I know of these: pass xono, ear 324, aesthetix rhea and io, bat vk 10, hagerman trumpet,........................................................................................................ but am not sure of the others like: manley steelhead, arc ref., tom evans groove, asr basis, acoustech ph1p, linn linto, cary 301 or 302, clear audio, herron vtph-1, art audio, whest p.20, zyx, artemis, ayre, clearaudio reference, rowland cadence, klyne, etc etc.Thanks for the help.

Among those I know -- Asr, Klyne, clearaudio, rowland are. But really Pedrillo, why don't you just check these peoples' web-sites?? Cheers

Einstein makes a superb balanced phono preamp. I have the single ended version which is VERY good. The balanced is even better.
I don't believe any of the unsure ones you mentioned are balanced. The exception might be an Art Audio, which I think uses transformers on the output. That is, you get balanced outputs, but not balanced gain and eq circuitry. Same goes for Audio Note. Actually, the EAR might be in this category.

One you missed is the RTP from Allen Wright.
