Denon 3805 and HK630/635 has a HDCD decoder.
In my case, I could use my CDP's (no HDCD capability) toslink and HDCD would be diplayed on my HK630's front panel. I also recently disovered that my GIEC upcoverting (video) DVD player also had HDCD, funny I didnt notice it for a year
, but I dont know how to be sure if it really does HDCD cuz the receiver already has a decoder. But since its a more popular brand in HK, I would assume it does.
There are tons of these HDCD capable players in Hong Kong (just saw them yesterday) but the good branded (HK brands) would cost you around 6-8k pesos.
