Thanks @David_Gibson . But since there is no USB, it’s not controlable from Roon, right?
Anyhow: I’ve found on this forum, that Pro-Ject Pre Box S2 Digital Pro-Ject Pre Box S2 Digital - Volume Control - #4 by dabassgoesboomboom can obviously do it, but according to Review and Measurements of Pro-Ject Pre Box S2 Digital | Audio Science Review (ASR) Forum it has a good DAC, but a not so good Amp.
Also my current Audiolab M-DAC can do it, but that’s the one I wanted to replace.
Are there really no other devices?
