pabbi1 - Have you received your McAlister EA-6 amp yet? If yes, then how does it sound?
AFAIK, I am the only one that has (had) one.
When last we spoke, Peter was making some changes to the amp based on what I was hearing, both for gain, and quality. I simply have to defer comment about overall sound quality until hearing the amp perform as Peter and I both expect.
However, to expect a $1700 retail amp to sound (even slightly) better than an amp that was > $1700 in parts alone (my Blue Hawaii) is very difficult proposition to fulfill.
As soon as I have the EA-6 in hand, burned in, and with sufficient evaluation time, I will post impressions regarding it, compared to a variety of other well known electrostatic amps, and a range of phones, including the HE60, OII, and OI, with other seasoned Head-fi alums opinions as well.
Finally, I am also most likely selling one of the amps, as I need only one, and the BH is already serving me very well.
