We've had them in store, but I've not had any of them at home in my own system. I think the main reason for that is that my own AV system has always been an AV system - its never really been compromised by a product that is good with music too. I've always felt that an AV product that has been designed for good 2-channel performance is usually compromised on the movie side of things. Of course, anyone's view on this will depend on expectations and any compromises they're willing to live with (and indeed ones interpretation of compromise).
The Arcam processors were always out of my price range, so we're never really a onside ration, although I did once own a Tag AV32R192, which I did buy because at the time it was touted as the ideal processor for music and movies, but it's music wasn't up there with the best, and it's not an option I've visited since. Because of how basic the 8200AP is, it has surprised me with movies - it may not be the most accurate processor, but im enjoying films, which is the main thing. But it's 2-channel performance is top notch, and suiting me more at the moment as I've been discovering a lot of music over the past year or so, and continuing to do so.
An SP3 would be nice 🙂
