Hi All Head Fi friends

It is better that we share our knowledge here about DSD music file

In the past 1 year every body talking about DSD music file

Everybody like to know what is DSD music file and what is the different in term of sound quality to WAV ,AIFF , FLAC and so on

And now every vendor bring their new DAP and DAC / Amp on the market with DSD playback
The first native DSD DAP is AK 240 if I am not wrong ?

I am as zero computer / digital knowledge like to know what is DSD music file and how can we make our file in DSD music file ? And so on

If possible with the link that we can read the information about DSD music file

Thank you

Here some link to DSD = Direct Stream Digital

My biggest concern now is the noise floor when it comes to this type of file since it is one-bit in depth. The hiss is really very audible especially when it comes to playing this in my 901.

I have a few dsd songs, running on the AK-240, have not noticed a hiss, Will get to downloading a few albums this week sometime.

Are they 1-bit/2.8Mhz or higher? The 901 plays DSD by converting to PCM, I believe and the hiss is very loud.

 

[kh600rr]

1-bit/2.8Mhz, I believe, I'd check, but I just put my laptop and AK to bed for the night . I think I read somewhere else today about a hiss on the HI with the wolfson dac. But yours has the sabre If memory serves me. It was the JHA Roxanne thread

 

[gerard14ph]

DSD sounds really good thru my desktop, but with my DAP, not a chance because of that hiss.

 

[kh600rr]

Maybe a firmware update could help.

The issue isn't with DSD but with the 901. DSD support on the 901 is still beta. As per kh600rr, you may need to wait for the next firmware (although DSD support on the 901 was quite a few firmwares old and subsequent firmware upgrades hadn't attempted to fix the DSD issue yet).

Now that brought some light, bro. Thanks. Now DSD will just be desktop for now.

I thought I'd share my thoughts here on DSD, although I probably have longer "experience" with SACD rather than DSD as I've been buying SACDs since 2000. Back then it was buying SACD and their equivalent CD's and comparing on speaker systems. Comparing between the two was a hit 'n miss. Some like Dave Brubeck's Take Five it wasn't difficult to hear a difference between the two but some other SACD vs CD albums, it wasn't so obvious.
 
For DSD on the other hand, all my 24/192's come from the same SACD/DSD source (I'll leave it up to you to research how extraction is done). In that case, at least in my home iMac -> Invicta -> Stax I have to admit I find it hard pressed to hear a difference. I don't know if it's because 24/192 is truly indistinguishable from it's DSD source, or during the SACD -> DSD extraction that the DSD had degraded 'cos after all the extraction is done in a "DIY" setup rather than a professional studio. One thing to note though is that the 24/192 files I've downsampled/converted are even bigger than the original DSF/DFF files they came from.
 
As for a more generic thought on DSD, as I wrote in the NW-ZX1 thread, I wrote the following :-
 

Meanwhile about the topic of DSD, although I'm a huge DSD/SACD fan since 2000, I must say that it's not a necessity. It's definitely a nice to have & I even talked to some US vendors early last year to consider DSD support in their DAC Amps but it's not a must have. I've read in other forums where members who may not have experienced DSD shun a product cos it doesn't support DSD and I'm kinda disappointed to read that.

Note that DSD doesn't automatically mean better sound. To me, DSD just means it's closer to mastering. If mastering is bad, well you'll hear that bad mastering more easily or clearly. Also not all DSDs are from hires recordings. I've been told (although not substantiated yet) that there are times mastering is done at a lower quality (say 48kHz which is just above CD) to save storage space then later upsampled & converted to DSD format. Sadly I've not found an example of such a SACD yet. So personally I kinda trust old mastering instead - pre-digital days. If it's more modern digital mastering then Sony actually makes hires microphones for DSD mastering which I understand aren't commonly used yet.

IMHO, I actually don't think I'd expect to hear much diff between real-time converted DSD->PCM in the ZX1 vs a pre-converted DSD->hires PCM that's uploaded to the ZX1. This will depend on what the real time conversion is naturally. However, my pre-converted DSD->PCM 192/24 seem to result in bigger files than the original DSD files themselves!! So I welcome DSD support more to save space in my ZX1 instead.

 
I like to see DSD flourish in the audio world but I hope that it's more than just a buzzword and readers understand that DSD doesn't always mean "better".

Any chance you could share a snippet of one of those 24/192 files? 
I'm curious as to how the noise profile looks.

Tell me how to do it, I'll see what I can do. Do I use Audacity or some app like that?
