Yeah, that's very much in line with what I've found with sinc-M as well.
As far as deciding to move on from HQP to Mscaler, that just makes good sense in your position. You would need a compelling a reason to keep pushing. My reasons are my own. I don't mind the financial investment for better sound, but I have a penchant for elegant technology. The DAVE is elegant tech. DAC, preamp, headphone amp in a ridiculously compact unit. I use it with headphones, but eventually I'll add in some super efficient speakers like the Omega Super Alnico. This will mean no headphone amp, no power amp, just the DAVE.
It is worth effort for me to try ad keep this minimalist setup. Upscaling in software meant no additional hardware. If I end up going Mscaler (not out of the question at all). I will also be looking at a connection like Opto-DX. All of a sudden that's six more boxes including the power supplies, then there's the clutter of interconnects and cables. Right now the Dave sits on its own tiny shelf attached to my laptop stand. It's so nice that way.
I’m just using my setup purely for headphones, Focal Utopia. I also won’t be getting an Opto-DX for the reasons you stated. Too much mess. I might look into Wave cables next year. Right now sounds excellent with just some cheap Blue Jeans bcn cables and stock power supply. I’m sure things can improve further but think all this talk of RFI might be overblown. Seems like the final tweak but not a must have.
