HDCD Decoding?

[G9logitech]

Hey Guys -

Sorry to ask yet another question, however, Denon's customer service is closed right now and wanted to ask the pros' of the pros'

Does the Denon 3800 play & decode HDCD's?

Also, I see there are regular HDCD's and then theres those expensive HDCD's that say something like 24K gold HDCD (by extreme fidelity)... Will there be any noticable difference in these 2 HDCD's?

Just asking as regular HDCD is $12.00 and the 24K extreme Fidelity HDCD is $30.00

Thanks guys
