Acoustic Revive REM-8
Another jaw dropper from Acoustic revive. Place the REM-8 under your amp, preamp, source power supply. It actually works to help cancel out the power supply's offending EMF field that it generates.
What you will hear
An immediate improvement in system focus. Much less smearing of instruments, especially symbals. Decays seem to decay longer and more naturally. No colorations that I can detect. Really quite extraordinary!
Tip: Treat the batteries with the RD-3 Demaginitizer first, then the RIO 5II Negative ion generator before installing the REM-8 underneath your component's power supply.
