High-quality silver-plated copper earphone cable with pure silver gold-plated plug, limited edition. Purchased new and listened to for about 10 hours. Compared to the normal version, the limited version's pure silver plug seems to make a significant difference in the spaciousness of the soundstage, the clarity of the resolution, and the richness and expressiveness of the vocals. Just when I thought this was the goal, I wanted to try something even better, so I'm offering this for sale. It's a wonderful cable that's also easy to handle. The Acecomet LTD version features a 5N gold-plated pure silver plug, minimizing high-frequency loss at the socket interface and achieving ultra-high conductivity. It provides excellent high-frequency resolution and superior detail restoration, improved sound transparency, and higher integrity. Midrange vocals are richer, and layering is enhanced. Low-frequency performance improves dynamics, allows for tighter control, and achieves a darker background. Thank you very much.
