ok. i had to hold off on this one. i was hoping this would die down cause for the first time in many months a gaines audio pre was on ebay. and i wanted the name to keep a low profile! just closed-- going for $278 for a two channel pre. (i was outbid)
anyway, they are really great pres for the price. i have a single channel one that i got off of ebay for $68 bucks that has a reichenbach input transformer and a three stage op amp gain design behind it.
compared to my earthworks pre, they are nicely moderately colored. say off-white. little smeared on top and a little fuller on bottom (but without the ultra low extension of the earthworks).
they have like 70db of clean quiet gain.
additionally the designer of the pre is a very affable guy, you can write him an email about anything and he'll respond. i have asked him about a few of his products.
anyway, certainly worth the under $300 for the two channels.
