The $5000.00 Complete System Challenge

I agree on the integrated amp vs separates in this price range. I would spend about 1K on cd, 1.5-2K on integrated amp, and 2-2.5K on speakers. If you are willing to sacrifice the lowest octives, you are going to get better sound per dollar out of stand mount speaker's, although the Maggie's suggested above are a great audio bargain. All suggestions are just rule of thumb, and most rules can and should be broken in pursuit of better sound.

Questions about your space, taste and current amplifier are critical.

Rega and Quad ideas are excellent.

Before going all in for speakers, here are some suggestions for a balanced system within your budget.
