Very interesting, thanks for your review.
However, I'm personally leery about buying from PD because of the horrendous lack of support I got from them last year... It took them almost two months to repair a grounding issue that later resurfaced, and then they never gave me back the upgraded buffers I had originally bought when they finally shipped it back to me (I was a senior citizen by that point). James was always amicable though.
I really can't speak to that because I've not had to deal with any return/repair issues for any of my PD amps.
