Best speaker cables for longer runs


I realize people like to keep their speaker cables short, but a redesign of my rack placement may necessitate runs of 20 feet or more. Any particular brands work well under such circumstances?

I have a theta dreadnaught ii and b&w 802d. Cost may be an issue as price does mount up.

I have used Canare 4S11 for 15 meter runs and it works very well. Neutral, easy to handle, and perfect for biwiring.
I have a pair of internally bi-wired MAS Signature Hybrid speaker cables that I would be interested in selling. Similar to Canare 4S11 in construction, but the conductors are made of a solid silver core wrapped by stranded OFC copper.

Very flexible.

Each run is 30 feet in length.

Pricing would be very reasonable.

I used them with a set-up of Von Schweikert VR4 Gen III HSE loudspeakers and VAC Phi 110/110 and Moscode 401HR amplifiers. The results were terrific.

Contact me for details if you're interested.
*I currently use Nordost Blue Heaven,.....But I would like to substitute something that won't sound worse.*

I bought a set of bi-wire 15 ft. DH Labs T-14's used for about $200. Very happy with them, at the very least they don't sound "worse" than Nordost Blue Heavens.

PS-you may pay thru the nose for long runs of name-brand cables new. Used, the price can drop drastically.....
