Late answer, sorry...
I gave up on trying to upload my photo and video files, the Genelec app kept on returning the same message (error 401). I think my 1-year free trial period is over anyway.
Several tries later, I still can't upload the video on the Aural ID app which returns me a "401 Forbidden" error. Genelec support told me that they had a server side issue and they fixed it, but the file transfer still doesn't work for me.
I had the pleasure to meet Max and listen to the M1 last summer in Berlin, it was a wondeful experience!
Can't wait to book a demo of the bigger model next year when I visit my family here again.
You'll be perfectly happy with a pair of 8350s, stepping up to the 8351s like I did will only give you a marginal gain in sound quality, far from 2x better compared to the price difference. Otoh my white 8351s look so much better...
In my experience the 8350 model is one of the best bargain...
