Well there is a list with fully balanced pre's noted by the asterisk.
Please feel free to correct any mistakes, I visited the websites of these companies to assertain the fully balanced feature.

Jeff Rowland Pre info as follows:

** Criterion:
Main out: 2 pair Balanced (XLR), 2 pair Unbalanced (RCA)
Record out: 1 pair Balanced (XLR), 1 pair Unbalanced (RCA)
Note that Price of $12,000 used is hypothetical. . . there have been no used Criterions on the market yet as far as I know, and I'm not selling mine (grins!) .

** Capri:

** Concerto

Thanks for your response and sorry for the delay in responding. I've not been on A-gon due to work in quite a few days; it's great to hear from you!
