I have and compared the KBA-75 to many amps, Rowland M-112, Krell KAV-2250, Pass X-250, Spectron Musician II, Linar Audio, etc. The Kinergeitcs held its own pretty well where I did not feel that I was loosing that much and in some cases the Kinner was more musical. I am not familiar with your amp but it is in the same family. I have the KBA=75 2 channel amp for sale which could aslo somplete your system.. I did buy the Pass Labs 250 amp but I think a better power cord, ICs and speaker wire may be the bigger bankg for the buck.
Happy Listening.
