Oh I forgot to say but yeah I also use HQP NAA (Ropieee XL). I used an Allo Digione Signature before, but it could only output 384kHz out of its singular bnc. I went with a regular Rpi4, replaced the PSU with an iFi iPowerX, and I’ve got a good streamer with excellent isolation from my m1 mini’s computer noise. Threw an ISO Regen into the mix because why the heck not.I've done more or less the same as yourself. I did have an MScaler for 18 months but preferred HQP once it wasn't connected directly to the DAC. I use an OpticalRendu as a HQP NAA for the Mac mini M1 HQP server.
Unlike the MScaler, this means it's separated from the DAC by Fibre Optics preventing electrical noise from the hardware and the processing of the files. The server is available to more than one DAC in the house. With an MScaler, I'd have to move it around with me but the Mac mini can send the data to any endpoint connected to a DAC.
As you mentioned, it's nice that it receives regular updates.
M Scaler is great, no questions about it. I’m not sure how future-proof it is, and there are equal (many say better) alternatives.
