Not to be disagreeable, but I think the formula that Celtic66 gave you will not produce verey good results in a budget system. While it is true that nothing the source does not prduce can be reproduced by the speakers, the speakers are the musical instrument that must move air. They should I believe represent the single biggest expense. My fomula (until you get very high end) would be:
Speakers 40%
source 20%
amplification 30%
cables 10%
of course with a unit like the Linn Classik you would still be spending more on the unit (source + amplification) than on speakers. One of the great advantages to this path is that you can upgrade to match your speakers more progressively and with less of a one time investment than buying better speakers which are big, heavy and expensive.
