It's been done - and you could spend the rest of the day Googling for the various references. There's an older story where Quad has reportedly demo'd their gear using Black & Decker extension cords to connect to the speakers, etc. Audioholics has a bunch of articles, or Google Roger Russell (of McIntosh fame - try Roger-Russell.com, I think) and get more answers there. Bottom line is that it's all wire - some has better insulation, some is thicker, but if it's 12AWG or better you should be good to go (as I pull on the fire-retardant suit... ;~).
Converting Power Cords into Speaker Cables?
Someone very knowledgeable in high end audio swears that instead of buying more expensive speaker cables, it's more cost effective to look for power cords of the same cable and use it as speaker wires. He has very successfully done this with Vahalla power cord and found no sonic difference between the original Vahalla speaker cables and one he made from Vahalla power cord. He is now applying his creativity to other brands. The advantage is considerable cost savings but downside is when you want to sell these reconverted cables. Your views are appreciated. Anyone tried this trick? Any technical/cable geometry flaws in doing this?
