Primare Pre-30, Bryston Bp-25, Plinius CD LAD

I don't have direct experience with either of the above. However, if it helps, I also have Vienna Acoustics speakers and when I was originally researching their purchase, Primare was considered a good match for Viennas.

Hope this helps.

I've got a Bryston BP-6 (probably sounds more alike than different to the BP-25) and love it for its neutrality and crystal clear view of the soundstage. I'm guessing it will sound very different from your tube pre, so maybe something a little more polite would be a more palatable transition? I've got my BP-6 paired to a McCormack DNA 0.5 Rev. A and it's great, but when I had it hooked up to a Bryston 2BSST it was a little too lean sounding for me but might work with your Sonus Fabers depending on your tastes. Hope this helps and best of luck.

Soix. Thanks for your response. I am leaning towards the Bryston after a little more research. Any other advice or insight out there?

And thanks to music pod too! The primare is still in the running
