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 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
