differing wire lengths to speakers

[devilkazuya]

when i was at a hi fi shop yesterday, they person who worked there was telling me that when i buy speakers from them, that i should buy an equal length of speaker wire for each speaker, even if in my room the amp would be to one side of the room, closer to one of the speakers.

He says that the one with the shorter length of wire would end up sounding better than the longer length, if i bought differing lengths, due to difference in impedence/resistance etc due to length of wire.

Is this true?

yeah, i think it is like £8 or £11 per metre or something. Should i buy from them (sevenoak)? or are there much better speaker wires out there that i could get for the same price or less?
