  • HDCD will sound ‘worse’ on system that does not support HDCD dithering process, since extra process will be present as just added noise on unsupported system.

    That said, those pricing is for nutjobs and this is what gives really bad impressions to ordinary people about HD-audio market.

  • Here’s the flip side of things from my HO, this is a golden age for CD buyers and music collectors.
    The Doors Morrison Hotel,, there’s 101 copies listed for sale on ebay, one of the first ones that comes up is $5.00 with FREE shipping!.
    I’ve been rounding out a lot of my collection lately and the prices are fantastic. I just got a copy of Stevie Wonder’s Songs in the Key of Life for the princely sum of $3.69 Free Shipping!
    Yesterday I ordered David Gilmore’l On An Island for $5.00 FREE Shipping.
    Everything I’ve got has come in pristine condition and has good Red Book sound.

    But last week I bought The Animals Retrospective from HDTracks for 19.95 and it sound like crap.
    I also bought Marvin Gaye’s What’s Goin On from HDTracks for 17.95, it doesn’t sound too bad but I’ll bet $100 that’s its no improvement over a Red Book CD.

    I don’t mean to rant but you are right Mark, the provenance is everything. Since my taste in music is more on the oldies side I don’t see myself buying to many more HD high priced recordings. Sorry to see the CD dieing,it really is a shame. But it can be a windfall for music collectors.

    • I honestly think what the guy in Australia is doing is buying the products he sells for retail (or wholesale) and then upping the prices to make people feel like they are valuable.

    Regarding cost When prerecorded movies on VHS first came out, they sold for prices in the neighborhood of $120-$160. One never knows what will sell.

    I have new CD from Japan of an old Nils Lofgren akbum. IT is an HM-CD – which menas that it is made from anew materia, but i can’t determine what the new material is or even if its the music layer of the substrate.

    About a decade back American Gramophone re mastered all the Fresh Air albums for HDCD, but I can’t say that they made ised of the expanded dynamic range.

    • One of the types that I left off the list was the single cut glass CD…which is another hocus pocus rip off. A CD is a CD is a CD…and no new materials or substrate will alter the sound at all!
