Judging by your other gear, you might like an older Carver C series pre. These have enough knobs to satisfy any knob junkie. They have a fairly complex tone control section - more than just a bass and treble knob.
Tone controls? Sorry about the heresy.
I need tone controls! Too much of the music I listen to needs it. A lot of 70's, 80's, 90's, 00's rock. Some acoustic music. Who makes excellent preamps with tone controls OR what other box can I use that won't degrade the sound too much? Currently use a PS Audio 4.5, Adcom GFA-555II, JPW speakers.
