In Reply to: RE: Upsampling everything to DSD SACD posted by srl1 on November 17, 2020 at 19:18:39
I also have Marantz SACD player (SA10) which converts CD files to DSD format instead of using a traditional DAC. I think it does improve the sound, especially the soundstage, compared to the other players I have tried....these include an Onkyo, which was very two-dimensional, and also a Marantz SA14, which was much better than the Onkyo but still not as good as the SA10. The SA14 did have a USB input to its DAC that could accept DSD input up to 128 from Audirvana, but the SA10 does 256 and sounds better, I think. There is now a Marantz SACD 30n which also converts CD to DSD but which costs much less than the Ruby or the SA10 and which has much better network capabilities.
I haven't read much about it yet.

Nice. I have an SA10 too. In theory, converting 16/44 to DSD would make for a bit of harshness since the upsampled version's frequency is not an exact multiple of 44khz. It would have been an exact multiple of 48KHz or 96KHz, but not 44KHz. But the SA-10 sounds just beautiful.
The DSD clock is an integer multiple of the standard RB sample rate: 64 * 44.1kHz sample rate i.e 64fs is 64 * 44100 = 2.822400MHz
The bitstream runs at 2.822 MHz in order to overcome the limitations of a 1-bit D-S modulator which necessitates aggressive noise-shaping to achieve a decent SNR in the audible range. Consequently, the response may theoretically extend up to 100kHz, but the noise-shaping is designed such that the bandwidth for maximum SNR (120dB) is 20kHz which matches the Redbook specification.

Yes. You are right. I forgot. Actually the SA-10 has two upsamplings - 11.2896MHz and 12.288MHz - being integral multiples of 44.1KHz and 48KHz respectively.

So they sensibly maintain the oversampling ratio according to the base clock - I had wondered what would happen in that instance.
Thanks for the info!
BTW Happy New Year

You have had your SA-10 for quite awhile now.
I really need to add this spinner to my Collection.
Do we know if Marantz is stocking spare drives/laser mechanisms for future repairs?
The Marantz SACD 30n seems ideal. Heos built in, SACD, CD.
Here's a review.
bullethead-
which SACD players have you owned ?
