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

Buying a speaker without auditioning is tough, trying to figure out how it “sounds” by the “words” of others.

Maybe look at what speakers others are using with the OP’s amp.  Otherwise it’s compile a list of speakers compatible with the amps power then choosing

Good luck, hoping you’ll land on something good

Thank you.

ProAc 3.8 is within this price range. Would they match well with my amp ? I have no idea.

+1 on the Spatial Audio Lab X3s open baffle used. Great speaker that works well in many different set ups. Easy to drive. 

B&W Nautilus  803, bass is tight and the speaker is warm sounding. Not forward or brigjht sounding with no fatigue.

My preferences are several I currently own like my mains PMC, small garage system Totem, and den system Sonus Faber ,but have quite of bit more power driving them than the 60 watts per channel so that might be a problem.

I rotate a pair Monitor Audio also but they are a little bright imo, a small pair of NHT's that still sound good. Had Dynaudio but to me were finicky somewhat so got rid of them and the KEF's were a little bright.

Don't like horn speakers at all and sure don't like the looks of Tekton but have never heard them.

If I was looking again the Devore's would be on a my list, ATC, different Totem's, always been a fan of English Speakers for some reason. Good luck
