Ampzilla 2000 v2 and Mcintosh MC402

@ghasley I actually seriously considering a new Pass Labs amp. My borrowed x150.5 sound great with my Mcintosh C1100 preamp (even better than the MC352 itself).

I am exploring the option of having a new x250.8 as my next amp. 

... By the way, none of the Pass Labs Preamp I came across can even come close to the C1100 Pre. But somehow, my Mcintosh Preamp paired very well with my borrowed Pass Labs Power Amp.

While I understand your affinity for your Mac preamp, I wonder if you have tried an ARC preamp IN YOUR ROOM.  It may not be for you, but if you have not tried one, I would give it a shot.  Try the newer ones or the older ones--be sure you stick to the tube versions.

Whatever you decide, enjoy the music!

Cheers!

Have purchased a couple of McIntosh integrated and power amps. Never stayed long as they are not my thing. We bit overhyped in my opinion.

Have never had the pleasure of the Ampzilla products, perhaps one day. 
 

Quite enamored with Norma Audio and my collection of European tube integrated amps.

@richopp I tried at least three different models of ARC preamp. Those ARC tend to have more resolution than the Mc Preamp, but always sounds thin and bass-shied ... Overall, ARC is more hi-fi than Mc, but will drive me out of the room sooner or later due to boredom.
