Bryston 4BSST or 6BST or 7BST

Vvrinc, how did you compare the bass (200hz lower) between 7BST and X-600 ? Transient ? I want to use it as bi-amp.

Thanks

The Bryston lacked only the subtlety of the Pass. The Pass is just more refined from top to bottom. However, in bass-slam, decay, the Bryston held its own very, very well. I had originally replaced the 7BST with the 7BSST only to discover that I liked the sound of the older model better. I sold the BSST and kept the BST until the move to Pass.
(Please note that I also prefer the sound of the Matrix Series III line of B&W to the newer Nautilus so if the words “old fart” come to mind as you read this post, it would be understandable.)
If you have an opportunity to hear the Bryston, I would recommend it.

Vvrinc, thanks for your comments. I find that interesting that you prefer the sound of the 7BST to the newer 7BSST. That is one reason I would steer away from the 7BST and get the 4BSST - because I would assume that the SST would sound better. Are the differences between the STs and the SSTs that pronounced that it is worth the extra money. I am still undecided which amp(s) to buy as there does not appear to be a clear winner except that nobody has really said much about the 6B.

I owned both the 4B SST and 14B SST. I purchased the 14B SST over the
7B SST monos due to space considerations, slightly less power
consumption and heat production. The 14B SST had better bass control,
had better low level detail and played more dynamically at lower
volumes than the 4B SST. If I had to do again, I'd purchase the 14B SST.

I compared the 4BST and the 4BSST and ended up purchasing the 4BSST because of the refinement in the top end. It simply sounded more natural to me
