interesting. I was never a fan of the 7XX preamps, but i really like the MP series pres.
FWIW, I'd put the 788 pres against almost anything that's out there. They're ridiculously cheap nowadaze, taboot. The PSP2 probably would still win a blind shoot-out, but it would be close. The 788 preamps are definitely not the same as the others in the 7xx line, nor are they like the mix-pre preamps, which I also own. The 788 are way WAY better sounding. (Not meaning to sound argumentative here...just pointing out that IMHO the 788 shouldn't be lumped into the discussion with the 744, 722, or 702...again IMHO.)
