Bi-wire Silver Oval Lets Your Amp "Open Up and Sing"

If you've been thinking of choosing a bi-wire cable to squeeze the ultimate fidelity from your high-end hi-fi components or premium home theater system, try the bi-wire version of Analysis Plus Silver Oval Speaker Cable. The metallurgy and construction are identical to the standard Big Silver Oval Speaker Cable, but in a bi-wired configuration and termination for the highest possible level of performance.

"Opening UP of the Top End"

"The most obvious difference with these speaker cables is the opening up of the top end," marvels Doug Blackburn in the December 2001 issue of SoundStage!. "Some cables seemingly roll off the upper frequencies with my Blue Circle BC2 mono amps in use. The Silver Ovals don’t. In fact, they allow my BC2 amps to open up and really sing. Highs are pristine and extended, and the bottom end is also very strong."

Stereo Times has a similar high opinion Silver Oval. "The differences wrought in my system by the addition of the Analysis Plus Silver Oval cables and interconnects are positive, dramatic and immediately apparent - quite an achievement when you stop to consider that I already use a reference-caliber product," says Clement Perry in the May 2000 issue.

Revolutionary Hollow Oval Design

Analysis Plus is uniquely qualified as an authority on speaker cable design. The Detroit-based company earned its reputation testing and analyzing cables for leading cable manufacturers whose names you'd recognize in a flash. After examining the best, Analysis Plus decided it could do even better by developing its own proprietary hollow-oval conductor design.

Why the unique conductor geometry? Mark Markel and Qinwei Sun, the chief engineers at Analysis Plus, determined that round cable used in conventional speaker cable designs has high levels of current bunching, skin effect phenomenon, and other frequency characteristics that degrade signal quality. Rectangular conductors were a little better, but these suffered high electric field values caused by sharp corners which can also cut into and injure the dielectric when the cable is flexed.

After many computer simulations, Analysis Plus found that a hollow oval cable was the best design due to its minimal change in resistance with frequency, plus other benefits. The company chose a flexible, braided conductor rather than the conventional solid conductor, which is susceptible to kinks and deformations with resulting signal degradation. A unique woven pattern places every wire statistically as close to the return current as every other wire for evenly distributed high-current density and superior sound.

Meticulously constructed using a patent-pending woven design, Silver Oval Speaker Cable is made by layering pure silver over a stabilizer strand of high-purity OFC oxygen free copper, which is then woven into a 12-gauge hollow oval conductor. The Silver Oval Cable is then combined with a computer matched dielectric and is shielded against EMI and other interference for ultra-quiet, noise-free performance. Instruments emerge out of a silent background. Depth and detail are exquisite.

"Resolution is Top Notch"

"Highs are pristine and extended, and the bottom end is also very strong," observes SoundStage!. "Resolution is top-notch."

Due to its unique geometry, each Silver Oval speaker cable requires handcrafted termination requiring an hour of work on each cable for a standard cable, and longer for this bi-wire version. The Silver Oval speaker cable is factory terminated with Analysis Plus' exclusive silver-plated T-1 spade lugs milled from a single block of copper. See inset box at right for details.

"Internal Bi-wire", aka IBW, means the cable has one set of connections (+/-) on the amp end, but two sets of connections on the speaker end. This configuration is recommended for loudspeakers set up for bi-wiring. If your speakers are not set up for bi-wiring you should not purchase cables terminated this way.

2019 Editors' Choice Award – The Absolute Sound

"The Big Silver Oval speaker cable brims with resolution and dynamic life."

"...this is a cable you don’t listen to, but rather listen through. Recorded music simply flows in an earthy and tonally authentic manner. Harmonics align; images and soundstage conform with no serious sonic missteps. And its real-world affordable."
