I have not compared one vs the other but i have listened to both extensively. my dealer handles accuphase and that is what they generally have playing. they also handle mcintosh. when looking for a new amp i listened to both however you cannot listen and compare apples to apples. the mac was the mc402 with output transformers and 400w/ch,selling for 5k, the accuphase was their a60, class a operation 60w/ch, selling for 16k. Unless you have unlimited funds the mac is the way to go. Was there differences sonically, yes, enough to spend another 11k, not for me.
If I did have the funds however; i would probably go with 2 A60's bridged.
