You've got lots of choices in the $3-6k price range for speakers. The Virgos(haven't heard new version yet) and GPs are certainly great speakers, but others in that range would probably do better on the low end might be the Gershmann Avant Garde RX20, Coincident Technology Super Eclipse, Soliloquy 6.3, Talon Peregrine, and Silverline Sonata II. All are excellent speakers(as are the Virgos and the GPs), and personal preference more than anything would likely determine the winner and fairly easily as they're all very different. If you're looking to do a CD/SACD player that cheap I'd buy one and get it modified by Stan Warren/Dan Wright/Ric Schultz so it does justice to your speakers(and the rest of your system). Best of luck.
