Good to see that the firmware update has finally arrived! Bad to learn that it's apparently not a finished work. Many thanks to captblaze for taking point on this one. Sorry to hear about the gain problem, but like mbwilson111, the way I typically use the OPUS has me continually frustrated by the 10-second glitsch. Which is to say, I think I'll go ahead and install the damn thing and hope that medium gain (piped through my Magni3) is enough to handle my HE400i until the gain patch arrives. I'll drop back later to report on how the firmware is performing on my beloved OPUS #1.
