Tube Preamp for possible Bryston 4B SST2 amp

I bought a Bryston 4B-SST2 and wanted an Audio Research REF3 preamp. I bought the Bryston BP-26, really only to avoid tube replacements..
I half wish i had aquired the ARC REF3. As I bought a VAC Standard tube just as a buffer for the digital.
Hindsight is 20/20. but I think i should have bought the REF 3 instead of the Bryston. Though at this time i would not swap them. (more for $$ and bother than any other reason.) As I am very happy with my setup as it is.

Lloyddelee21: I would say the treble of the 4B-SST2 (all squared models) is superior to former bryston amps.

I do not have a lot of experience with many other amps.
My former amp was a Forte'4a (which has an excellent body of reviews stating it is a great little amp)

I am a high frequency nut. the Hf has to be perfect or I am not interested. I have to say the Brystom fulfills my every need.

When I auditioned it twice over several hours, listening to my own CDs.. i found the treble to be exquisite.
All the clarity and purity i demand from my equipment.
I am totally happy with the amp in my system.

The Bryston preamp is fine too. just i sort of wish i HAD bought my first wish, a used ARC REF3.
Just because I like ARC stuff too. At this point i do not have the extra cash to wast selling the Bryston and buying an ARC. And I am really happy with the sound anyway, and have NO IDEA if i would love the sound as much with an ARC REF3 in thesetup. Crazy hey.
