I have been offered a Pioneer SA-9500. This is of course an integrated amplifier. When is an integrated better (I am in limited space, so that has an influence). I am running a McIntosh MC2100 with a C712. The Pioneer is a quality piece as well. My stereo setup is set up on a budget. If I want to upgrade -- or just hear a different sound -- where do I draw the line? Should I think McIntosh uber alles?
