I have had problems with four different pieces of Audio Research gear, so after 10 years of struggling with it, I changed to the Ayre-K1xe and I absolutely love it. to me the Ayre K-1xe sounds better than the ARC Ref II MkII preamp I traded in. And I am relieved to be rid of trouble. Try to listen to an Ayre K-1xe with your system. I think you will be glad you did. Tube woes can drive one nuts!
