With a $1.5k budget, I recommend that you look for speakers that cost around $1k, and keep the receiver at about $500. Speakers affect the sound much, much more than the receiver. In fact, if your budget goes higher, I still recommend keeping the budget for the receiver close to $500, until you get to multi-thousand dollar speakers. And even then, you probably do not need to spend much more on the receiver.
As for your question regarding those speakers, just about any receiver you can find will be compatible with them.
I recommend that you go out into the world and listen to as many speakers, and as many types of speakers (e.g., ribbon, horn, dome, whatever) as you can afford. There is no such thing as a perfect speaker, so it is always a question of what virtues you require and what vices you can tolerate.
And remember, when they come out with some new sound format, quality speakers do not need to be upgraded; it is only the processor and such things that need to be upgraded, so money put into speakers is a better investment than money put into a receiver.
