I have not heard the Cayin but recently had the chance to audition the Arcam. It is very good, and the price is around $1,000 if you bargain. Try Monsoon Home Theatre at Paragon. The service is excellent and there is no pressure to buy. But be warned, you and your money will soon be parted!
If you budget allows, perhaps you might wish to consider a Arcam DV78, and get DVD, MP3 playback together with your CD player, for around $1,800.
Cheers!
