It seems that Macs are are very synergistic with karaoke systems because I've seen a few of those.
Macintosh vs Pass labs
I currently own a Pass X250 which is awesome. I am driving Von Schwikierts VR4 SR also awesome. I have always wanted to try a Mac amp. However I am wondering why there are always so many for sale. Pass amps are few and far btween. Maybe th grass looks greener on the other side. Thanks
