If I wanted to make my own speaker cables, is this a good choice for wire?

Duelund DCA12GA bare between Luxman 509X and ATC SCM 20 monitors set on Sound Anchor stands and they are superb.  Solid bass, sweet midrange and very open on the top end.  This is a perfect speaker wire for the money.  Perhaps my Decware Silver Stix are a bit better, but for the money Duelund is tough to beat.  Have fun with your choice.

Anyone have any thoughts on Belden 9497 vs Dueland? Oil soaked cotton seems like a perfect fire hazard, lol, also might attract insects. 

Marty I have my office fumigated monthly to keep the infestation of insects at bay and so far only two fires this year so far ,,,,

😆 seriously though i dont understand the benefit of cotton over pvc like in belden 9497, though it is prettier in a retro WE kind of way. 

I have two pairs of DIY speaker cables.

One is Belden Studio 814 and another is Nanotec Golden Strada #79 MKII.

Both are models unique to Japanese domestic market, but my local Belden dealer does carry it, so you might want to check with your local dealer first.

Studio 814 and 717EX are extremely popular with DIYers in Japan and I could see why. 814 is a romantic sounding cable, adds a lot of weight and dynamics, and just the right amount of warmth. Very effective especially with smaller bookshelves. I am currently using #79 MKII in tandem with Soundstring Gen1 Tricormaxial cables in my main system (I am running a high input/output setup with a sub). The Nanotec is probably as good as it gets for its price. Very spacious, musical, and neutral sounding. But it seems like you could only purchase this in Japan, though you might try your luck with their Taiwan dealer on Facebook.
