Amperex PQ 6922 1960 matched pair D Getter 063. I believe I've done okay. Spent some bucks to be sure. What kind of burn in am I looking at for both the cans and the tubes? Hours? Days? Weeks? And what kind of music should I use or does that matter?
Thank you all for the previous messages. I read most of them but so much to comprehend and learn about. BTW, my other cans are Bose QC15 and Sennheiser HD580.
Tube burn in can be debated, general consensus is that they won't really change. Just be sure to let your tube warm up properly on the first few uses.
As for the Grados, I have a friend who listens to several models and he religiously burns them in for a minimum of 100 hours before commenting on the sound signature. You can still listen to them during this time, but past about 150 hours the phones should have settled into their signature.
My preference for a burn-in is this: http://www.jlabaudio.com/burn.php
I'd just plug the headphones directly into the computer to avoid unnecessary tube wear, and start this before leaving for work or school. When you're using them you can listen to whatever you want.
