Let the Lyr run all night and day so there was some additional break in.. meh.. next..
Just dropped the Amperex Holland A-Frame in.. revved everything back up and am going out for a 2 hour ride. BTW.. the Amperex is giving off a foul smell, can't really describe it and I assume that it's just new tube normal burn off. Nothing seems to be overheating or smoking after 10 minutes and liking the sound better already but no 'Holy Schiit!' yet. Will see what it's like after my ride.
~~ Next Day Update ~~
The house didn't burn down, no more foul smell, let the Amperex tubes run for about 12 hours and swapped out the Matrix Mini-i DAC with the PS Audio DLIII from my main A/V system. Holy Schiit! Nailed it! This combo is really sweet. I really can't afford to get a second DLIII but the BiFrost may do. Over to the BiFrost thread to see if there are amy comparisons between the DLIII and BiFrost.
The nasty toxic smell isn't the tubes, it's the amp. It's probably the soldering dope or some protective coating on the trasformer windings or something like that burning off. Mine stank horribly for about 2 weeks or so each time I'd turn it on. And I had two of them...in the same room No tube change produced an odor, so it's purely the amp. it does go away completely though, it's just "new amp smell"
