Allo Katana DAC

[Tim Curtis]

Hi everybody, best wishes for a productive and happy new year!

I received my Katana (SQ stage + isolator) on new year's eve and have been doing some burn in since then playing back a 4000 tracks playlist.
I also tried for the first time to play some DSD files (downloaded from http://www.2l.no/hires/) but all I 'm hearing is noise. Are there any specific settings in the Audio or MPD settings that I have to adjust?

In my case (same setup as yours) it works fine if you set the SoX Resampling (in the MPD config) to 176.4 KHz (any bitrate, 16/24/32).
The option DSD over PCM (DoP) can be on or off.

The 352.8 KHz sampling frequency also gives noise here.
One thing though: don't use the slider to go forward in the song, it doesn't always responds correctly. And give it a few seconds (2-5) to let the music start (I think buffers have to be filled first...)

It's a side effect of the Isolator board limiting the rate to 192K. DSD64 will work fine but DSD128 which requires 352.8K will just be noise.

You should be able to leave SoX off.
