I believe you can update to a specific FW if you can get a copy, and put it on the SD card. But only to a later(not earlier) version, and leaving the WIFI off.Listened a bit more to some orchestral tracks and piano instrumentals.. Still in the honeymoon period but Geez the string timbre and decay is on a whole different level! Even the double bass sounds "different" with more body to it. I'm literally hearing new layers from old song libraries.. with the same Z1R.. how to explain that?! And this is with Direct Source on, no sound mods yet..
On the other hand, walked to work with Goldie in my pocket with the leather case.. wow, no picnic huh? Not too heavy but it's quite noticeable.
BTW, what is the best FW version for SQ (V-shaped, layering, soundstaging)? Mine came in with 1.03 installed and pondering whether to update directly to 1.08 or is there option to update to intermediate FW version e.g. 1.07 instead of latest?
I'm not aware of where to download the FW. On previous models, people had identified where the various FW for a particular model were stored.
