come to life even with my dated AVR. My only gripe which made this a 4 star review is the delivery. The ticket called out for a signature and UPS just left it on my doorstep. Not happy about that UPS!!
