Product Summary

The Atlas Zeno Harmonic SC 1:2 Grun is a reference-class balanced headphone cable engineered to unlock the full potential of high-fidelity headphones. Combining ultra-pure solid-core OCC copper conductors with a true dual-balanced topology and the Atlas Grun Coherent Earthing System, this cable delivers exceptionally low noise, outstanding clarity and a wide, natural-sounding presentation. Designed for demanding listeners seeking the highest performance in headphone systems, it provides a significant upgrade over typical manufacturer-supplied leads.

Our Trustpilot reviews

★★★★★
What an amazing company. Anna in the Glasgow branch has been so informative and helpful with my order. Sam in the Aberdeen branch has an incredible knowledge of older amps and speakers.
Alan

★★★★★
I bought a full system from the Aberdeen shop. Christian was very attentive throughout the whole process. I found that all the staff in the shop were both knowledgeable and helpful. I would strongly recommend Holburn Hi-Fi to anyone thinking about buying a full or part Hi-Fi system.
Peter

★★★★★
Jesse is very professional and always happy to help in the Glasgow Audio store. He is very knowledgeable about the products. Highly recommend.
Kyle

★★★★★
The guys at Holburn Hifi were fantastic from start to finish. Explained everything clearly and in simple terms which I really appreciated as I was lost amongst all the info I had seen online. There was no hard sell and certainly an understanding of my budget. I can’t recommend Holburn Hi Fi highly enough. Thanks to Ian, Sam and Christian.

★★★★★
Dropped in not really knowing what I wanted. Sam was most helpful, steering me towards a solution, and avoiding going over the top. From that we moved on to updating our wifi coverage towards a network. Here, Alain was equally helpful.
