Internal Wiring Kit

• for high-end-quality internal wiring of speakers and amplifiers
• cross section per conductor (6 single solidcore wires): 1.2 mm²
• structure similar to the speaker cable "exact"
• ready-for-connection

For high-end-quality internal wiring of components. The ON.HIGH solidcore wires are the basis. These wires are glued together like a baked varnish coil. Therefor the cable will be soaked with the c37-varnish during building. This is the most effective method I know of to control the magnetic forces in the cable. The topology is similar to the speaker cable "exact" but without the glassfibre rods which are not necessary for permanent installation in an enclosure.

Silver Wire

• diameter: 0.5 mm
• cross section: 0.2 mm²
• purity at least 99.99% (4N)
• long-crystalline
• polished surface
• cryo-treated

Silver Foil

• thickness: 0.07 mm
• width: 30 mm
• cross section: 2.1 mm²
• resistance: 7.6 mΩ/m (at 20°C)
• purity at least 99.99 mass percent (4N)
• coarsely crystalline
• rolled surface, highly glossy
• cryo-treated

There is always room for improvement! Together with my metal supplier we improved surface quality of the silver and copper foil significantly. This is now highly glossy! And we raised thickness from 0.05 to 0.07 mm. The best foil I ever had.

Copper Foil (OFCu)

• thickness: 0.07 mm
• width: 30 mm
• cross section: 2.1 mm²
• resistance: 8.0 mΩ/m (at 20°C)
• purity at least 99.99 mass percent (4N)
• coarsely crystalline
• rolled surface, highly glossy
• cryo-treated

Enamelled Copper Wire ON.HIGH

• cross section: 0.2 mm²
• diameter: 0.5 mm
• purity at least 99.99% (4N)
• enamelled copper wire
• cryo-treated

Excellent high purity enamelled copper wire. With outstanding sound properties. I use this wire for my internal wiring kit and for the speaker cable "exact". The BW0 and BW1 cotton tubes are a perfect match for this wire.

Enamelled Copper Wire /
Magnet Wire

• cross section:
  MD1: 2.0 mm² MD2: 3.65 mm²
• resistance:
  MD1: 8.4 mΩ/Meter MD2: 4.6 mΩ
• enamelled grade 2, dielectric strengh min. 2kV
• thermal class 200

These wires are best suited for making low resistance power connections, earth bars and star wiring. MD1 is a round wire with a diameter of 1.6 and MD2 is a flat copper wire with a width of 3.0 and a height of 1.25. The following glass fibre sleeves fit these wires perfectly and make them very resistant to mechanical stress.

Glass Fibre Sleeve
PUR Coated

• inner diameter:
  GS1: 1.5 mm GS2: 2.0 mm
• wall thickness each 0.5 mm
• fibreglass mesh with
  polyurethane coating
• dielectric strength: 4kV
• thermal class "F" (-30 bis +155°C)

Extremely robust wire insulation. Fits perfectly for the magnet wire offered above.

Unbleached Cotton Jacketing

• for insulating and protecting audio cables and electronic parts
• prevents undesired electrostatic charging
• effectively absorbs impact sound
• sizes are rough values; the jackets may be stretched or compressed considerably

LT4320 Ideal Diode
Bridge Rectifier

• LT4320 from Linear Technology
• minimal losses
• almost no transformer ringing
  -> snubber becomes superfluous
• various connection options

Standard rectifiers lose 2x0.7V forward voltage. Due to this loss, cooling is required above a certain current level. The LT4320 provides a remedy. This IC controls four MOSFETs like diodes. Minimal voltage drops across the MOSFETs. This means that a few 10 amperes are possible without major cooling measures. The circuit board is designed for dual mosfets. Footprint: PowerPAK 8 x 8L. More information on my Tuning-Seite. (German only) ATTENTION: two modules (double pack) are required for a symmetrical power supply (+/-).

Adapter-Print
SOIC14 to DIL14

A QUAD-OpAmp (which I like) is no longer available in a DIL14 package, but only in SOIC14. There are no adapters on the market. I realised why when I was doing the layout: the land pattern of the SOIC chip doesn't match the hole pattern of the DIL14 package. Pin 1, 3, 10 and 12 are slightly out of line. But if you use small wires instead of pin rows, you can ‘bend’ it to fit.

WBT RCA Connectors

• WBT-PlasmaProtect
• contacts NOT magnetic
• exceptional sound qualities
• patented WBT clamping mechanism
• cryo-treated

The "nextgen" from WBT shines with the minimum-material-principle and a patented clamping mechanism for the ground signal. Now with the new PlasmaProtect method for the gold plating.

KLEI Innovations

• KLEI Harmony (Bullet) Plug
• contacts NOT magnetic
• exceptional sound qualities
• cryo-treated

The "Next Generation" from Keith Eichmann has some improvements to offer. IMHO the best about this truly high-end plug is it's price!

Hollow Banana Plug

• base material: beryllium copper
• contacts NOT magnetic!
• direct gold plating (NO nickel)
• direct silver plating (NO nickel)
• cryo-treated

The standard plug for speaker cables. Minimum use of material. Very stable and durable. Now also available as a silver-plated version. GUARANTEED nickel-free and non-magnetic.

Spade Connector from
PCB material

• 70µm both sides
• suits 6 and 8 mm binding posts
• width front: 14mm; width back: 10 mm; length: 30 mm; thickness: 1.6 mm
• silver plating
• cryo-treated

The base for the Supreme foil speaker cable. Both foil and wire can be soldered onto the copper surface. The shoe has 3 vias, both copper surfaces are connected to each other!

Silver Jack for Hollow Bananas

• purity at least 99.99 mass percent (4N)
• material thickness 0.5 mm
• high polish finish
• cryo-treated
• reduces eddy current by design

Simple but effective contact element. Only a 5 mm bore dia necessary to mount in e.g. wood or any other non-conductive material. Provides best contact for hollow bananas.

Connection Terminal for
Bananas and Spades

• shown is the standard model
• size, shape and number of connections freely selectable
• contact element made of 4N silver
• terminal and bridge is made of acrylic

The connection terminal to the silver jack. The standard model has a width of 80mm and a height of 60mm. The distance between the jacks is 40mm. The bridge clamps spades via the central locking device. If bananas are to be plugged in, the bridge is parked vertically or removed.

Shown is the "standard model". As I manufacture these terminals myself, you are completely free to request any other shapes and, above all, more connection sockets.

Furutech Pure Transmission

• here you find everything from Furutech
• and here are the prices
• all prices are negotiable

I buy without exception from the German Furutech importer PADis.

Bals 7372 Safety Plug

TentLabs XO 4.2336MHz

• extremely low-jitter clock
• for the first Philips CD player generation
• including ferrite bead and DIP-socket

The master clock of first-generation Philips CD players features a frequency of 4.2336 MHz. Guido Tent was so kind to provide this frequency to me. The clock is 100 times more accurate compared to the original quartz.

C37-Varnish

• optimized for room temperature
• with suitable thinner
• with syringe and needle for comfortable measure out and mixing
• here you find instructions how to use (german only)

Dieter Ennemoser for me is a constant instance regarding violin varnisch.

Cryo-Treatment

• alters grain structure positively
• increases contact-durability
• reduces stress in material

Cryo-tuning specifically for audio is offered by CoolTech in Austria, among others. As far as I know, cryo-treatment was developed for motor sports before audio-enthusiasts discovered it. It is kind of aging the material that leads into a relaxed structure in the material. Already the old Japanese buried their Samurai swords into the snow over the winter to be successful in the battle ...
