hiya chris yes there`s a huge difference in price between ls-80 and odyssey. i used the odyssey back in 2009 when i had an integrated tube amplifier i got from china and used a musical fidelity nu vista cd player and quad 12L2 speakers. i used chord anthem interconnects. that combination was gorgeous sounding. open sounding. for the system i have now i always intended to splash out on all the cables but took some saving up so i went back to the odyssey cables along with a pair of epic cables to use on bass duty just as a temporary measure. unfortunately they weren`t suited to the system i have now. the top end was a bit on the bright side. in the right set up i think the chords are really wonderful. they`re the only ones i ever tried. you can check out the prices on the abcaudio website for the ls-80, they have other speaker cables in the ewa range too. by all accounts on everything i`ve read on the ls-25 and ls-40 they`re all very good and like i say i had very good results using the chord odyssey cables. i think if your system is on the brightside then maybe the odyssey`s maybe too much of a good thing but in a warmer sounding system the odysseys are lovely. you can pick them up on ebay for a good price secondhand. i hope that helped
