I’ve had the III-T for a few weeks now and I remain highly impressed. As a longtime user, that makes me happy. The best does, indeed, get better.
I’ve also read a lot of comments here from folks who haven’t seen a reason to upgrade, and I think that’s really smart. If you're good with the one you have, you’re good. Don’t let someone else decide what you need. Well done.
Personally, I like seeing people still using Standards and Ultras. Killer boxes that blew everyone’s minds not too many years back, and they still sound good. I’m very satisfied with the new Starship of the Fleet, yet I completely get those who are enjoying the model they have.
