New Audio Research Reference 150 SE

I am now over 70 hours and sonically I am at the point where I can say that the resolving power, detail, staging, lower distortion level (which I usually describe as the lowering of veils between the listener and the musicians) is noticeably better than the amp was before the upgrade.
What additional levels will I hear when the amp approaches 150-200 hours the burn-in time that Kal referenced?

out of curiousity (and as i need a repair soon), how much time did some upgraders spend without their amps? 3 weeks? more?

3+ weeks

How's you 150-SE doing at this point?? How about you, Bif??

Just have 45 hours. Getting better. It sounds better on some source music selections than others. Still to early to say. But it definitely sounds different that the Ref 150 avec KT-120s.
