I would assemble a completely new system. Yes, first choose the speakers. $15k is not little, especially if you buy used pieces, at least some of them.
Should speakers be upgraded before preamp and amplifiers?
On a two year plan to upgrade my system. Wanting opinions on what to do first, looking to spend $10-15k, listening room 14x 30 x 8. Currently have Von Schweikert VR-2 speakers Sansui 9090db receiver Pioneer PL-a35 turntable. Would like to try a system with tube preamp. Thanks
