Any Bryston 4B3 amp owners out there?

I found on the 2b3 and 4b3 they need some time to break in and sound there very best, also they sound much better after about 4 hours of warm up.
The Pass Labs gear is also wonderful but if it's in a smaller room it can really heat up the room, Great Sound From A Great Company!

To chandybe:
I got your e-mail about the Mark Levinson amp and sent a personal response. Thought I'd respond here as well.
I checked Audiogon's "For Sale" listings and found three ML 532Hs for sale. I also did as much background research as I could (via internet) and found the consensus rating on SQ to be excellent. It's a dual mono amp that revealed no weakness to the reviewers. One reviewer didn't care for it's "looks" (I like the appearance), but that was the ONLY complaint. Reviewers really gushed over this amp. The price new at the time of reviews was $8500. The three listings ranged from a little more than half new retail to a little less. Those three amps looked like a steal.

I was considering the ML 532H for a while too.  The heat sink placement (cannot stack or put in tight top bottom enclosure) and rear binding posts were a turn off.  I also don't think its made with the same care and quality as their highest end gear and more suited for home theater (could be wrong).  There is one for sale at a super low price but with some cosmetic issues.

hikmer,
I've seen pics of the ML 532H, the most revealing were with the lid popped off. Internal heat sinks don't seem like the best idea (glad you brought it up) and it's built on a "one size fits all" chassis. The obvious reason is a cost saving measure. More models on a single chassis is kinda what GM did with their cars about a decade ago. It is on my short list to buy, but I the checkbook won't come out unless I have concrete assurance that it could be returned. I've had buyer's remorse with new, that risk is elevated with used.
