2nd the Paradigm Founders. Really great speakers. Play well with tubes or ss. I have the 120h. Currently paired with a pass xa30.5 and tube preamp they are amazing. Also had them with an EL34 integrated and also very very good. You can find the 100f in your range for sure or the 120h for 4kish used if you look around.
$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.
