I just got back from a long-ish trip and decided to throw caution to the wind and try the firmware upgrade via USB (it didn't work). Fortunately, I had a serial cable and my notebook seems to be one of the dying breed with a functioning serial port. Using the serial port, it updated just fine.

I get the same error on the autocalibration. It claims my rears are large and my mains are small and suggests I switch them. You'd think someone would have stumbled on that bug during testing...

Otherwise, the upgrade went without a hitch. I'm going to have to get around to calibrating things manually with a sound pressure meter.

In spite of those nuissance items, the bass management does seem to be a lot better now.

Perhaps they'll release a firmware fix for the new firmware so that autocalibrate will work again and USB upgrading will work properly.

I'll play with it over the next few days and see how things go.

Cheers,
