Atlas Arran Ultra L RCA Grun Interconnect Cable

The Arran Ultra L RCA Grun elevates the Atlas previous top of the range OCC copper interconnect (Mavros) to another level, created as a true ‘no compromise’ design to complement the performance of ‘high-end’ audio systems. Arran employs a unique 3D printed liner within the Ultra L plug, reducing mass and the influence of the connector itself to extremely low levels.

The Arran Ultra L RCA Grun uses the highest quality ‘6N’ (99.99997% purity) elongated crystal copper manufactured using the OCC (Ohno Continuous Casting) process, ensuring the signal follows a faster, cleaner and more direct path.

The cable utilises a pair of conductors, each made up of six solid OCC strands surrounding a seventh central wire, tension wrapped in a microporous PTFE dielectric. An advanced continuous screen with a copper shielding braid ensures minimal RF interference and noise susceptibility.

In Atlas ‘dd’ (dual-drain) configuration, twin symmetrical drain wires connect the screen to the cable return/plug interface, allowing cable termination without distorting, twisting or mechanically stressing the precision-laid screen. Typically, screened cables suffer from screen distortion when prepared for production. Cutting and twisting the screening braid has a measurable impact, effectively changing the impedance and, therefore, the cable’s performance. Using tools we created for this specific task, Atlas precisely calibrated build process maintains the required conductor geometry and ensures the highest level of manufacturing consistency and reliability.

Termination is with the Atlas latest generation innovative ultra-low-mass ‘Ultra L’ (Latik) RCA which uses a 3D printed liner component and cold-weld connection. In a cold-weld (solder-free) connection, the metal of the connector plug and the wire are squeezed together under a calibrated pressure to form a robust, consistent, air-tight metal to metal contact with no deformation of the cable dielectric. The result is a smooth, uninterrupted signal path which behaves as one continuous entity.

Incorporates Atlas’ Grun Coherent Earthing System connector (basic adapter included).

Standard or Luxe finish options are available.

    Ehh. Not for me.
    Color: Gray
    Foot slides when walking in them. The fit was tighter than lead to believe. It did hold the moisture in but the silicone patch is small

    Transformative for Dry, Cracked Heels!
    Color: Original Grey
    I recently purchased Dr. Frederick's Original Moisturizing Heel Socks, and they have truly transformed the condition of my feet! I can’t recommend them highly enough. Effective Moisturization: These socks are infused with moisturizing agents that work wonders. After just a few uses, I noticed a significant reduction in dryness and cracking on my heels. My feet feel softer and smoother, and I love that I can wake up to beautifully moisturized skin. Comfortable Fit: The socks are incredibly comfortable to wear, with a snug yet gentle fit. I appreciate that they don’t feel restrictive, allowing me to walk around my home while wearing them without any discomfort. They are also lightweight, making them easy to slip on before bed. User-Friendly: They are super easy to use—just wear them overnight, and let the socks do their magic. I love the simplicity of incorporating them into my nighttime routine. Durable Quality: The quality of the socks is impressive. They wash well and have maintained their shape and effectiveness after multiple uses. I feel confident that they will last a long time. Final Thoughts: If you're struggling with dry, cracked heels, I highly recommend Dr. Frederick's Original Moisturizing Heel Socks. They are a fantastic investment in foot care and have made a noticeable difference in the health of my skin. These socks have become a must-have in my self-care routine!

    These worked for me!
    Color: Original Grey
    They worked great. I bought these for cracked sore heels. It took 2-3 weeks but my heels no longer hurt and the cracks have closed and look more like an indention than a crack now. They feel so much better, but I'll probably wear them another week just to be sure they stay healed. They look and feel like regular socks from the outside but only cover the heel with the toe open. Not think but not thick, again like regular socks. They would probably be slippery on a smooth surface the same as socks. The inside feels like rubber or something smooth at the heel. I have washed them once each pair and accidentally dried one pair in the dryer. They still seem to feel the same so I think they're fine. They're pretty inexpensive and had different colors and sizes.

    Truly Helped My Cracked Heels
    Color: Original Grey
    I didn't include a photo cause they look exactly like their advertisement photo. I so liked the silicon-type heel lining as it kept the heel-repair cream on my heel and did not get soaked up by the sock. But, it is so, so slippery when walking around in them! Take care to be mindful when you set each foot down as the lotion can slide your heel across the sock quite a bit. If these socks were for an elderly person, I would have them only sit while using the sock - no walking around for fear of falling. I have larger ankles and found that having both the top and the bottom hems/elastic, etc. the same size to be quite troublesome and was not a nice feeling or fit on my upper hem that hit my ankle. Don't get me wrong, I am so glad that I got them and I continue to use them and they are helping my horribly-cracked heels greatly, but I find that I have to keep moving the top hem up and down so that it doesn't stay in one position as it cuts in to my ankle. My feedback and advice might be to please make the upper hem somewhat larger than the one that is on the bottom and goes over my actual foot. They really should not be the same circumference...or else make different sizes - S, M, L, etc. That's really my only complaint or "con" to ordering these. I think they are a great concept and I like the fact that I can throw them in the washer and dryer.
