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.
$3500 floor standing speakers used. What would be your choice ?
My speakers are 25 years old, working fine for now, but who knows I might have to replace them at some point in the future.
The amp would be VAC Avatar SE 60 watt/ch all tube with onboard phono stage. Nottingham Analogue Spacedeck/Spacearm turntable and couple of tape decks.
I am thinking Proac maybe or whatever.
