Thanks! I used to- CJ driving DahlquistDQ10’s, crossed over at 80 hz to a pair of Dahlquist subwoofers that I drove with the Ampzilla. Now I toggle between the two amps. I really need an amp that sonically is between the two of them, and considering a variety of options. The CJ just blunts the leading edge of the sound for my taste, but it does have a great midrange.
