$3500 floor standing speakers used. What would be your choice ?

Just saw some Tannoy on TMR today.  Real close to your original 3500. Nice cabinet

Open baffles open and relaxed if you have room.  Won't be a problem driving them.

Many speakers take too much power.  

+1 for Totem.   Tremendous value and all around excellent speakers.   Super easy to drive.   Might look at the Bison Towers or similar.

The OP’s description in his second post says ProAc just like his initial post. Just make sure you get enough juice from your tube amp.

Ha… I just spent that this week (but CDN not USD) on a used pair of speakers. Probably not your cup of tea though… Coincident Total Victory but I have desired these for a long time, saw an opportunity and decided I should just indulge. Good Luck with your quest…

As I mentioned, there is no rush at all. In fact, if I could find Michael Green Audio's top Chameleon speakers, that would be great. They are impossible to find.

Besides, I usually start threads not only for myself to get advice and suggestions, I try to initiate interesting and helpful discussion on a variety of audiophile subjects.

But no one so far describes the sound of their recommended speakers.
