Given how my 568.2mm is a bit temperamental (it seems to work fine most of the time, then for no good reason can flash "Bad software" at me when switched on and need turning off and on a few times, if not a reflash) I think this is a very retrograde step.

My nearest M dealer is literally a 5 minute walk, but sadly they're not a premium dealer, and far more interested in flogging me Naim as the solution. I suspect that reflashing firmware is not going to be in their repertoire.

Sooloos, Roon, G series (with LPS upgrade), 800 series (with LPS upgrade), HD621, AC200, Prime and PS, DSPs old and new.

Purdeys, Moke, Leica, 'Blad. Only the best.
