Hi, all. I currently am using an MX130 pre/tuner with an MC7106 six channel power amp. I am looking to replace the 7106 with a smaller two channel amp, since I only use two channels and would like to reduce the size and weight as compared to the 7106. I have considered replacing both units with an integrated amp. My problem there is that I need a tape out or other facility that is not controlled by the volume control so that I can run my wireless headphones (they have their own amplifier). The current Mac integrateds don't have this feature. Anyhow, I'm interested in a used 2 channel Mac power amp, solid state, that is not too old. Say, from year 2000 and newer. Any recommendations? Thanks!
