ROCK on Holo Audio May L2 and "limitation" in sample rate

[Dario]

Hello,

I’m using a Holo May L2 (via USB) which is rated for 1.5Mhz of sample rate. ROCK see this unit until 768Khz max. HQPlayer push the May until 1.5Mhz without any problem. Is there a reason for this limitation under ROCK? The same happens on roon server running on mac, obviously.

Many thanks, bye

Hi there.
I believe 768 is the max rate that Roon RAAT supports.

You could instead set Roon to convert your source material to DSD256. That will require more Roon core processing, which may stress your core machine. But in my experience, the May performs extremely well with DSD256 conversion (although that experience is with HQPlayer DSP rather than Roon DSP). In your situation, I’d experiment with that option rather than very high PCM rates.

It’s a feature request:

1.536mhz PCM / DSD1024 support

Currently Roon is only able to play files or output up to 768khz PCM or DSD512. In Roon’s built in upsampling, the max rate is 768khz. And if you put a 1.536mhz WAV or DSD1024 file in your library (created by a tool like PGGB or HQPlayer Pro), roon simply does not recognise/add it. So you are not able to play these files with Roon and must use a different player like Foobar or HQPlayer. There are a few DACs like the Holo Audio or Denafrips lineup that allow for 1.536mhz or DSD1024 input, most…
