The Allo's DigiOne reclocks the signal and that’s a reaon why it (could) sound different, of course the diffent power supply could also a reason.

The influence of the analoge PSU is smaller in digital as in analogue as a basic influence.

The reclocing generate different jitter as any reclock do...
So maybe you hear that differences as an "advantage" means airy.
Thats all possibilties.

The difference from the Roon/Tidal stream could be that Meridian is not a Roon-ready device but I have no knowledge here.

Have you tried to use the SL output from the 218 or only tried the RCA output ?

Please tell more about the hardware and wiring of your RasberryAllo's DigiOne and how it’s then fed to your audio.
