pre-amp for original Marantz Model 9 mono amps?
What pre-amp would you mate with a pair of museum quality pair of original unmodified Marantz Model 9 mono amps? Also available is a pair of Marantz Model 8 mono amps for rear channels for a home theatre setup although assume a two channel setup is the objective here.
