I'm an ignorant American and don't have any idea how much 500 "lbs" is in USDs (where did you get that key for the symbol?), but Pabelson is right. I'd go for the best speakers you can find and look for used. This is a quite controversial subject - which component contributes the most to the sound of the system. I believe it's the speaker but the pre-amp, amp, source all make a big difference. However, I've auditioned speakers in my house that have driven me out the room. Have not had that experience with amps. Just found some that bore me, slightly irritate me, etc. Same with other items.
I'd find speakers first and then look for a receiver. Or better yet, find them as a synergistic couple. Or even better yet, find those two and the CD/SACD player as a trio. Damn this hobby...
