Any Bryston 4B3 amp owners out there?

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.

This just posted...I'd grab it McCormack DNA-2 LAE SMc Audio Signature Edition

I would say the Parasound A21, Pass Labs X250.8, and Bryston 4B3 will sound different from each other and it will break down to your personal preference. Meaning you would benefit from hearing them in person if at all possible.

In my opinion, the overall sound character of the Pass Labs is closer to the Parasound than the Bryston is to the Parasound.

I recently picked up a 4B3 and find there is nothing it is lacking it's sound. Previous amp was a Classe CA-201 that I liked but the Bryston just sounds all around better IMHO. Rest of system is Canton Vento 890.2 DC,  BP25 pre and Teac PD H600 cdp.

You have a nice system there and I recommend you demo a 4b3  if you can. 

I know that the Pass 250.8 would probably musically be the finest of the bunch. It's reputation is that powerful. Again, the heat, size, and the fact I'd have to buy used (probably no returns) are negatives I have to consider. The reason I picked on the 4B3 is because I can actually audition it at home, it's at the extreme of my price range (new), and Bryston's build quality is bulletproof. I live about 2 hours north of Audio Advisor, so I could order the 4B3 one day and have it the next. They're also super with returns. If I can find a used amp for $6K or less that has a reputation for singing with the angels and built to last, I'd consider that as well. I received a personal e-mail that brought Simaudio into the discussion. I have limited experience with their products, but was really, really, really, impressed. I'd have no problem with one of their finer two channel amps (used).
