Jorma Design's No. 2 Biamp (Pair)
Speaker Cables by Jorma Design
Manufacturer's Description:The no.2 series of cables are built with the same material and connectors as the no.1 cables, except for the tube with the Bybee Quantum Purifiers that are not used in the no.2 series.
These cables are fully upgradeable to the no.1 cables.
Jorma Design loudspeaker cables and interconnects are composed of copper of the best possible quality. We decided to use this material after experimentation with many other materials, as well as with other copper configurations. Copper delivers the most neutral, transparent, and natural musical signal. Jorma Design No. 1 and No. 2 cables employ 99.999999% pure copper. No. 3 cables employ 99.9999% pure copper. These numbers do not refer only to oxygen, but to ALL polluting materials and metals. All conductors are subjected to a spark test using 6000V impulse tension before we use them to produce our cables.
The dielectric of all Jorma Design cables is made of the purest, non-colored Teflon. The connectors we use are very carefully selected for the best sound quality. Where solder is used, it is also carefully selected for the same reason. The connectors for the No. 1 and No. 2 speaker cables are assembled with gold-plated copper crimps, with no solder employed. In all No. 1 cables, we use Bybee Quantum Purifiers, which minimize distortion without adding any negative sonic effects.
In addition to the use of the finest materials in all aspects of their design, the unique structure of Jorma Design cables contributes to their natural sound. The filling in the conductors is a special ceramic glass fiber, with ultra-thin threads. Inside the conductors are hundreds of these fibers, and around the fibers are thin copper threads wound exactly in parallel. The conductor therefore forms a tube that has a thickness of 0.1mm. We found that this form gave the best-sounding results, but by itself, such a thin copper tube is not sufficiently stable for normal use. The solution was to employ the ceramic-fiber filler to get as close as possible to the tube form. While it is very difficult to produce conductors in this way, the finished product is very hard to damage. In fact, Jorma Design cables are so strong that they can be used to lift a car!
Jorma Design cables employ sophisticated shielding to reject radio frequency interference (RFI) and electromagnetic interference (EMI), and to stabilize the cables against vibration and microphonics. The shielding for all Jorma Design cables (except No. 3 speaker cables) is heavily braided, tin-plated copper that works very effectively in combination with the special geometry of the conductors to ensure that up to 98% of the incoming and outgoing RFI and EMI are removed without any compromise to the audio signal.
One question that is frequently asked about Jorma Design cables is: Why are they so thin? For that price, shouldn’t they be thick and heavy? The problem with taking diameter as an indicator of quality is that making Jorma Design cables thicker would adversely affect the sound. We have found that using the smallest amount of the insulation that surrounds the conductors results in the best sound. If we were to use more than is absolutely necessary to make the finished product strong, safe, and long-lasting, it would degrade the sound. That is why our cables look as they do.
