Well, I just upgraded my model 9 signature 3 to a model 10 for a chunk of change. Unfortunately, my original amplifier is out for repair, so I am unable to yet do a fair comparison. With my substitute amplifier, I would have preferred the 9 signature version 3 to the 10 by a mile. I will post further thoughts on this when my original amplifier comes back in order to make it a fair comparison. I have also written muse to discuss this with them as at present the sound difference is huge and not in a positive way. My wife confirmed my findings to her ears, which are of course better than mine.
Cheers - Scott
