Other than > 24/192PCM; you get > DSD64 DOP (+DSD Native) with USB. This is true for most if not all DAC not just the D-6.Hi!
To avoid electrical connection I prefer a Toslink over USB to feed a DAC from digital source (a workstation). Are there some reasons why USB can be better at D-6 use case?
It's the best bargain, USB-C in and balanced out!Final note - this is a really wonderful sounding DAC. I cannot believe that it only costs $170.
Firstly you can do free fully featured trial. It just stops playing after 30mins, so you just need to re-open every 30mins.I had never heard of HQPlayer. I went over and looked at their website - looks interesting. I would consider purchasing it, except there are some red flags along the way. For example, the 'Buy Now' and all prior webpage don't tell you how much it costs. Once you click on the button, it brings up the price (150 Euro), which is OK, but then it starts talking about hardware key, etc. The heck with that. I'd rather happily muck about with partial or non functional Linux open source and create my ideal setup..
Is it possible to use Strawberry level mixer for such files?SMSL D-6: Success with DSD over PCM (DoP) using the USB interface on Linux
I wanted to write up a quick summary of playing DSD over PCM (DoP) through the USB Interface from a computer running Ubuntu 20.04 Linux. After much futzing around, here's the formula that works for me:
I realize that this is a somewhat technical, what with having to compile and install software, etc. Also, I apologize to Windows users in this forum - I don't really know how to make it all work on Windows.
- Pre process the DSD ISO into .flac files that have DoP encoded content. I used the dsd2flac version published by this person at this github source tree - https://github.com/dhalsimax/dsf2flac (kudos to this person - the software has worked flawlessly so far)
- I used the Strawberry music player and configured it to use the backend ALSA SMSL USB Audio, USB Audio. If you run the command 'aplay -L', it lists the interface as follows:
- SMSL USB AUDIO, USB Audio
- Direct hardware device without any conversions
- The exact commands I used for the file conversion are:
- sacd_extract -i YOUR_FILENAME.iso -2 -e -C
- The above command creates a single dff file with all the songs in it, and a cue sheet file
- I got the sacd_extract program from the git repo https://github.com/sacd-ripper/sacd-ripper.git
- dsf2flac -d -i 'YOUR_EXTRACTED_FILE.dff'
- The above command creates a number of flac files with DSD over PCM encoding *and* the track information
- Now, when I start Strawberry music player, the track information is accurate and it often downloads cover art. Moreover, when I play songs, the SMSL D-6 displays '64' which, according to the SMSL manual, indicates DSD64!
Final note - this is a really wonderful sounding DAC. I cannot believe that it only costs $170.
Happy music listening, folks.
MPD (Music Player Daemon) deals with SACD iso and DSD natively. Have tried with D-6. The only problem - I can not use sotware mixer and am forced to use D-6 remote with P1 mode.
Have tried to find it in the chip's datasheet but was not lucky. I have thought PrX из D-6 config option rather than DAC chip itself.
Thanks for the clarification! But I still don't understand what is the difference between Pr0 and Prd? With Pr0 D-6's mixer is also turned off.DSD Direct mode passes the DAC chip DSP (volume control and modulator) and goes straight to switched capacitor filters and through to analogue output.
Pr0 still goes through the AK4493 modulator - you can see the path in block diagram - even though volume control is disabled.Thanks for the clarification! But I still don't understand what is the difference between Pr0 and Prd? With Pr0 D-6's mixer is also turned off.
This is an interesting alternative, something I will try this weekend.MPD (Music Player Daemon) deals with SACD iso and DSD natively. Have tried with D-6. The only problem - I can not use sotware mixer and am forced to use D-6 remote with Pr1 mode.
As for SACD iso, I haven't such one in hands now (don't believe in hires), but as far as I remember - have tried once - MPD understands those iso files accompanied with xml-file containing tags (I guess, something similar to cue). But the behavior is the same as with DSF files. MPD config file contains `dop` option which can be "on" or "off". At both cases D-6 shows "64" (with that DSF I try). At any case, I use USB, so DoP hasn't any sense here.This is an interesting alternative, something I will try this weekend.
When you use MPD and play SACD isos, does the D-6 say '64' or some other higher number? My understanding is that a lot of linux software is eager to transcode, and if the D-6 displays a higher number than 64, that indicates mpd has transcoded DSD to some high sample rate PCM.
