Tube Preamp for 4B SST2

There have been a lot of folks who have used Bryston with ARC
with great synergy.
A few years back when I home auditioned a ref 5 with my 7B-sst's I liked it a lot.
Didn't find anything non musical about it except the I couldn't afford it at the time.
Would I have bought it if I had the coin,of course I would have.
Now I use 28s with a Vac pre and am very satisfied.
Might want to look on older posts that have arc and Bryston.
There are quite a few on audiocircle also that use tubes with the Bryston.
Hopefully you find your specific arc pre with Bryston.

Zd542: what makes you think that these other brands should be less chancier to match than ARC? from the previous threads in Adiogon it seems to be the safest combo after Bryston pre and power.

I found very few threads contains information about SP17, I need some comparison between different ARC Pres like LS15, LS16, LS25 compared to SP17.

I can recommend both CJ and Manley preamps working well with Bryston and have them through a 4BST.

Am specifically interested in the ARC Preamplifiers as they're the only ones I can get buy but without auditioning.
I need some comparisons and experiences between ARC Pres, specially SP17 which is offered to me

I don't think ARC preamps are consistent in their overall sound. For example, some models sound bright while others don't. Keep in mind, though, that's just my opinion. No doubt, not everyone would agree.

I don't understand what you are saying there. If you are buying without listening first, you should be able to get just about anything. Why just ARC?
