A used McIntosh C220 might stretch your budget, but if you shop carefully, could be obtained. It has balanced and unbalanced outputs, and has no issues driving long RCA runs into my SS amp with 10K input impedance. Like all recent McIntosh preamps, it is designed to drive either tube or SS amps. My C-J PV11 that was replaced with the McIntosh, not so much.
Need help with a Tube PREAMP.
I currently use a Solid State 2 channel AMP with an Input of 20k(unbal) 40k(bal). I am looking for a great Tube PreAmp for around $2500 that would mate well with the AMP. any suggestions would be greatly appreciated.
