ECBA up, as I know a few of us are interested in one. Unfort this one is higher than I'd want to pay, particularly with no EML 300Bs.http://www.head-fi.org/t/630493/eddie-current-balancing-act-like-new-plus-many-extras$3650 with Craig's recommended stock tubes.
Is the 2.5 the same as the A? Or is there an updated version of both the MK2 and A?As far as I'm aware, there are only four "official" versions of the SR-007: MK1, BL, MK2, and A. Some insist there's a sonic difference between the MK2 and A, while others insist the only difference is cosmetic. I'd imagine if there is a difference it would be extremely minor.
