Audio Research Ref 3 Opinions

Hi all,

Sorry to bring back this old thread, but any one using or updated to the latest production version R3 with the Svetlana 6550C? have you try any NOS 6550 yet?

Regards,
JHC

I have now a Ref 3 that has just passed the 200 hrs break in mark. The unit is the latest version with new bypass caps and 6550C in PS. Stage opening up nicely with a significan amount of detail, authority, musicality, micro and macro dynamics. I estimate another 150 to 200 hrs to complete breakin process. I have no immediate plans to test NOS 6550 tubes at this time.

IMO there is absolutely no reason to do any tube rolling with this preamp

Wow, I came back to this thread to learn more of Guido's progress with burn-in, and I see that once again a bunch of posts have been removed. What happened? Another fist fight in here?

JAFOX, amazingly enough, I have been pretty good on this thread. Any idea what was nuked?
