Electro Acousti Cryo-Litz 7N UP-OCC | 7N SCC cables

Build Quality.

  • 7N Neotech UP-OCC Copper Cryo Litz

2

This is one of their most popular cables. The one I have is made up of 4 cores of Neotech’s 7N UP-OCC Litz 1 structure wire (wire’s link in EAC Store).  The quality of wire is very good, it being flexible and supple. The braid is tighter pre-Y-split and a bit looser post. I chose to have ear guides and they are ergonomically shaped and comfortable. Microphonics are very minor and do not interfere when music is playing.

I chose Eagle’s large Rhodium-plated jack in 3.5mm. This jack itself costs $14 alone and is one of my favorites out of all the cables I have as it oozes high quality. It is very solidly built and feels great to hold and use. Rhodium plating also lasts longer than gold plating. As for connectors, I chose classic silver style 2-pin versions. They cost around $8 for a pair and like the jack are high quality and inspire confidence when plugging them into tight sockets. I chose the small black carbon fiber Y-split for this cable and that too is of very good quality and looks pretty cool too. The chin slider sadly is a bit loose and doesn’t work as efficiently but fits in the design language well.

It is cryogenically treated and strengthened but American Cryo-parts. I do not know if that makes a difference or not, but well at this price, what’s the harm!

This one is a bit more expensive than the previous UP-OCC cable at $135 . It feels slightly thicker and has a PE sheath which makes it a bit more solid than the UP-OCC cable, in a good premium way. The PE sheath also makes the braid feel better and tighter post the Y-split. It is also more flexible and easier to wrap than the previous cable. This too has the same comfortable ear guides and very minor microphonics. Overall, I like this one’s feel better than the UP-OCC.

Like the UP-OCC cable, I again chose Eagle’s large Rhodium-plated jack in 3.5mm and classic silver style 2-pin connectors with this one too. For the Y-split I went with the Red Sandalwood type instead for a change. It is bigger and fatter than the one on the previous cable and I much prefer this one. The chin slider works better on this cable than the previous one.

This one too is cryogenically treated and strengthened by American Cryo-parts. I do not know if that makes a difference or not, but well at this price, what’s the harm!

Technical Measurements.

  • 7N Neotech UP-OCC Copper Cryo Litz
  1. Impedance – 240 mΩ average
  2. Capacitance – Around 72pf average
  3. 26 AWG
  4. Type 1 Litz

Though the impedance measured slightly higher than I was expecting (I expected around 180mΩ), it actually conducts cleaner in practical usage, providing a slight volume boost over most stock cables.

  • 7N Single Crystal Copper Cryo Litz STE
  1. Impedance – 150 mΩ average
  2. Capacitance – Around 68pf average
  3. 26 AWG
  4. Type 1 Litz

I’m writing average values on the safeside as my main hi-res multimeter is down and the standby one is not as sophisticated as the main one. So, I borrowed another hi-res multimeter from my engineer friend to cross check quickly.

  1. Quick point of clarity some might find helpful: when building your cable from components on the Electro Acousti store, there are sliders designed specifically for 4 core cables. The option isn’t obvious, and it isn’t available for every splitter, but the 4 core sliders do work very well on the 4 core wires, and likewise for the 8 core sliders on 8 core cables.

    For Zen Sen’s pre-made cables, he’s happy to accommodate requests, and I’ve ordered a few with the 4 core slider specifically because of the issue you mention.

    In case it isn’t obvious, I’m a HUGE fan of EA’s cables, and Zen Sen himself. He’s truly a joy to work with, and it’s great to see him recognized outside a head-fi thread or two!
