    That is an A to D process.
    Apologies for that, however I did reread your post (#27) and don't see anything that would have lead me to believe it was only and specifically about high resolution digital streaming.

    I would respectfully say MAY, not would. Every time an engineer puts his/her hands on an original recording there's a chance they will put their stamp on it with changes, even if it's the original engineer (even unconsciously). Most of what I hear that has been reissued, remastered, whatever, and released on 24/96 doesn't sound as good as the original 16/44, if the original had the proper attention paid to it whether originally analogue or digital source.

    Agree that it should, but often don't. Have you listened to an Adele 24/96 stream? Awful.

    Agree with not necessarily, but it COULD sound as good or better. Especially with some of today's higher quality d>a converters that can really extract resolution from 16/44 recordings.

    An A to D process then an D to A process...
    This appears to be exactly what's happened based on the Post article and subsequent YouTube video with the engineers saying that's what they're doing. Again, I have no issue with it other than lack of transparency.

    Mobile Fidelity says these albums are sourced from the original Master Tapes. That's their thing. The engineers confirmed it in their video.

    I wouldn't argue this point at all, it's a personal preference. My personal preference would be for a first generation tape of an analogue recording at 30ips. Failing that, or for a digital recording, digital playback.

    Hi Rusty,

    I agree and this is what makes fine stereo sound reproduction such an interesting past time.

    While worthy of a thread on its own the impact of psychoacoustics cannot be underestimated on what we think we hear or donít hear.

    Once you throw these factors into the mix (sorry) itís hardly surprising some people resort to snake oil remedies. Green felt tip pens for colouring the mains power pins green, zen stones and cones to keep your speaker leads off the floor are among the more amusing things l have seen over the years.

    https://en.m.wikipedia.org/wiki/Psychoacoustics

    This is where Clarkís desire for Headphones has the advantage. I confess to preferring sound coming from outside my head!

    Not to out done l recently engaged an expert acoustic consultant to assess my new listening room for the purpose of critical listening. No it wasnít cheap. Following an exchange of some information he completed a modal analysis and specified a range of acoustic treatments. He made the comment my large 4345 loudspeakers were very cool! I have implemented some of the treatments over the weekend by improvisation and the difference in the listening experience is positive. Musical instruments are easier to identify and the overall listening experience is more enjoyable!

    It will be interesting to see how l fair with different recording qualities?

    Attached is a measurement l performed of the before treatment status to confirm the modal analysis.

    Donít ask me what it all means? But apparently the reverberation time is too long and there are some problem room modes.

    I remember reading an article regarding possible formats that were being considered for use in the upcoming manufacture of the "digital compact disc". Under consideration at the time, but unfortunately for the consumer dropped due to its higher cost vs. (is it 44.1K, 16 bit?), was an early variation of DSD. It is state of the art DSD that MoFi uses in their process.
    The adoption of the lesser Fi format, which in general can achieve great reproduced sound when the mastering engineers know what they are doing, do it the best they can, and the end to end process includes the best efforts, care and skills of all those involved, had DSD been the format of choice there would have been very little reason to complain about the sound reproduced using that technology. It really is that good.

    Both Sony developments. The corporation has also been responsible for pretty much every new amplifier class since the Williamson, possibly excepting Nelson Pass's explorations. While Sony did not first market Class D, they invented it. The CD was a joint venture of Sony and Philips; the European giant did the hardware (the player) but the software was all Sony.

    Sony's commercial success now rests with game systems, creating and distributing films, and vast holdings of intellectual property. But the history remains. It is a multinational outfit; the Sonoma system and hardware for recording DSD was developed by Americans.

    If you look at the time line in this link Denon were the forerunners and Sony commercialised the recorders.

    I personally prefer Denon as a hifi brand over Sony. Denon is a more conservative brand but they know their market. Sony has a habit of ditching technology like the Betamax and mini disk. They jump on an idea and you buy into it and they leave you up shit creek. They are big in television cameras.
