I just bought a 42" Samsung Widescreen TV, the sales rep (Futureshop) started picking the cables and stuff out for me without even asking for me towards the end, he picked up a $160.00 Component Monster Cable (4') I said you nuts man I'm not buying that He goes well this makes the most difference man don't buy the cheap stuff.....I said I'm not picking the cheap stuff but just mid-range,,,so I picked up the $45.00 CDN Monster Cable. Obviously our buddy works on commission and just wants a piece of the pie... I would'nt go get the $5.00 cables to hook up a dvd to a HDTV you get my drift. I once tried the high end stuff for my optical cable could'nt really tell the difference, now I know some of it depends on you system, but when youre spending maybe $5000.00 on just you amp than you could definately afford the 150.00 optical cable. But seriously does anyone really think there is a noticable difference between High End ($160.00 for 4') and Mid-range ($45.00 for 4') cable.
