Hi Scott,
- Brystons ? The only model I've kept around ( & will continue to ) is the 2B-LP. I just love how this amp sounds with the rest of my gear. I sold off my 3Bs & 4Bs years ago. I never liked them very much ( IMO - not a titanium friendly amp - though I guess I should listen to the SST series ) . I've stayed away from the newer Brystons lines for various reasons. Interestingly; all Brystons models, past & present, have their schematics posted in pdf form at the Bryston website. All models except the 2B-LP that is. That makes me wonder since this particular topology is about 16 years old .
Cheers
ps : Scott, you're likely a 715P ( Sprague; Orange Drop ™ ) or MKC sort of guy / given everything you've said about the "sounds" of things . This is "Capacitor-Profiling" a regular poster . A new hobby of mine .
