Very cheap alternative is 70's kenwood or kenwood trio models like the ka7100/ka9100 etc these go for hundreds of dollars and probablly have dirty coontacts but they did sound great. These aren't related to current kenwoods they are more related to accuphase. features= pure class a, dual power supplies and dc circuitry etc . Audio Classics are very good people and I purchased my new c2200 + mc2102 from them and they are always ready to help and service your purchase.
