I have a pair of ca 1960 Marantz 5 mono blocks rated at 30 watts. I will shortly be connecting them to Merlin VSMs with single ended BAM. The amps are placed next to the speakers and connected to an Audible Illusions 3A preamp about 2.5 meters away. Does anyone have experience with these amps or suggestions for wire and interconnects to achieve a little more neutral sound from these pleasantly warm and musical amps? Thanks. Tim
