Any Octave Owners out there?

I am currently doing a demo of the V40se w/ BB but thinking about the V80se. I notice there’s not much posted and wondered about the sonic difference between these two. How is the reliability of these? Why haven’t there been any upgrades since the release of this back in 2017? I was thinking about the Raven Osprey but had an opportunity to try this in house with my Spatial M3 Sapphires.
Appreciate your input.
I rarely adjust the bias.  Maybe every two months and I use mine a lot for music, television, and movies(HT bypass).   I would get the super black box as well at some point if you can.  That takes the v80se to a whole other level in regards to bass and imaging.
Any thoughts on the new V70 Class A, I'm not to familiar with the technology behind it but Andreas was very excited about the new release.
I don’t have any experience with that one.
