I finally pulled the trigger on a pair of Musical Fidelity 550k Supercharger amps. This piggyback on lower power amps and could give my SP Tech Revelations the power they crave. So put them in place following my TacT amp as a starting point. But the bass was totally lacking compared to the TacT straight to the speakers.
Due to the SP Techs having biwiring speaker terminals? Any other ideas on what could cause this?
Will begin experimenting and see if this persists as a standalone amp (basically these are bridged amps functioning as monoblocks) or following a different amp...
Thoughts and suggestions are most welcome.
