I've been bi-amping with a TacT RCS2.2X for 3 years. The previous format was a Placette passive Linestage and a modded Dahlquist DQ-LP1, which combo proved extremely transparent. What very slight loss of transparency was experienced has been more than compensated for by the ability to make room/speaker/woofer corrections in the time domain, choose a 60db/oct slope w/o phase shift, and smooth my low end frequency response(in the room) to with +/- 2db from 20 to 250hz. No losses whatever in sound staging, imaging, immediacy, or timbre, but rather a much greater sense of being present in the recording venue. Some of which I have(as a reference).
