Spec units are rare and are sought after:
http://www.silverpioneer.netfirms.com/power_amps.htmhttp://www.silverpioneer.netfirms.com/pre-amps.htm"Pioneer did not traditionally build separate power amps, choosing instead to build a great line of integrated amps. But when Pioneer did build power amps, they were among the best in the world. There were four amps of note: the very rare M-22 and M-25, and the long-lived SPEC-2 and SPEC-4"
I saw 2 spec units kay Art Flores when I went to his place several months ago.
Sa buy and sell, here are some advertisments that I saw and pasted into an excell sheet. This should give u an idea of the asking price for these power amps in the local market.
