Acoustic Revive RCC-24.....any experience with

Tried it on the earth ground connection on my Nordost QB8. Does add some additional clarity, definition and depth but with the undesireable side effect of boosting the lower high frequency range in my system. Think too much sybalence on "s" words, particularly female vocals.

Any suggestions on how to mitigate this effect?

Anyone?

Try it plugged in to the ground post or RCA (using their supplied adapter) of your preamp instead.
