PCM 1792(A) vs. DSD 1792(A)

Other Parts Discussed in Thread: DSD1792A

Hi Everyone:

Could someone please tell me, what is the difference between PCM 1792 and DSD 1792??? I cannot be that the PCM version only takes CD-discs and that the DSD Version takes SACD's, because according to the D/A Converterlist at Dutch Audio Classics, the Denon DCD-SA1 Has Two PCM-1792's and it DOES play SACD'S (DSD), so IS there any difference between the PCM and DSD Versions or is it just two ways of saying the same thing???

My other question is, what the "A" stands for in DSD1792A??? Is the "A" Version a Further Developped Version with some other or better features??? Is it Radically Different, than the "NON-"A" - Version of the DSD/PCM 1792??? Is the "A"- Version a Newer and Improved Version of the PCM/DSD 1792???

My Third and Last Question is, that of the Three SACD-Players, that I am interested in.

1) Denon DCD-SA1 (2 x PCM 1792)

2) Luxman D-06 (2 x PCM 1792A)

3) Marantz SA-11S3 (1 x DSD 1792A) Actually the photo I have seen, depicts a DSD 1792 and NOT the "A" Version, even though the Marantz Website, says it is the "A" - Version.

Now my question is: of the three, only Marantz, has only ONE Converter. I Really would like my player to have TWO Converters, for better linearity, but the Marantz, with ONE Converter, is the cheapest of the three, so therefore my question is: Should there be any Significant Difference in Linearity and Sound Quality, Between a player, that has ONE and TWO PCM/DSD 1792's or is the architecture so advanced, that you don't really need two converters now, like you did in the 80'ies and 90'ies???

 

Thank You Very Much in Advance, I hope you can help me.

    Hi, Thomas,

    We are not really allowed to comment on our customer's implementation of our ICs.

    I suggest you might pose your question on DIYaudio to see what the people there have to say about the sound quality of the various transports you are considering.

    Hi Don:

    I am not trying to disclose how or why different manufaturers are trying to implement their converters, I don't care about that I just wanted to know if there were anything gained, by having TWO PCM/DSD 1792(A)'s instead of one, this has nothing to do with how different manufacturares are implementing your devices, I am asking You, since they are Your Devices, how they work and I am not trying to step onAnyone's toes, but simåply trying to fin out three simple questions:

    1) Are there a Difference between PCM and DSD 1792's or is this jsut a figure of speech and thus both the PCM and DSD designation can be used on both, since they are in essence they same Converter???

    2) Is the "A" Version of this chip an Upgrade from the Original PCM 1792???

    3) Are there any advantages to be acheived, by having TWO chips instead of just ONE, in terms of Linearity and Stereo Perception, in a Stereo Apparatus???

     

    Now these are my questions, pure and simple, I don't see what so ever, what that has to do, with how different manufactureres implement your chips??? I am not interestes, as I said in harming anyone, but just asking for expertise help, in choosing the right apparatus for me...Its not against the law to investigate and discern between products, before you decide which product is best for you, is it???

    I hope someone can answer me these questions.

    Sicnerely Thomas.
