The other interesting observation of the feedback so far is that it "removes the digital grunge", "spotify effect", "spitty and gritty" etc.

These are certainly not terms you would usually expect to hear/read (at least on this forum) when describing the SQ of 818/808v5 going into 7200 & 8000 DSP's.

Maybe these are all just relative terms and are only meaningful in the context of this additional box being layered on top of a very high baseline of performance.
