I found it better than CA 640C. Arcam had full bodied sound with bigger soundstage whereas CA was little thin for my taste. Cd73 is a discontinued model now. I think 15-18k is the right price for a used piece.
I am using one currently as a stop gap arrangement until I move to a transport/dac. It is quite good.
Definitely better than the budget kings like the Azur 640c, Marantz cd6000 etc...I have done A/B with both of these.
IMO a very decent cdp. Not as clean as the newer FMJ cdps but pretty good. I dont know if u will get a demo unit for 15/18K. I would think the range will be 20 /22K. This is a very different sounding player from say a marantz 6002/7001 and actually handles complex music better than most marantz but the marantz is a tad sweeter.
I also like a Nad C542 as a budget cdp. IMO a good option and that should be available used under 15K for sure.
