Really affordable High-End Loudspeaker Cable featuring Tube Conductors of 4 x 2.0 mm2.
By spinning a multi-strand layer on an insulating core, Supra has increased the conductor cross-section - resulting in inductance of a vanishingly low 0.28 mH/meter. (Inductance robs your system of high frequencies.)
With high-grade polypropylene insulation and individually shielded conductors, Quadrax rejects noise as well as the most expensive speaker cables on the planet - at a fraction of their stratospheric prices. This is state-of-the-art performance - that the average guy can afford!
The tube conductor design means that 120 individually tin plated strands in a braid forms a tube around a PP plastic core. It forces the music signal to meet the same crossection area irrespective of frequency.
Terminated with Supra Combicon, Solid Copper, 24K Gold Plated Crimped Body connector and either Spades or Banana pins to suit your requirements.
The CombiCon Connector (as used on the flagship Supra Sword cables)
24K Gold Plated Copper connector crimp body with a M6 thread, a contact part which can be either a BFA/Banana or a Fork and finally a sleeve to finish up the perfect joint.
The crimp body is as said, crimped on to the cable strands forming an air tight connection, a very delicate junction between cable and contact.
Quadrax comes with crimped M6 threaded adaptors and a set of connectors with corresponding threads. The picture shows the 24K Gold plated spade and banana/BFA connectors, The set includes all connectors for the absolute majority of todays connection options and most likely also your future preferences.
The transition between the cable and connectors is critical. In order to maintain the superior cable and contact properties, we crimp the unit together at high pressure, making a perfect, air tight, joint. Contact mounting is performed by trained professional using Supra contacts and tools.
If configured in a Star Quad conductor formation (single wire/full range) RFI pickup and outgoing magnetic fields (lowered inductance) are almost completely cancelled out, thanks to the symmetry of current in the opposite conductor pairs.
Finally the strand tin plating will counteract any current jumps tendencies between the strands.

Customer Reviews
I recently had to move my components away from between the speakers which meant I needed a 9m set of speaker cables. I had read good things about Supra cables so decided to give them a go.
I rang Mark ( yes, that's right, I was actually able to speak to the person who was going to make my cables! ) and we had a brief discussion about the Rondo cables and I emailed him later for a quote. After seeing my system, Mark suggested that the Quadrax cables would probably be more appropriate and offered me a very good price so I took the plunge.
As part of the service Mark burned in my cables which took 4 days. They duly arrived about a week after I ordered them and I have to say that first impressions were very favourable. Each set came in its own bag and were beautifully made. These are substantial cables! I plugged them in between my Williamson KT66 amps and the Tannoy 15" Monitor Golds and away I went.
I haven't had them long but initial listening suggests an improvement in imaging and detail which is saying something because the Tannoys were no slouches in that department before! Needless to say I am very happy with my purchase.
All through the process, Mark and his wife Charmayne have communicated very well and have been a pleasure to deal with. I couldn't recommend them more highly.
