    HDCD was a bit of an odd format. The process required the master to be HDCD encoded, and the audio to be HDCD decoded, upon playback. As mentioned, the Pacific Microsonics chipsets were the best, but they typically only appeared in expensive, high end gear. I had a Parasound DAC that could decode a HDCD disc, and while it didn't use the Pacific Microsonics DAC's, it still sounded very good.

    Also, concerning 'false positives'. A master needed HDCD encoding, but the PQ Subcode (the Table Of Contents / TOC of the CD) also had an area set aside for HDCD. There was an ON/OFF 'Flag' that needed to be set to ON, if HDCD encoding was present. I'd often receive master tapes, with no encoding, but the TOC HDCD Flag had been set to ON. So, on playback, the CD player would activate the HDCD display, and try and decode the audio, but there would be no audible benefits.

    The Hejira HDCD sounded great with decoding. It remained my reference tillthe HD version got released.

    I have a (copy) of a Garth Brooks thats stamped HDCD but it does not have any of the headers. I don't know if it was manufacturing defect or what. 5 different copies behaved the same.

    What is "the HD" version? I have BluRay PureAudio of a couple Albums (Quadrophenia and Beck's Sea Changes, for instance)
    that are both gorgeous - but they are BluRay

    Thanks for reminding me, I just downloaded the HDCD plugin for Foobar... you do have to paste some code in to actually display HDCD though.

    192khz 24bit from HDTracks.

    BluRay audio? Heard of them....never invested in one. I never saw that going anywhere.

    Ah, thanks for the info - so its purchased/downloaded HD tracks ...

    About the PureAudio discs, well, since I already had the Oppo BluRay player - all it cost was the discs ...
    Quadrophenia: [Blu-ray PureAudio] $19 shipped.
    Sea Change [Blu-ray PureAudio] also $19 shipped ...
    Since I like both albums and Sea Change in SACD or any hiRes format was unobtainium, it was a fine price. And I do like having a physical disc of my media.

    Yeah...I remember when both "Pure Audio Blu-Ray" and "High Fidelity Pure Audio" which were different initiatives for a Blu-Ray audio format by two different labels were coming out. The main concern was yet another failure for a disc format that was hindered by being a different and slightly incompatible standard like DVD-Audio was to DVD-Video....but apparently both work on standard Blu-Ray players and are (I'm guessing) just uncompressed PCM audio containing literally just audio. I almost bought one a time or two do see how hard the audio would be to "liberate" from the disc.....but I never actually heard much about it. I still don't know where the format stands...I'm pretty sure I could go on Amazon or something and get some for about $20/each to give it a try...but most of the stuff released on those has wound up on HDTracks/AcousticSounds. The thing that got me was most of the Pure Audio releases I saw on the initial list were just 96/24, though 192/24 was supported. Maybe I should look in to if they're still releasing stuff on it or if it's gone the way of audiophile niche like SACD has.

    But that's basically all Blu-Ray audio is....just HD PCM audio formatted for Blu-Ray. I could probably make them if I knew the specifics of how the disc was formatted.

    Physical media is nice; but I learned a very long time ago it has the downfall of being physical...so damage and theft have been the two downfalls with me for it. So if it's a physical disc I back it up...and if it's downloaded it goes in to the collection...which gets backed up in 3 places.

    Even the SACDs.

    Seriously.
