SS intgtd- Ayre; YBA; Sugden; Bel Canto; Accphse ?

I'm a fan of the Bryston B-60 but it is playing well out of its depth relative to Ayre AX-7e or the Bel Canto eVo 2i II. I have heard the Sugden but not in A-B situations and I haven't heard the rest of your list at all. You might want to also check out the 47 Labs Gaincard (no remote, no balanced input) which is excellent in some applications (no comment on why it costs what it does) or the Lavardin which I have not heard but hear interesting things about.
I'm not familiar with your specific speakers although I've found some Coincidents I've heard on the bright side even with tubes.
I'm afraid that you you already have a reasonable list to work from and that further culling is going to come down to your ears. Good luck.

Howdy Sutts!
did you ever get more info on the BelCanto SET40i that are/were interested in? Thanks!
Were you considering the BelCanto for a diff system?
Just curious to know. Thanks!

Hey Bombay! Yah-got in touch with your buddy about the SET40i- thanks. Have decided it's not going to be a contender- no cover for the amp, and new baby will be crawling soon... That EvoIIiGenII integrated sold pretty fast the other day @ Underwood Wally's price of $1,890- wonder how good that piece is??

Jeffjarvis- any idea if Sugden has dealers in North America? They used to have a distributor up here in Canada- Plurison I believe, out of Montreal, but I don't think they carry the line anymore...

Greenman- I do think Ayre product is excellent, but I like tubes somewhere in the chain- getting off track for a second, perhaps my modded SF Line 3 preamp might stay in the 'A' system and would match up nicely with a V5Xe? I assume that combo would be a notch above the Ayre integrated?

Ellery- re: Bryston, as much as I wanted to like it, I could not warm up to it- and that was the latest 14BSST, even with my tube preamp...

I have heard the Ayre V5 and the Sonic Frontiers SL3 but not together. I think it has the makings of a great match, probably many steps above the AX7. I think very highly of both pieces
Have you called Bel Canto to ask about a cage for the SET40i? I'm fairly certain there was an optional cover. Whether they still have any in inventory may be another matter.
Without a direct A-B I'm guessing, but I think a Sugden A21 may lack resolution and bass drive relative to an AX7e or eVo2i II. The Sugden is, however, very smooth and musical.

Sutts,
Cool!
I'd 2nd Greenman's reco & call up BelCanto to see if they can provide a cover/cage for the SET40i. I'm sure that it's possible to make for a reasonable amount.
The sound from the SET40i is totally kick-butt! If your speakers are upto the job, you won't regret the purchase.
FWIW. IMHO.
