Playing 24-192 files with Sonic Frontiers SFD2 Mk2

Hello

I got a Sonic Frontiers SFD2 MK2. Presently, I'm listening music by Qobuz in my Melco N1z 6T connected to an Aufio gd DI-20 interface with the USB yo SPDIF of an Aqua LaVoce Dac.
I simply love the old SFD2 which was refurbished but I can only listen 16/ 44-48 kHz files
I can't select the sampling rate with the interface,
Question:
If I use a chip like the WM8805 to replace the Ultraanalog SPDIF receiver in the SFD2, will I hear high resolution files with this dac truncated to 44 -48 kHz or the Ultraanalog chips which goes to 48 kHz will not let files over 44-48 kHz play ?

Any other solutions ?

Thanks
 
Yes, I know but my goal is not playing files over 24/48, I just want playing 24/96 and 24/192 limited to 24/48.
As is, 24/96 and 24/192 don't play at all with this dac. So if the receiver can do 24/192, will hi Rez files play and be limited to 24/48 by the HDCD chip ?
 
No. The PMD100 tops out at 55 kHz.
Any choice you make will, potentially, alter the sound of the dac. Your could precede the PMD100 with a sample rate converter which will convert any input sample rate to a fixed output sample rate chosen by you. The other choice is to replace the PMD100 with a 96k/192k capable digital filter.

Sample rate converter seems the easy way to do this task. I really don't know anything about this. Is there any serious SC so I will not affect the sound quality ? In fact, most of the files I have (4T) are 16/44 and half of the Qobuz files I have are also 16/44. Listening 16/44 files on the SFD2 Mk2 gives me more pleasure than listening them on my Aqua LaVoce S3.

Hello Tonixp
Great. Now where can I find the SPDIF module to replace the AES21 module ?
I could perhaps use I2s to bypass SPDIF module.
1) The socket uses very high quality parts, the best that I have found on the market for every SMD/TH parts.
For the wm8804 ic , I order genuine parts from a reputable vendor (they are of course expensive).
The resultate is very nice!


But the problem now is that I don't have ago the equipment to test the new sockets because the Parasound DAC 2000 it come back to Holland .
So as soon as i can , i will come back on this item for project also a check control quality pcb .
Please stay tuned .
2) Yes you can also bypass the spdf module but you need a 4 wire PCM format signal.

DATA LEFT
DATA RIGHT
Also a RJ45 or HDMI connector fixed on rear panel and a appropriate source by the way.
 
The most problem of i2s unbalanced trasporto Is the lengh of cable (max 30 cm).
So :
1)you have to continue to use balanced type.
2) you have to convert in pcm format and bypassing digital filter you will obtain the max bit and sampling rate performances of AD20400 that i don't know.
 
This will depend on which DAC chip is present inside (i don't know) the AD20400 and consequently on its technical specifications.
For example, the TDA1541, although implemented in 99% of cases in I2S mode and coupled with its SAA7220 filter, cannot work beyond 16bit/44.1khz, but things change if you set it in SIM and NOS mode, in this case it can work easily at 24bit/192Khz.
For more info about AD20400 you can see relative THD.
 
Today, I listened again 16/44 files on the SFD2 MK2 and on the Aqua LaVoce S3. For my taste, the SFD2 MK2 wins the contest. I love it so much I could forget listening hi-Rez files and listening them at 16/44 on the SFD2.
The SFD2 has more 'Meat' timbre. Sound simply has more real life. If I could find something I only have to transform files instead of modifying the dac it could be great.
 
The Primare NP5 Mk2 will sample rate convert.
The old MK1 is around for about half the price of a Mk2.
There is also the Mutec3+USB but I am not certain about it's capabilities.
There other external options but none are straightforward.
