Yggy MIB burn in nearly 145 hours complete, and I think I need to clarify my experience a bit. About headroom, and intersample overs, I don’t think that was a part of my experience. Because -3db was good, and -5db was better ,
Hans Beekhuyzen suggests that in this situation you are dealing with voltage mismatch and synergy issue. Like a good doobie I adjusted sensitivity of amplifier and bang, no more running from the hifi. While this was a major win, Yggy MIB somehow neglected to play bass from like hour 3 to hour 140. I came back from the restroom and was like, WHAT? Wooomp, there it was. Not great, but present. FINALLY. Duncan Taylor used to be a testing tech at the music room, he described wild break in scenarios where bass would disappear, then magically reappear. If I remember correctly he attributed this scenario to power supply capacitors swelling and forming.
His podcast with PS Audio’s then Darren Myers was so fun. Yggy MIB is a fricken time machine, but, please, the bass, more please! Here’s to 200 hours and completely formed bass. Or wait, maybe what I’m waiting for wasn’t on the recordings to begin with. This hobby is sick.
