Nice, I'm glad to hear someone isn't experiencing "the micro-phonic ring of death!" LOL. Joking aside, I realize the ringing is not that big of a deal and I'm sure the majority of everyone else does too even though the subject has received ALOT of attention. My guess is because micro-phonics is a relatively rare phenomenon for amplifiers? I don't know too much about tubes and amplifiers as I'm just starting my foray into this realm of headphone HI-FI. I will say I can't wait to try the Vali + Modi when they arrive next week!
