So in Linux you can use native DSD512 x 48kHz. Native DSD X 48k don´t work only in Windows. Now I get it. Thanks.

So Miska, the pro-ject already does DoP at 48kHz X 512 DSD in Linux? In other words, in Linux it accepts for DoP duties, 1536kHz/32bits PCM ? Then we need just an updated Windows driver to access DoP sample rates up to DSD512 (44.1k and 48k). Besides, with this bandwidth, it might be programed to do native DSD1024. John Westlake said in another forum: "We just might be able to upgrade the DSD to support DSD1024 via a firmware update."

If you play a DSD X 48khz over DoP file in the S2, the display shows nothing, if you pause the playing, it shows the respective DoP PCM 48khz rate.

Actually, I can use the pro-ject S2 up to DSD128 x 48khz in foobar. The DAC will display 384khz PCM, but it is DSD128 x 48khz DoP. With the older Windows driver in RELAXED buffer setting, it went up to DSD256 x 48khz in DoP 768khz PCM, with the new Windows driver only up to DSD128.

Anyone made dsd512 work in Windows? DoP or native?

Miska, seens you already had quite some time listening, and did some measurements with the Pro-Ject Pre Box S2 Digital. How did it compares with the IFI iDSD micro BL in sound quality, playing DSD256 or DSD512 native/upsampled files? I think, after following your postings here, that you are one of the most qualified guys, to give us this kind of information. Thanks a lot for everything.

KB did you ever tried to record in DSD128 (Nuwave and ADI2 P) or DSD256 (ADI2 P)?

It has won the EISA AWARDS 2017/2018 in the Hi -Fi Expert Group: https://www.eisa.eu/awards/pro-ject-pre-box-s2-digital/ "This petite box shows that – in the world of digital audio – less can be more. Its long list of features includes full preamp functionality and the latest ESS Sabre DACs running in dual mono configuration. So it handles everything from DSD512 to 768kHz/32-bit PCM music media and will even recognise and decode MQA files. High quality passive components, an integrated headphone amplifier and a host of digital filter options complete the big picture. With an open and expressive nature, and supreme versatility, the Pre Box S2 Digital sounds bigger and bolder than it looks – making it great affordable hi-fi." Dual mono ES9038Q2M mobile DACs, should be very good!

Hey Miska, which sofware is available for 705.6/768k PCM and DSD256 recording, with the ADI 2 Pro? For playback, native and upsampled files, I have a clue. Do you tested PCM 768k vesus DSD256 recording, from say - a vinyl source, which has the best sound quality? Just find this, Sound it! for ADI 2 Pro:

Concerning DSD128 and DSD256 playback, how do you rank the Mojo, micro IDAC2 and micro iDSD, for sound quality? I am seaching for a new DAC to use with my Adam Audio A5X monitors, and these 3 are in my price range, despite being made for headphone use.

The philips DST encoder thinks all DFF files are DSD64. After you process - say a DSD256 file - with it, the outcome DST file will be marked as DST64 and play four times as slooooow. You can use "set_FS" to change the header of this DST file to DST256. The only software that will play such a DST256 file is foobar with maxim SACD plugin, with quite a load on the processor. Took a year to someone else find my idea interesting, but all praise shoud go to Maxim for his programing skills. microTone

My DSD playing system is on the cheap side: Foobar + SACD plugin DoP to GeekOut 450 (Sabre Chip) to a pair of nearfield monitors Adam Audio A5x + Sub7 subwoofer. Can play only DSD64 and DSD128. In my system and to my ears, the best is Horus - Merging down to DSD128. Followed close by Grimm DSD64 original, and Horus - Sygnalist down to DSD64. These last two are near equivalent. I wonder if another possible file, Horus - Sygnalist down to DSD128, woud be the better one in DSD64 and DSD128 camp, winning from Horus - Merging DSD128. Many thanks for making this test possible, it is very informative.

@Larry Ho Thanks a lot for opening your thoughts and goals in the design process of Geek. I can really understand that your final goal is sound quality, within the limits of price and size of the device. And that you are testing all possible known alternatives. Well done and good luck.
