I'm thinking about upgrading my amplifier and speakers, butI haven't got the faintest clue as to what is good/worth the money.

It'll mainly be used for my record player (project debut) and less often for my iPod.

My budget probably won't be huge, but in the same way that the project debut is a great turntable 'for the money', what is the best I can get on a low to mid budget?
