the sound of my 4 times bose 901 and Denon chain is good. However, compared to my cd collection DMP acts playing less well. it is geschwafelt too much about the possible sounded representations. not bad for a test system, there is better. again, I recommend Amazon for example, the DMP recordings of tricycle, lynne arriale, Joe Morello or Thursday diva (follow me) etc ... to buy.
