In the old days, most people thought you should put the most money in the speakers. Then came along the new audiophile who re-thought this proposition. Now, many advocate putting a large portion of your budget into the amplication or the front end. I personally don't think of percentages because with so much gear I get bogged down. I have a pair of mono tube amps, a tube line stage preamp, tube phono preamp, reel to reel, cassette deck(yes, I still use it), tuner, sub-woofer, turntable, etc. So just buy what you like and it will work itself out.
