Is going from Aerial 10T to Aerial 7T a significant upgrade ?


I have Aerial 10T speakers and I have been happy with them.
I've had them for 15 years and I guess I am ready for a change and since the speakers are in my Manhattan living room, I wouldn't mind a speaker that looks a little nicer.

My question is would switching to the newer Aerial 7T speaker be a significant upgrade in sound, or would the difference be subtle ?
 As my 10Ts are rather old (even though they work fine), I doubt I would get much for selling them so the switch would cost me about $5K or so.

I have Ayre CD player, ARC LS25 mk II pre-amp, and an ARC VT200 amplifier.

Thanks,

Love my 7b's as well, and they look great in my room without overpowering a room visually, plus the rosewood looks great. Never heard a set of 10t's, but I can only imagine how nice they sound. If it's a look thing, you could probably get a set of 7b's for what your 10t's would bring. There was a set of 7b's here recently for sale. Maybe try them first if you don't want to part with your money.

Thanks for the responses.
I'm really looking for an upgrade in sound (along with the aesthetics).
The main thing is the sound !!!

The 7T is different enough from the 10T that an audition is a must. For me it is much better except for deepest bass 
Thx - an audition for me is a bit of a problem.
I'm in Manhattan and the closest Aerial dealer is in Philadelphia.
