Think you can make safe assumptions based on price and copnfirm if really interested.It would be Accoustech or West and maybe Linn I'd check out asuuming they are NOT.Have red going from balanced to unbalnced once in chain (like say having unbalnced until pre-ouput and then needing a long run with low distortion you are not goin to screw things up (according to complete book of Hi-end written by one of Stereophiles editors.It's going back and forth that meses things up.That's why my UN-balanced McIntosh C712 pre(latter C15) had XLR out's for loing runs to power amp as does the $1K PS Audio GCPH phon I am proably going to get since not sure i want to swing a Rhea (if like the Steelhead it had even ONE line in might consider) well the PS has XLR out's almost positive it's not balanced.Might not be the achilles heal you thin it is.Hope you get more and better help.
