Why HDCD did not become a dominant format?

Fatparrot, Dbphd, just as you both have touched on with the Hybrid layer, and the HDCD re-master, I do believe many cases is the recording is just that much better when done in redbook with these formats on the disc, and the end result is they can sound just as good without the decoder in many cases, meaning sometimes it has less to do with the technology, but the better mix.

I think you're both right. The mix and recording skills are vital. Yes the RR recordings will sound great on any decent machine, however, IMO you haven't really heard them til you've heard them via HDCD on a comparably decent machine. I was very surprised at how much more refined the sound was via the old Toshiba SD9200 HDCD compared to the new Sony NS9100ES.

Differences with the hdcd are subtle .I had a arcam cd92 with hdce it sounded good,with hdcd cd's it still sounded good,but definitely was nothing groundbreaking.I've heard from more then one who said it definitely should have did better then it did.Of course going to greedy microsoft i'm sure didnt help its future either.

It is possible the differences stand out more due to the Spectral/MIT system.

Psacanli,

Appreciate your being conservative regarding repairs. However, EAD equipment is supported by Noble Electronics, which is a tech group composed of the engineers that pioneered the EAD products. Not only can they repair EAD products, they can update them...and they have an inventory of parts...and they are very fair with their pricing. They can literally build you a new unit. Now the best part is that the EAD stuff is built to withstand a meteor strike, so it will still be playing long after the Accuphase dinosaurs are extinct. If you have an opportunity, check Noble on the internet and it may give you a better sense of security.

Best.
