I haven't heard the Cambridge so I can't compare the sound quality of the two players. The advantage of the Cary is that you can do a lot of tuning with it. Tube or solid state output, no upsampling or various rates of upsampling, and tube rolling. So you can tweak the sound quite a bit.
Cambridge 840c vrs used Cary 303/300
I've been seriously considering the Cambridge 840c CDP. Many like the way it sounds after broken in. They sell used here almost every week. But, I've seen some good used buys on Audiogon for the Cary 303/300 CDP. I'm running with tubes in the preamp and amps. I like the build of the Cary model. Any comments of owners who are familiar with both would be appreciated. Either choice would be an improvement to my current CDP. Thanks!
