Belles 350A Ref / Ayre V-1XE / Pass Labs X250.5

Have not heard the Belles but had the Ayre and Pass 350.5 when I had my Thiels. I preferred the Ayre. it was just a little smoother, and fuller sounding in my system. i now own Harbeths and think the Ayre amp would match well. Which Harbeths are you thinking about getting?

Try the Pass XA100.5/160.5 series if you prefer smoother & silky mids & highs. The X250.5 is more on the dynamics.

Super HL5s.

I dont think you will need the kind of power you are talking about getting to get the most out of the SHL5s.

I agree with Tom Hankins. I have my Harbeth M-40.1's powered with 125WPC Plinius SA-102 amp and the power is more than adequate.
