I've never had a CDP with the HDCD For about ten years, however, I have a CDP that also reads the sacd, (Labtek HiEnd, which also reads the DVD). 3 years ago I also got another CDP with the sacd (Yamaha CD-S3000). Both readers like me a lot. The Labtek is slightly "warmer" (so to speak), while the Yamaha is a little more detailed, even if I do not think it's right to say "colder" on the contrary! I have hundreds of CDs in sacd format, some pure sacd, almost all "hybrids". Some of these also have HDCD. I have never heard the difference between SACD and HDCD. For your experience ... How much difference is there between one and the other? and ... What are these differences? Is it worth it, to buy a CDP with HDCD? Neil Young records, for example, are often HDCD encoded but do not have the sacd. I quote the great Neil, but, of course, CD with the HDCD I have others too. I think there are about fifty, those with HDCD, on my shelves. The word is yours.
