Aerial 5T impressions

I know this thread has been inactive for a few years but it seems the 5T is still a current model. I'm curious if anyone has ever listened to the 5T and also listened to the Usher Dancer Mini-X DMD. That's what I'm using now in a 9 ft by 12 ft room with an ATC P1 Pro amp. With both having a front slot port maybe they're quite similar. If the 5T is a significant upgrade I might try to find a pre-owned set

I posted back in 2017 that I bought a pair of 5T's. I've upgraded my amp to a Bryston 3B cube added a Luxman CL38Use preamp and a JL Audio D-110 but my 5T's have remained in the system. They produce great music. 

Did you have other speakers in your system prior to the 5T's, if yes what were they please? Also how big is your room and how close are your speakers to the rear wall? Thanks

Room is 12 ft wide and 18 ft long. Speakers are 2 ft from the long front wall and 8 ft from my listening position. Prior to that I had an original pair of Aerial 6B's which were front ported. 

Okay thank you very much
