Some advice please on an amp upgrade for someone who has not looked at a Hi Fi mag for 20 years. I have a Linn LP12 'anniversary' with Akito arm and K9 cartridge (a significant birthday present from my wife), Musical Fidelity B200 integrated amp, and Musical Fidelity MC2 speakers. I have always been more into the software side than hardware yet I'm now thinking my system could be better but I'd prefer to spend money on best buys from three/ five years ago than on new equipment. I'm still playing and buying vinyl - jazz to dance to world music. The question is is the amp the best place to start and if so what would people recommend I trawl e-bay for? Budget £300 to £600, not worried by 'styling', used to have a soft spot for Musical Fidelity but not sure how they are rated now, would consider integrated or pre+power.
