High jitter (from aggresive DSP ???)

I'd say this is still OK. You'd have to post a recording from a mic placed in front of the Reactor (say 50 cm) for us to check the problem. An UMIK-1 for example. It may still be easier to either borrow a Reactor or bring your speaker to a dealer... however, if it sounds OK on your big rig there is probably something wrong with the Reactor. In that case you should get in touch with Devialet support to get a replacement.
