Maybe buying a different amp

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.

I have a mac 352, a Pass 250, Hegal 390, Accuphase 380. Before you decide Check out the Hegal and If your budget allows the 590. The Mac is ok, depending what speakers you will be using. The Pass and the Hegal wont care what speakers you use. If you have a large room and inefficient speaker I would avoid the 352. IMO it sounds better when its not driven hard, 

Thanks for the and ideas and replies. Traveling very far is out of the question right now hence why I stated that I'm basically relying on reviews and posts from audio enthusiasts like yourselves.

I have read quite a bit about some of the amps listed and I'm sure I wouldn't go wrong with any of them especially with my aged and tinnitus ears but the price would be a little out of my league for some.

I tend to like a more laid back sound and lots of bass. I do have a REL sub but unless I have time for a dedicated listening session I rarely turn it on.
