Two suggestions. Both will work very well.
Canare 4S11 Starquad. This runs about $1.20/foot. So, $60 for a 25 foot pair.
MAS Reference Hybrid. About $800 for a 25 foot pair.
Both have four conductors, so they can be used in a bi-wire configuration.
I have used both with VonSchweikert VR4 Gen III HSE. They're both good. The MAS is better.
If you're interested in a used pair of MAS that are unterminated (a little under 30 feet), then send me an email.
