Is it worth buying and amp and 2 bookcase speakers over a 2.1 computer speakers like the ageo? budget is limited tbh so it would be the lower range if i was to buy an amp and bookcase. i mainly use them for music as for games i use headphones movies are also a consideration but i can use my headphones. also if i were to buy an amp can sumone recommend some amps to look at which contain a optical in and some budget speakers...i will want a reasonable sound quality and the capability of turning it up load occationaly. also can someone point me in the direction of a good review site for speakers both for computer 2.1 speakers and amps/bookcase.
