Iʻd put together a SEAS Thor kit from Madisound ($2615.00). They have a number of cabinet makers who can build them and ship them to your door for a reasonable amount. Theyʻre not all that hard to build yourself. You could get help from a friend, or just have a local cabinet maker do them up.
The SEAS Thor kit uses the same tweeter and very similar SEAS Excel drivers to those used by the $14,000 Joseph Audio Perspective loudspeaker. Thor is a transmission line and will give you a good low end.
$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.
