I haven't really heard the BAT amps, so i canno't comment on them. However i too own a Mac MC352 partnered to a Supratek Chardonnay. Source Linn Genki soon to be upgraded to Ikemi maybe...This combo sounds fantastic. The only problem being the supratek will not offer you much flexibilty in HT (it has a bypass )unless you want to seperate the two.
Good luck !
