Found a great deal on speaker wire. A 15' pair is on sale right now for almost $10k.

In all seriousness can speaker wire make that much of a difference in sound quality?

Rebulx, try this. Remove one speaker cable from your M100s. Plug that into a potato. Take another speaker cable and connect it from the potato to the speaker.

Then try a banana.

What do you like better? Veggie, banana or plain? Can you even tell the difference?

As long as the resistance of the wire run is much less then the nominal impedance of the speaker I’d say no. I’d doubt that you’d notice a difference between that $10k pair and 15’ of pure copper 10 or even 12 AWG wire.

Big fan of Belden bulk cable.

I'll just stick with my OFC 10awg speaker wire. 1/100th the cost of that wire and I can guarantee there is no audible difference.

I can remember the potato experiment from middle school.

lol! I love the potato experiment! good times! I saw that and just HAD to post it! I guess if you're a prince in Dubai... you know.
