I haven't heard the Wavelength Brick but I own the Wavelength Proton and love it, I'm sure the Brick is even nicer.
I've also gotten to audition the Ayre QB-9 which also uses the Wavelength Asynchrous technology and was blown away. You may be able to pick up the Ayre used on the high end of your budget, but I'm not sure what they normally go for.
