AA Prestige SE burn-in issue

Digital Drive

Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

I have this payer since October 2005 and after a few reliability issues (Philips transport), I ended up with a whole new motherboard (and transport).
After 2000 hours, only now are the tubes going through its burn-in cycles (from sounding great to damped/congested) - at this point an additional 1000 to 1500 hours is needed. My issue is around tube burn-in as it seems that AA factory supplied a motherboard without 'rippening' the tubes. Does this make any sense? Any advice?

Those are military-grade tubes and will last several.. - Carlos 15:32:46 11/25/06 (0)
