Maybe buying a different amp

Did you mean MC312, or MA352?

MC352 and I've been using a B&K and I figured on spending up to 5k new or used.

There isn't much available in my area to visit and hear and mostly go by online reviews and threads on this forum for ideas.

Yes Bryston and PMC have a synergy, 4B3 is a fine power amp.

OP,

If you have spent years reading professional reviews and auditioning the units you have read about, then one can make good decisions made on the basis of reviews. However, if not… then one is looking for “better”.
 

The problem is that this completely leaves your own preferences out of it. So, for instance the really highly rated: Boulder, Luxman, Pass, Krell, Audio Research, Conrad Johnson and McIntosh have completely different sounds… if say you look at each of their $20K / units amp. There are only one in that list I would be happy with, and a total of three that I could live with.

Take a trip! Find the house sound you are drawn to.

I really think a road trip is in order for an expense of this magnitude. Your other option is to buy online and keep flipping them until you find what you’re looking for. Overture Audio is in Delaware and might be worth a visit.
