"I just wanted to thank you for the [Whirly Wisp] cables. I burned them in over the last month and holy $%^&! My last experience with upgraded cables were some Monster speaker cables I got as a gift nearly 20 years ago. I finally got the time and money to upgrade my old system and wanted to try out some nicer interconnects for the new components and system. YACCo cables [Whirly Wisps] were the perfect introduction to the higher end market. I have to say that I was skeptical, but have now heard a clear difference... I will be trying your speaker cables during my next upgrade. Thanks again," - Ron S.

These 'Shootout' comments discuss the final round between the two best performing cables, the Cauda Equinas and another brand. The entire shootup consisted of cables costing up to slightly more than $2000. The brand-name was omitted at the customer's request. Note, the below shootout was done with a shotgun biwire pair of Cauda Equinas.
"I just finished the shoot-out between your cables and the [other brand]. The two cables are exactly alike in terms of clarity, microdynamics, macrodynamics, soundstage width, soundstage height and midrange performance. The [other brand] had a minor edge in soundstage depth and bass extension. The Equinas clearly outclasses them in all aspects of treble performance. The upper region was as smooth as glass; not as in rolled off, but as in "liquid"! The treble had all the extension I could ask for but without a hint of grain. It was like comparing very good digital to analog (no contest really). All of this with a black background while still maintaining air around the instruments in a totally cohesive soundstage. The Equinas allowed me to relax into the music more. The sonic picture they painted was more real.
Needless to say, your cables are the winner!!!! They earned a permanent place in my system. Congratulations on an excellent product! I must admit though, midway through the break-in, I didn't think they had a chance. The background was still "whitish", and the bass extension and impact couldn't hold a candle to the other cables. When you told me the background would improve, but the dynamics wouldn't, I thought it was a done deal. Fortunately, you were only half right. The background did improve, but more impressively, so did the bass! It was a serious improvement that put them not just back in the race, but in front of the race!
Isaac, thanks for a wonderful set of cables. You should be extremely proud of your accomplishment. I am proud to own them.
Thanks again for everything. It was a pleasure doing business and corresponding with you.
...By the way, your cables are the most visually appealing of all the cables. They look like jewelry. Good job!
Sincerely, KG"

"I've been using these little wonders in my system (Denon/Music Angel/Cambridge Audio/Dahlquist) for a few months now. They replaced comparable silver IC's. The Wisps just sound right. I don't feel like I'm missing anything nor hearing anything I shouldn't. What more can you ask of an interconnect? Thanks for a great product." Lee P.

"My Whirly Wisps replaced another set of silver IC's. I made those myself using silver IC wire from a DIY supplier. I used the same connectors as the Whirly Wisps. The Whirly Wisps outshine the IC's I made myself and the cost was the same! I'm running through a pc, an outboard DAC, a tubed single-ended amp and highly regarded horn speakers. The Wisps have deeper bass, a smoother and more open sound and their timbre is more natural than the silver IC's they replaced. They are lively and musical- a good sense of pace, rhythm and timing. Such a deal!" - Lance P.

"Cables are wonderful!! Totally opened my system up. I couldn't believe how much more dynamic it was. Much cleaner sound. Plan on purchasing a couple more pair in next couple weeks so get ready !!! I didn't realize how much I wasn't hearing even with good ICS." - Gary P.

"Your silver cables would be worth [a 14-16 hour] drive [to hear]! They are working great with the WA6 and my HEV70. Good job, very balanced sound that I didn't expect from silver! Maybe there is something to the "teflon air-tube dielectric" concept…Your RCA interconnects between source and WA6 were fantastic, and [we] were very impressed." - Larry G.

"These replaced a pair of Belden 89259 cables terminated with Eichmann Bullets... I certainly like what you've got here and... they'll be staying where they are." - Eric A.
