If you are looking at the Vandersteen treos, I’d suggest you listen to the Vandersteen Quatro CT’s. Which have better bass and great self amped subs in them already. I think you can find for &14,000 used. Which is a bargain.
speaker upgrade fever
I'm considering a speaker upgrade to compliment my Aesthetix Mimas integrated. Currently, I've got KEF Ref 1 monitors paired with (2) REL S/3 subs. Must stay away from bright, analytical and clinical presentation. Room size 12'x19'. Music is jazz, acoustic Americana, Chamber, symphonic etc.
Looking at the ProAc K1, Triangle Duetto and the DeVore o/baby. Also, a huge departure, Vandersteen Treo CT, floor standers. I understand Vandersteen pairs well with the Mimas.
Always open to suggestions, happy to buy quality used and demo.
Budget, ~$8-$11K
