The following are what can happen when I use M8A to play CD wave files from a compute by foobar2000:

1. No click when playing wave files.
2. No click when playing wave files by upsampling to DSD128/DOP
3. click when playing wave files by upsampling to DSD256/DOP. It happens when the player changes from one track to the next and at the end of a wave file.
4. No click when playing wave files by upsampling to DSD512 except for the very weak click at the end of a wave file

Have you tried playing any very quiet tracks? Usually when I would experience a click/pop it would be on a very quiet track.

I think that maybe SMSL has confused some on the filter selections. All dacs have a filter. As I understand it, as years have passed, these filters have been updated to provide a better map for translating the digital signal to analog. Most dacs don't offer a selection of these filters as they simply use the latest and best filter. SMSL M8 has confused this by giving us a way to select what filter to use. Fast, Slow, and Mini. I've read that there are a couple of other filters in the works, the next one being 'Mini-Slow' iirc. The latest filter that's used on the M8 is the Mini.

Does this have auto shutdown after 10 minutes with no music playing and you have to turn it back on to play again? Can you disable the auto shut down?

I think it has this auto function and it can turned off.

The main reason I was asking this question that on the IFI iDSD the unit will shut down after 10 mins and then when music starts playing again I miss a few seconds of music. I wanted the DAC part and the RCA outputs always active without any delay.

I left mine on overnight and it did not turn off even when music was not playing.
Only the screen turns off after some seconds of not pressing the buttons.

perfect!

Yes you can turn off the weird auto shutdown feature. I forget how as I've only done it once but it's in the manual.

Any more commentary on how the DAC behaves when being sent upsampled-to-DSD512 music?

Thanks!
Jim

With M8A, I am using it to upsample all of CD wave files to DSD512. This makes music much more enjoyable than my previous DACs.

How can I do it on the Foobar 2000? Thanks!

How can I do it on the Foobar 2000? Thanks!

The following may be outdated already, but I hope it can provide you some guidelines.

One things is to use DSD not DSD/DOP because DSD/DOP cannot go beyond DSD256. Also, I think I posted this before, if so, my apology for reposting.

1. Download foo_input_sacd-0.9.11.zip from
https://sourceforge.net/projects/sacddecoder/files/foo_input_sacd/

2. Download ASIOProxyInstall-0.9.2.zip from
https://sourceforge.net/projects/sacddecoder/files/foo_dsd_asio/

3. Install "foo_input_sacd.fb2k-component" to Foobar

4. Run "ASIOProxyInstall-0.9.2.exe"

5. In Foobar2000,

File->Preferences->Output->ASIO->ASIO drivers

then double click "foo_dsd_asio" to show the "ASIO Proxy 0.92" window

6. Then, in ASIO Device drop down menu, choose the driver for your device

7. Then for each "Input" frequency or format, choose the desired

Output, Converter and DSD Mode

by clicking the - symbol in the corresponding column

For example, for Input with the frequency 44100, we can use

Output: DSD128
Converter: SDM type C
DSD Mode: DoP

This configuration can do DSD upsampling of CD wave files

For input with DSD128, we can use

Output: DSD128
Converter: SDM type C
DSD Mode: -

But up sampling is just upsampling... It can't create quality that isn't there.

 

[wwmhf]

You can try it to see there are any differences and whether you like those differences ...

I ended up buying a Sabaj Da3 that uses 2 of the same DAC chips as the M8A and ALSO has balanced output. All for $97 on Amazon.

Still listening to it but so far so good....very good.

Upsampling everything to 352.8khz PCM and then to 512DSD within Foobar.
