I have it on my T758v3. That unit can store up to 3 different profiles, so I use one calibrated for single seat 5.1.2 movie watching, one for wide area 5.1.2, and one for single seat 2.1 music listening. I can toggle between them with the remote in an instant.
None of the other two I mentioned can do that.
Sometime this year after I remodel my office, I'm going to get one of the M10 integrated amp/streamers and use it with my LS50/Kube10b 2.1 music setup.
