I was very happy with my purchases from AVA right out of the box. Everything was better, and I should know because I've listened to the replaced components for 20yrs. I'd better be able to hear the changes, even with my less than perfect hearing.
Two nights ago however something seemed to change. I wasn't listening seriously. I was playing solitaire on my lap top with the system on playing a live recording by Maria Muldaur. Suddenly I looked up. I would have sworn she was in the room. I thought to myself, "Must be the rye." , and thought no more about it. Last night I put on the third disc of a three disc set by Steeleyespan and began to play solitaire once again. No rye. Gout you know. Same thing happened. Maddy Prior was in the room with me. I put away the laptop and paid more attention. I couldn't believe what I was hearing. More space, more there as Sam Tellig would write. Up until now, I didn't believe in break in, but it's the only explanation I have. I've owned my T-8+ now for about thirty days. Use it about 4 hours a day. Have my tubes run in? I have no previous experience with tube gear and to be honest I've never believed in nor have I heard any previous differencess with other components other than speakers which are mechanical and probably benefitt from a break-in period.
Anyway life is good and the music is better. Lots better.
