One further thought, Ariaudio.
You don't want to make a lateral move, and you've got a budget of around 2-2.5k. But the speakers you own, the Stradas, are very good at that pricepoint, and you've got a sub to compensate for their main weakness. Give the quality of your current set up, and your target price, I think you'd have to get pretty lucky to make anything but a lateral move. You could certainly get a *different* sound that you like better, or improvent in a particular respect, but obvious, all around, improvement will be harder to come by.
I think you'd be well served by patience, and careful watching of the used market: your budget get's you into speakers with north of 5k MSRP, and that presents a wealth of options. Even this way, pretty hard to beat what you've got, but definitely more likely, and you'll have fun shopping.
