integrated amp with phone for graham ls6 under $4000 new

What do you mean “the ones I’ve seen?”  How long do you need?  Personally, I would just start with Belden 12 from Blue Jeans cables and listen for a few months until everything breaks in. Then you can try something else to see if you like it better. 

i meant when looking at wires for sale, most say 3.5mm or 5mm. i wasn’t sure if there was a danger of damaging amp or speaker if using the wrong type or wrong length, is there? currently i have about 6 feet each from my old amp to each speaker  of this cheap wire “wire path bulk wire by snap pan speaker14awg 2c 105 strand oxygen free copper”. would that work for the time being or think i should get the blue jeans?

The measurements you list are in “mm” not meters, so I would say they are in reference to the size of the binding post a spade lug fits, thus does the speaker binding post measure 3.5 or 5mm in diameter.  Wrong size spade lugs = a big problem.

guess i listed it wrong, these are the ones i was looking at “LFD Spiroflex Speaker Wire Pair 5 meters” but they’re $675 and i’d rather start with my cheap ones listed above if it will sound “okay” and not cause any damage to the speaker or amp

Here ya go! The cable you are using will not damage the speaker or amp!
