Wish I could have made it Luther, looks like a great time. Since my available time was limited, I hung out at Mike's and we played vinyl for a few hours. At least I was there in June! Is the AMR a new piece for you, or did someone bring it? I've always liked the build quality of AMR, but have really only listened to their DAC very much. How do you like the music from the CD player?
You are not alone with that experience, unfortunately.The bigger the event, the greater the chance of a tube failing.....at least that's my experience.
Looked like a great get together, I've always enjoyed visiting friends houses and having them round at mine for a listening session and swapping bits of kit in and out the system, it's what makes hobby such good fun!
