I know this is an older thread but I recently picked up a Audio Research CD-1. The Rega vs the Audio Research CD-1 is a no contest. I demo'ed both units and the CD-1 is far superior. Greater resolution without glare, superb well defined bass and a soundstage and image that are spectacular.
Audio Research CD-1 vs Rega Planet original
I am considering an upgrade of my present CD player to either the Rega Planet (original model) or the Audio Research CD-1 for about the same amount. do any of you folks have any experience w/these 2 machines?
