I have a Pioneer rack with SPEC1, SPEC4, TX9500II, CT-F100,and RT-707. Have a turntable on top, with an extra shelf above it for a CD/DVD player. The SPEC 1 has an extra output which I use to feed a Maggie 9304. The Maggie sounds great using the SPEC 1 preamp, and I get to use all of the Rack components to feed either system. Somedays I feel like Solid State, Some days Tubes.
