Other sub amp for Gallo Ref3 secondary voice coil?

Hi - any Gallo Ref 3 users out there driving the secondary voice coil with a solid state amplifier other than the Gallo sub amp? The manual says you can use any 100WPC + amplifier that is stable into 4 ohms as long as a crossover (60 Hz or lower) is used.

I am driving my Gallos with tubes (with great results), and I don't have a "sub out" on my integrated. I was thinking about using a Rotel RB-1080 (200 WPC) to drive the secondary coil, and putting a crossover on the interconnect (like one of those little FMOD units). Just wondering whether someone had tried something similar...

I purchased a pair of plate subwoofer amps from Parts Express for about $125 each (part of a DIY subwoofer kit). I think the version I bought have about 200 wpc. The plate amps, of course, have a variable low pass filter, phase and level controls. I believe the cross-over is 24 db/octave. I ran the specs of these amps by JD at Gallo. He checked with Anthony and said they should work fine. They certainly seem to, though I haven't compared them to other amps. I'm sure they don't have the authority of a higher quality amp, but this was a pretty inexpensive solution to get a true dual mono power source for the second voice coils.
