New Audio Research Reference 150 SE

Still early to post detailed comments. The sonic color of the amp is still morphing ... first dark and now bright. I only have about 25 to 30 hours on the amp.

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

Herb ...

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