Speaker Cable to pair with Soliloquy 5.3's

I use cobalt cables and am pleased with the result. I also like the lifetime no questions asked replacement guarantee that cobalt has and that I have used ( one of the ends bent).

Internally, sols use Oval Plus wiring so perhaps matching with the same speaker cable makes sense.

I think Rysa4 meant to say that Soliloquy uses Analysis Plus wiring.
They are excellent with Signal Cable shotgun bi-wire. I've also found them to work well with Analysis Plus Silver Oval, though if you have a SS system, I'd probably stick with copper.
All the best,

If your 5.3s are new, wait for at least 300 hours (preferably 500 hours) before you start evaluating cables for them. Soliloquy speakers are notorious for a long break-in period. (I know. I have 6.5s.)

In my experience, bi-wiring is definitely beneficial. I use Kimber Bi-focal XL. Also place them well out from the wall behind them - at least 4 feet.

Boa,

What Signal cable are you referring to? The standard or Ultra? IC's as well, or speaker cable only? Current IC's are AP Copper Oval's (only 1, I have an integrated amp) and only a CDP.

With the Sol's, I would suggest using the Ultra shotgun bi-wire, unless your room forces you to sit less than 6 or 7 feet from the speaker. Or simply treat the room appropriately. Because when bi-wired, the Sol's project exceptionally well, and a small or untreated room will compromise the bi-wired sound. With a single wire on the Sol's, they sound more laid back, in my experience. I've owned the 5.3 and the 6.2

Also, as Nighthawk said, wait AT LEAST 300 hours before evaluating cables. The bi-wires will make those things sound like a megaphone until the speakers (and consequently, the bass) break in.
They are fantastic speakers, once broken in.
All the best,
Howard
