Thank you 3351 for your reply. Yes I thought that firmware update could not be a problem, but.... you know, this is my new audio unit (expensive for me.....) and I keep attention! Unfortunately I found any info in its good manual. So, are this update really useful for you? Are they introducing new or modified function or is there just any bugfix? What is your experience with MKII? After using this MK3 I believe this is a very very good audio unit!!! I come from Echo Audio Layla24 (not so bad), but this is another world!!!
Thank you again.
