bradz, i must 1st say that i'm extrapolating here, cuz i've never heard a rogue66 or an aes preamp. but, i *did* do a direct comparison between a rogue 99 magnum-updated preamp, & a cary slp98. this was in my home, for a couple of months. the cary won hands-down, in all areas. based upon this, if it were me, i'd get an aes preamp, if these were my choices. but, at this price-range, i'd get a melos sha-gold-r/maestro over *either* of 'em! ;~)
ymmv, doug s.
