Mcintosh c22 60th pre amp has anyone listened to ?

I know there were only 60 sets sold , but was looking at a purchase of the pre amp only and was trying to compare it to the mcintosh 2300. I understand the mc on the phono is very good and if anyone is actually using it with there phono?
Since they were only offered as sets, I'd be careful about how much you pay for it. The C22 and the C22 series 2 were both classics...
Do you know what the right price would be since the set would have been broken up?
call audio classics for a professional opinion. nice guys, and they know mac better than most.
