Older McIntosh was considered the creme de la creme in it's last tube configuration befopre the tuners became solid state.Do a search for official Mac site and think there is a link to a site maintained by one of the previous employees with all the vintage stuff but their was one model that collectors coveted most that could be got for $1500-$2K.Other than a broadcast standard $5500 Magnum Dynalab some think it's the best ever made.Sorry I can't remember the model number but ask arround and Mac fans will know.Also have seen big market in old Fishers being re-built lately.Know that the cable company Mappleshade is selling them but you could get beter deal I am sure rolling your own.
