Which headphones were being used, HE90s, OIIs? Any preference between them?
I really enjoyed the soundstage of the Lambdas, even over the O2s, but the HE90s were the most refined and realistic by far. I purchased a pair of Lambdas as a result of that listening session, in fact., since I am in no position to afford HE90s ATM.
I regret not hearing, nor even seeing, the Supra at the meet. As much as I appreciate Mikhail, and as much as I enjoy his tremendous amplifiers, he has consistently and grievously dropped the ball on your gear, Elephas. Hopefully the good reports are at least some comfort.
