Hey, Kerry,
I used to live on the Upper East Side in another life (504 E 81st studio apt) when I was a fellow at MSKCC. I've had Quads for years, even managed to squeeze them into the studio apt with a Hartley subwoofer, but my HT set-up has used Tannoy System 8 NFM II speakers which are stand mounted and reasonable size. Needs a subwoofer though as they only go down to about 55 Hz. A bit industrial looking with gray matte cabinets and black grilles, as they were designed as studio monitors, but sound pretty good. The late JGH used System 10 DMT II monitors in a 5.1 system for a number of years, which is what I have now, but with an 8 as a center speaker - I still have a pair of 8s sitting around, but w/o grilles. I think the 10s may have been his last system. They are obsolete but show up from time to time on ebay within your budget.
