I have mentioned this to a few people already but when it comes to Ayon cd players, I have yet to hear the CD-1 but I do have a CD-2 here and to my ears, it's the best sounding cd player I have heard to date and I have heard a few good ones including the Naim CD555.
The plus for me with the CD-2 is that it also acts as a standalone DAC.....and it's a darn good DAC.
Really nice stuff and better than I was expecting.
I have a Raysonic 168 here and I would agree with the review Carl posted. They look alike but after that, the similarities end and honestly, it's not even close. The Raysonic is a great piece but the Ayon takes it up a few notches.
