Speaker Cable Recommendation

OP,

Hard to beat AntiCables 3.1 ($250 6 foot pair) or 4.2 Flex ($460 6 foot pair) speaker cables for the money. Just remember that the 3.1s take at least 150 hours to settle in, and the 4.2s at least 100 hours. I haven't completed testing, but the Zavfino Nova OCC cables ($390 2.5 meter pair) and Morrow Audio SP6 ($550 2 meter pair on sale) are very promising.....will complete a shootout next year when my listening room is completed. Also I would have NO problem using the Micca speaker cables in a second system.....silly good for $40 per pair.

The OP asked for a cable for high efficiency, low current cables. There is really no point in proposing arm thick, high capacitance cables with lots of skin effect. My two bits worth…

Like you I have a low power, high efficiency system, with fully horn loaded speakers. After playing with various cables including Duelund, which I found charming but ultimately too colored for my taste, I’ve now found audio nirvana with some "Chinese Valhalla" (in truth a chinese copy of Nordost heimdall). There are no logos or fake branding but the cable seems identical.

They are the best cables I’ve owned: not thin at all, nor bright (and my system is on the bright / upfront side so I should know!) but very dynamic, transparent, and wide open (imaging is fabulous)

It’s been compared by others to entry level Nordost stuff and is better, doesn’t have the "thin and bright" character at all. In fact I find it buttery smooth!

Iconoclast are the best bargain for the price and get completely out of the way. And they have a 30 day money back if you dont like them.
