I've not heard your speakers, but have heard a 9090DB through Tannoy Reds and would recommend, as others have, that you test drive a few other amps with your VS speakers before going back the drawing board. Receivers offer convenience but are always a compromise. Perhaps use REW software, a microphone, and laptop to see where the trouble spots may be with the room. They'll be there regardless of the amp.
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
