    AD 1 'PA + AD 1 Pre Mk ii

    I have just love my AD 1 PA power amp. Excellent in build quality and sonics. Very smooth presentation yet dynamic lows in class AB mode. The star is the AD 1 Pre amp. Stellar performer for a SS preamp. Matched it with the high end YaQin 4 Tube CD player and just sonic nirvana. The phono section is amazing too. Highly recommend both products & ask Amir to pls start stocking the YaQin 4 tube CD players for his customers. Unmatched tube & SS sonic sweetness!

    Great sounding amp and excellent value

    I bought the amp based on reviews. The customer service from Summit was excellent! Ultimately, I will be using it to drive 300 hz up in an active tri-amped system. I received it and wanted to burn it in and listen to it full frequency. I pulled the Michi S5 and am running the AD-1 in Class A from 60 hz up over the sub. The amp is very clean, articulate and open sounding. I dont think you can find a better sounding and well-built amp anywhere for this kind of money. I would highly recommend this amp!
