Yeap I can hear it. I find it interesting that with increase of DSD frequency , noise increases.

Your CLK line and your DATALR lines ...do they run in parallel ? At what distance are they.

This is the noise of the Chinese non-balanced version.
My versions are balanced and this noise is not there.

OK that makes sense. The Chinese boards might have some other issues , hard to say since they don't publish the schematics .

Is the volume of music is adjustable by Signalyst HQ player or an atenuator is required?

HQ Player has a volume control option.

Is that's mean DSC1 is compatible with HQ player volume control?
Thanx

In Linux, HQPlayer can precisely adjust the volume through ALSA. On Windows did not check.

Worked for me in Win10 too with my earlier NoDac projects.

Today I've been listening to one of ppy's DSC2 boards.

I've temporarily assembled the DSC2/Amanero onto an old aluminium base and I'm feeding it with some TPS7A4700 power supply modules. DSD256 data into the Amanero (firmware version 2003) is courtesy of HQ Player, upsampling CD quality FLAC rips and routed via an HQ Player NAA.

The sound is outstandingly good; rich and very detailed, kind of natural/organic. My partner is a musician but pretty ambivalent about my 'tinkering' but the sound immediately caught her attention and she was soon asking me to put various tracks on; we spent several hours just going through the music library.

Did I mention that there is no extraneous noise too, nor any of the pops/clicks that can affect this sort of DSD replay.

A great job ppy - thanks.
