Use this solid core insulated cryogenically treated silver wire in your CD player, your pre-amplifier, your amplifier, in your speakers and more! The 0.5 mm solid core silver wire is suitable for almost all wiring purposes, from the CD to the speaker: internal wiring, interconnects, speaker wires, everything. This wire is custom made to Audio Consulting's specifications. The wire is now offered with cryo treatment. Several cryo cycles  provide a substantial improvement to the already outstanding wire. They are carefully performed at a Swiss University and thus allow for very tight  quality control.

The diameter does not exceed 0.5 mm to avoid skin effect and its implications. The polyesterimide insulation has to be as thin as possible to help stop dielectric absorption and electrostatic micro-discharges. There has been no bad cumulative effect heard as reported with some other silver wires. This cumulative effect could likely be due to multi-stranded nature and / or the Teflon insulation.

Typical Applications:

Speaker wires
Especially suitable for high-efficiency speakers. For systems above 96 dB/W/m, a non-twisted pair of up to 3 meters will offer the best performance. For lower speaker efficiency you may use two, three or more runs per polarity. For example, 92 dB speakers would use 4 runs. The runs of cryo'ed silver wire must be tightly twisted for each polarity, however not twisted between the poles. Cotton sleeving will enhance the performance even more plus offer extra protection. Speaker cables may be built with one layer of 2 mm cotton sleeving per pole (4 mm if necessary), important that you should not twist the two polarities but let them run freely.

Interconnects
To make a very high performance interconnect, simply twist a pair of the 0.5 mm cryo silver wire. Interconnect would be best covered using 2 mm cotton sleeves around each of the two poles and then twisting the two poles. After that you can put one or even two layers of the 9 mm cotton sleeves around the whole set-up. Best results may be obtained without any shielding, however you may add some shielding if you are in a non-differential mode.

It even works with digital interconnects, although it is preferable to use the 0.15 mm silver wire in this application.

Rewiring

Amplifiers, pre-amps, valve equipment, CD Player, DACs etc, can all be rewired to some extent. Single runs of 0.5 mm are great for rewiring purposes of analogue signals. Cotton sleeving will be an advantage. The ground also should be of the same topology.

Grounding
The star grounding system: take as many wires as you have ground connections. With a butane flame, melt all of them together at one end. All connections go with one wire to this single point, which becomes the perfect star grounding.

Important
As with all types of wire, you must be careful not to exceed the allowable current for this diameter of wire. Multiple runs may be used to increase the current carrying capacity if required. The silver wire has been used up to about 30-40 VDC without any further insulation. The enamel should be good for a few hundred volts, but this has not been tested. We do not recommend that this wire be used for high voltages applications without appropriate insulation and precautions in place.

Since the cryo'ed silver wire is insulated with a polyesterimide coating, this will have to be removed before any soldering can take place. It can easily be done by scraping with a sharp knife, taking care not to make any kinks in the wire or by burning off with a flame.

Additional cotton sleeving not only increases isolation, but can can also improve the sound, even for internal wiring of electronics and even in the power supply.
