silk wrapped 4N solid silver tonearm rewiring kit


We have now added a solid silver tonearm wiring kit to our store. This features our  0.2mm 99.99% pure solid silver wire, which is double wrapped in pure silk. Also included in the kit are our gold plated cartridge tags, high silver content solder, and coloured heat-shrink tubing to give your rewiring job a professional finish.

This is an excellent upgrade for your tonearm. The solid core silver wire provides exceptional conductivity, resulting in a low impedance, and capacitance, allowing for better control of critical cartridge loading.

El Cid MKII cable sale

We thought we would start the summer of 2017 with a cable sale. We are upgrading our El Cid MKII cables, replacing the Amphemol RCA phono plugs with our new RC85S plugs. The new version of the cables will be slightly more expensive due to the increased cost of the new phono plugs.

We have a stock of the old version of the El Cid cables which we are now offering at a 10% discount while supplies last. The sale does not apply to the El Cid MKII ‘Acoustic’ cables as we have no stock remaining with the old phono plugs.

To get the discount simply enter the following coupon code at checkout, ELCIDSALE17.

Cable update

Some of you may have noticed that we had a limited number of El Coto interconnects available. This was due to a delay receiving the new batch of the phono plugs used to make this cable.

The plugs arrived last week, and we spent the weekend building a new supply of El Coto silver interconnects. These are now available to order from our online store.

4N solid silver headshell leads

As our stock of silver litz headshell leads is running low, we have been trying to find a new supplier of affordable silver leads. This has proven to be more difficult than expected. The few headshell leads we have found are very expensive, and much of this cost is down to expensive packaging and advertising. With the recent arrival of our double silk covered 4N solid silver wire we thought we would have a go at making our own leads. The construction process turned out to be more involved than originally expected, but after a few trial runs with the soldering iron we managed to produce a set of prototype headshell leads.

We mounted these leads on a Grado Reference Platinum in a Nagaoka Ebony headshell. The headshell was mounted on a Fidelity Research FR-54 tonearm on our PTP reference Lenco turntable. The results were unexpected to say the least. The sound was much more focused, and had an added clarity that was lacking from this cartridge/headshell combination with the previous setup. We were surprised  by the difference in the sonic signature that such a seemingly small change could make.

We have tried solid silver headshell leads before, and had been impressed by the sound. However, this was better, and it is hard to explain what could be behind this improvement. The one difference between these leads, and the previous silver leads, was the double silk wrapping. We are big fans of natural materials used to cover cables, and silk in particular offers excellent damping. Whether this is enough to explain the difference we hear between the bare silver, and the silk wrapped, we really can not say. When compared to litz leads the difference is even greater. One important characteristic of single core wire is that its capacitance is much lower than litz type wire. Although not a major concern when using moving coil cartridges, moving magnet and moving iron cartridges are sensitive to capacitance. The Grado cartridge used in our tests is a moving magnet design, and this perhaps goes some way to explaining the difference we hear using our new 4N silver leads when compared with the original copper litz leads.

Based on the success we have had with these leads we have decided to add these as a stock item in our shop. We are just waiting for some materials to arrive before we can go in to full production. These should be arriving any day now, so the headshell leads should be available within a week.

Playing with impedance

When we first began playing with step-up-transformers (SUT) here at lencomotion audio, we wanted an easy way to vary the secondary loading. We had a variety of transformers, all of which sounded different with each cartridge, and to get an accurate idea of what each SUT was capable of, we had to be able to change the impedance for each cartridge. It needed to be something that allowed us to make changes without having to run to the solder station in the workshop. A quick rummage through our parts box led to the construction of the following pair of cables.

These were easy to make using standard male and female RCA phono plugs, a short length of high-quality cable, and a pair of standard DIL sockets mounted on project board and protected with heat shrink tubing. The DIL sockets are mounted in parallel with the signal cable, and allow resistors to be easily added to the circuit by plugging them in to the DIL socket.

The cables are now a permanent fixture in the listening room, allowing us to easily adjust impedance when playing with cartridges and step-up-transformers. Anyone currently using a SUT with a fixed impedance should have a go making a set of similar cables, and have a go varying the impedance of the system. If you find that adding a resistor improves the sound, then a similar value resistor can easily be more permanently soldered to the phono outputs. For those folks who are not interested in DIY-ing their own cables, contact us, and we would be happy to make up a set for you.
