I don't know the answer, but with the addition of the optional TacT equalizer you might be able to restore some of the BAT qualities.
TACT 2.2X As Preamp? Or Run Thru BAT?
I am considering acquiring a TACT 2.2x to tame some heavy duty anomalies in my new room. Ideally, I would sell my BAT preamp to offset the cost of the TACT and use the latter for room correction and preamplification. Would appreciate any perspective on this unit (with d/A module) as a preamp. Or should I keep the BAT and use the TACT only as an RCS device? Though the latter would preseve all the right things the BAT does, I'm not sure its even feasible for one, and it does mean more connections and components in the signal path.....
