    Your recent blogs on the JAS HD Audio requirements particularly those concerning replay equipment prompted me to check the specifications of my own gear. It turns out that my power amp has a sensivity of 10hz – 20khz and my speakers 20hz – 22khz. My dac is the Benchmark dac2. Does this mean I will gain no benefit from HD Audio recordings (24 bit/96-192khz) apart from the fact that some, yours especially, will have been properly produced and mastered?
    As I’m not about to change my gear any time soon and, if, as I suspect this applies to a large percentage of music buyers and certainly to most of the equipment currently for sale, then, surely, the whole Hd Audio hype is an even bigger con than the scams (re-marketing of old recordings as something they aren’t) that you have exposed.

      You’re going to get great sound out the gear that you have. The specs of HD-Audio are very demanding and will only be delivered by a new generation of gear…and that’s OK. HD is very hard to produce and it will be difficult to achieve as well. Think of of it as the equivalent of moving from a very nice sports car to a hand made Ferrari. It’s not going to be for everyone nor appreciate by everyone. The content, software, hardware and speakers all have to step up.

    I recently picked up the Sony STR-DN1050 A/V receiver which supports just about every HRA audio format and I couldn’t be happier – I’m sure the DACs aren’t quite as good as the HAP-S1 but it was a cheap ticket into the HRA game (as a college student on a budget cost was a concern for me). Full disclosure: I work for Sony Pictures and received a 25% discount which clinched it for me as the Pioneer VSX-1124-k spec’d similarly was also tempting. If Apple makes their 24-96 files available I may be filing for bankruptcy.

    “From the information that I read, it doesn’t say whether the band was also part of the “live” recording but I would assume so seeing the video of “Anything Goes”. The video shows both artists singing in the same room but the band is not present. It’s the way I’ve been making records for 15 years… with everyone in the same room singing and playing as an ensemble.”

    Mark,
    Sorry but I don’t understand the above comment unless there’s a typo somewhere.
    You say the video shows the two vocalists in the room but none of the musicians. Then you say its the same way you record with. “with everyone in the same room singing and playing as an ensemble.”? How do you record, with everyone playing in the room at the same time or some other way?
    TIA,
    Sal

      I should have been more clear. The Bennett/Lady Gaga sessions were done in a commercial recoding facility. They separated the musicians from the singers but still recorded everyone at the same time. It is typical to isolate drums and other instruments from vocals. My own recording have everyone on the stage of a large auditorium…

  • Don’t hold your breath, the CD at least has an average crest factor of only 9.5dB. Not as bad as most, but not brilliant either….

      That’s disappointing. I did hear a track yesterday at the New York Audio Show and it sounded very good but was compressed.
