mikey8811 Posted October 10, 2019 Share Posted October 10, 2019 Thanks guys! You have all been very helpful to a novice like me. A lot better than some of the other threads on this forum where questions do not even elicit a single response. I have also been trying to understand the difference between DoP and Native DSD. I also keep hearing the term DXD being bandied about especially in conjunction with dCS Ring DAC's. I was always under the impression that DoP is basically DSD in a PCM wrapper and sonically identical. It appears from this thread that it isn't. My streamer, an Auralic Aries says it does DSD up to 256 natively via USB BUT on the Processor Setup page, under Resampler Configuration, it says DoP for DSD64 and DSD128. There do not seem to be other selectable options My DAC is a PS Audio Direct Stream which says it accepts DSD natively up to DSD128 via USB but when I play tracks via the Auralic Aries it shows DoP on the front panel. I am guessing this means I have been playing DoP and NOT native DSD. What am I doing wrong and what can I do to play DSD natively? Thanks Link to comment

It appears from this thread that it isn't. Your original understanding is correct. The only difference is the wrapper, not the DSD data. Once the package is accepted by the USB input on the DAC, it is processed the same way as non DoP DSD. If someone says they are sonically different, let them prove it (hint: they can't). And again: DoP DSD is "native DSD". The DSD itself hasn't been altered. The term is incorrectly used by some to try and make it sound like not using DoP is superior and different. Non native DSD is supposed to mean DSD that's been altered by conversion to PCM , or possibly multibit DSD (point of contention), which is what many forms of playback/processing do to DSD. This has nothing to do with the DSD file being sent as DoP or not. some help: http://help.nativedsd.com/en/articles/63529-getting-started-playing-dsd-and-dxd-files https://www.northstar.it/dsd-native-vs-dop/ https://dsd-guide.com/dop-open-standard Main listening (small home office): Main setup: Surge protectors +>Isol-8 Mini sub Axis Power Strip/Protection>QuietPC Low Noise Server>Roon (Audiolense DRC)>Stack Audio Link II>Kii Control>Kii Three BXT (on their own electric circuit) >GIK Room Treatments.

There do not seem to be other selectable options That is because the DoP wrapper adds to the bulk of the data transmission. Putting DSD64 or DSD128 into DoP practically doubles the size of the package being transmitted. As a result, putting DSD256 into a DoP package exceeds the bandwidth that the Auralic will support even though "native" unpackaged DSD256 does not.

mikey8811 Posted October 1, 2020 Share Posted October 1, 2020 Hi @ted_b and @Kal Rubinson Just reviving this thread as I ran into issues downsampling some newer DSD 256 files to DSD 128. I basically tried doing this again using the TEAC converter programme. However, this time, while the files can convert and be played, the resultant DSD 128 files were ridiculously large. For example, an original DSD 256 file with the size of 468.1 Mb became 1.47 Gb after conversion to DSD 128. Is there a reason for it? As per my earlier post and your replies, it would seem that the file size should be halved from DSD 256 to DSD 128. Thanks Link to comment

Thanks I've converted DSD 256 files to DSD 128 and the resulting files have always been smaller. I wonder if your DSD 256 files are in compressed DSD format (DST).

It doesn't have many settings - you just pick the frequency ie. 2.8 Mhz, 5.6 MHz or 11.2 MHz for DSD files and if you want them as .DFF, .DSF or WAV (and the corresponding bit rates) That's pretty much it. Do you use another free programme you could recommend? Link to comment

mikey8811 Posted October 2, 2020 Share Posted October 2, 2020 I resolved it - I just deleted the DSD 256 files. I have a redbook CD of the same material and compared them. Turns out the DSD 256 which was about 5 Gb plus in size sounded pretty similar to the redbook at 186 Mb - less hassle and less drive space. It was a pretty good recording already Sarah Vaughan's "After Hours" on Roulette (1997 Capitol CD vs High Resolution Tape Transfers DSD 256) Thanks everyone Link to comment
992Sam Posted October 2, 2020 Share Posted October 2, 2020 I've been following the discussion here... I too am relatively new to the digital music side of the house... I was wondering, if I come across some disks at my local used record shop that are labeled DVD Audio, or DXD, can I expect them to play thru a latest technology transport and be read by a latest generation DAC? (my stuff is in my signature block)? separately, and moreover, even if I get rebook CD content, doesn't my DAC upsample into DSD anyway?

According to the McIntosh website, your MCT500 supports SACD, CD, CD-R/RW and DVD-R; popular file formats such as AAC, AIFF, ALAC, DSD (up to DSD128), FLAC, MP3, WAV (up to 24-bit/192kHz) and WMA. So, no. BTW, I've never seen a DXD disc, have you? 2 hours ago, 992Sam said: separately, and moreover, even if I get rebook CD content, doesn't my DAC upsample into DSD anyway?

ted_b Posted October 2, 2020 Share Posted October 2, 2020 DXD is not a disc format, it is a marketing term for 24 bit PCM recorded or transferred at 352.8k or 384k. There is no disc that houses that. It (DXD) was created, initially, to provide those with DSD masters a high resolution enough PCM container to do editing in PCM, with the thought that the resultant edited recording would be re-transferred back to DSD. When DXD is used as the original recorded format it is often released as original PCM, too. But I have never heard of a DXD disc. ? 992Sam 1 "We're all bozos on this bus"....F.T.

The files I’ve downloaded from the website still sound wonderful, though, with two exceptions... 3) The exceptions are the two Reference Recordings files I bought, one in 256, the other in 128. Specifically, these are Honeck conducting Bruckner’s 9th and Beethoven’s 3rd, respectively. My DAC says it can play DSD up to 256. It is connected to a 2017 MacBook Pro via USB, and it is feeding the signal to a THX AAA 789 amp. Nevertheless, to test if my setup can handle 256, I downloaded both the free 256 sampler and the 256 version of Raizes. They both played fine, so I decided to buy the 256 Honeck Bruckner 9. The file sounds like a CD skipping. Thinking the problem was that my DAC was having problems playing 256 (even though it can handle the other 256 files perfectly), I made sure to buy the 128 version of the Honeck Beethoven 3. But same problem! What is odd is that I now have 11 downloads from Native DSD and all the files from other labels play perfectly, whether they are 64, 128, or 256. I’m only having problems with the one label (Reference Recordings). Any thoughts as to what might be happening? Link to comment

Now, it's easier to flag those that don't play DSD :) ) I will check further. 3) Please send a note to Jonas at Native. He will check with the label. I have no idea why other files play fine (you are lucky to be getting DSD256 via Mac cuz often the Mac driver is only capable of half that speed). I will ask him also to check.
