I’m not sure I’m understanding where you’re going here- I had a quick look at the Aries G2 manual (couldn’t find for G1) and the only mention of “upsampling” had to do with streaming MQA files. Apparently there is a setting that will employ this action during the “unfold”.
As for passing files through I don’t believe this unit “upsamples” PCM native 16 bit to 32 but rather “supports 32 bit files” when output via USB. The standard SPDIF formats (coax,Toslink and AES) support up to the standard 24/192.
Either way- not sure how your planning on configuring your NAS storage drives or if you’re streaming across a network from another ripper/playback unit but I would always rip the music in its native format.
If I remember correctly the Soekris will not upsample and will accept files up to 24/192. I’ve no experience with Chord but I believe some of their units will upsample- just not sure if the Qutest will or not.
