I am happily using my PWD MKII incl. bridge for more than 2 years now, but I never upgraded from firmware 2.2.0 to a higher level. Could you please let me know what I can expect from the different updates in terms of sound reproduction. The process as such is clear to me how to do the upgrade, but I simply don’t know what it will do to the sound. My bridge already works with the latest software update as it came in automatically. Would be grateful for your advice!
