    Don’t let the low price fool you. This is a top quality audiophile product. It replaced a pair of $3500 tube monoblocks in my system because it outperformed them in almost every way–much lower noise floor, great midrange warmth, sweeter highs, more resolving and better detail and no heat! Easy on the electric bill.

    My hat’s off to Tom. He puts out a very high quality product at a fraction of the price of most “audiophile” equipment these days. Even in the Class D amp market and digital amp market, his products kick serious butt.
