ARC Pre + which SS amp?

I use LS-25 with Pass Labs X250.5 and I think this combo synergizes extremely well. Also, there is a nice difference between running ARC balanced or single ended. Balanced is always better. I tried.
I see you use B&W speakers.
FWIW, I found the X250.5 with LS-25 to work great with my B&Ws.

I tried the LS-16 last week with my Krell amp and it had a pretty nice sound stage but was lacking in the bass and a little bright compared to my PS Audio PCA2.

Brystons work fine for me. Don't believe all the "Brihgtsun" crap.

adamg, very timely post. I am in the market for a new preamp to mate with my Pass XA160 amps. ARC Ref3 is on my shortlist.
