アコースティックリバイブ RCA电缆（1.0m・ペア） RCA1.0PA Acoustic Revive 1.0PA RCA 信号线用的是PCOCC-A椭圆型单一导体。PCOCC很多中低端产品都已经在用着，加上褪火煅烧的-A处理也不稀奇，正在用的oyaide605耳机线就是。似乎特别之处就是单一导体设计，然后是无焊点接头、真丝包裹的线体。这些处理蛮fancy的，但还是没有纯银线材料感觉高贵似的？另附英文评测如下：
The conductors are oval Pure Copper by Ohno Continuous Casting (PCOCC-A) wire. The PCOCC-A is an ultra-high purity (greater than 8-Nines, or 99.999999%) single-crystal copper wire that has been annealed—the 'A' in PCOCC-A—to increase its pliability and conductivity. 6-Nines or less is what you see in almost all other cables, and Acoustic Revive tells me the measurable and audible difference between the performance of 6-Nines conductors and their 8-Nines conductors is profound, and well worth the extra effort and expense involved in producing them. Acoustic Revive also makes a point of saying that the oval shape of their PCOCC-A conductors means they do not have a resonance point, which contributes to a smoother, more transparent, three-dimensional, and articulate sound compared to other kinds of conductors.
The PCOCC-A conductors are covered with a natural silk dielectric, which Acoustic Revive says gives a more natural and spacious feel to the music. The silk covered PCOCC-A conductors are then covered with Teflon coated flexible copper tubing that provides 100% shielding from RFI. Acoustic Revive then covers the entire cable assembly with mesh polyurethane tubing containing embedded carbon particles that provides additional shielding and vibration isolation.
Acoustic Revive interconnects and speaker cables are terminated with solderless connectors that are works of art all by themselves, looking more like they are produced by a maker of fine jewelry, say Tiffany, than an audio company, and whose materials qualities are the equal of the PCOCC-A conductors. Acoustic Revive doesn't believe in using soldered connections because a solder joint between the conductor and connecter "solder reduces conductivity and sound quality".
Acoustic Revive's flagship Single Core series of cables are constructed entirely by hand, and given the ultra-quality of the materials, and the fanatical attention paid to quality of construction, it should come as no surprise that they are expensive. If you're trying to save money in these difficult economic times, I'd say you might want to look elsewhere. However, if you're not troubled by their cost, and are looking for exceptional sonic and musical performance in an ultra-quality product, then please keep reading.

Wrapping Up
I started out this article by saying a quote from Confucius (551 – 479 BCE) was reminded me of the Acoustic Revive Single Core cables: "Much can be realized with music if one begins playing in unison, and then goes on to improvise with purity of tone and distinctness and flow, thereby bringing all to completion." The Single Core cables really brought everything together in my system, and "much was realized" through their use, with their relaxed clarity giving a purity of tone and sheer musicality that is unparalleled for my system, which frankly was sounding pretty darn good already. The difference was not subtle, it was transformative—it was HUGE.
The Acoustic Revive Single Core are the finest set of cables I've ever had the pleasure of listening to in my system, and you should interpret this as a rave review lauding their virtues. The Single Cores are very good at portraying the sonics captured during the recording process, but more importantly they are simply outstanding at portraying the musical content of a recording and turning it into an astonishingly pleasing musical experience—they receive my highest recommendation.
As I mentioned above, I'm now convinced that controlling vibration in the speaker-to-speaker cable interface is for real and worthwhile, but I'm ambivalent about recommending the RCI-3s because I'm don't feel like they are a fully realized product yet. What I'd really like to see is Ken San come up with a solution that inserts between the speaker binding posts and the speaker cable, as I think it would yield an even larger (and more reproducible) improvement. But don't let me stop you from trying to reproduce the little experiment that I did if you want to do it—it does work.
This Chapter of the Acoustic Revive Chronicles brings to a conclusion all of the items I have in-house from Acoustic Revive to write about, and it has been a fun and eye opening journey. I have been impressed by the enormous improvement in my system's performance that the Acoustic Revive products have provided, both individually, and as an additive whole.
The Acoustic Revive products really improve the musical attributes of recordings like timbre, meter, tonality, harmony, beat, tempo, syncopation, and melody—all of which became more convincingly natural and life-like. The overall effect has been make music through my Hi-Fi rig more dramatic, bigger, more exciting, and more entertaining—more like you experience in life—more naturally life-like.
I found that the sonic attributes as well: things like soundstaging, imaging, transparency, perspective, and the sense of recorded space all became more tangible and vivid. The Acoustic Revive products provide a very nice balance of providing a big dose of improving the musical attributes, with an appropriately sized addition of sonic improvements that enhances the music, with the net effect being that I'm drawn deeper into the musical experience during listening sessions. So all-in-all, the Acoustic Revive products have been winners in my home audio system, and they have gotten me magically close to Ken-San's (and my own) goal of a home audio system that "sounds natural and not as though it is being played back over an electrical device."
I would like to offer my sincerest thanks to Mr. Ken Ishiguro, the owner and visionary designer of Acoustic Revive, and Mr. Yoshi Hontani, the exporter of Acoustic Revive products, for giving me and the readers of Positive Feedback Online an opportunity to experience such a vast array of products—it was a real eye opener, and a tremendous amount of fun.
Pricing: The Acoustic Revive Single Core speaker cables are $1800 US for a terminated 2-meter pair, the Single Core RCA interconnects are $1275 US for a 1-meter pair, and the RCI-3 cable insulators are $175 US each.
Quality of construction: Like all Acoustic Revive products, the Single Core cables and RCI-3 cable insulators are all built to astonishingly high standards.
Condition of products received: Perfect.
Human interactions: Mr. Yoshi Hontani (Acoustic Revive exporter) is the best person to work with I can imagine. He is expedient, courteous and helpful. The same goes for Mr. Ken Ishiguro of Acoustic Revive fame, and US importer Mr. Joe Cohen of the Lotus Group. A class act all the way around!
