As I mentioned, I have a 2i and I purchased Supra CAT8+ cable from seller zendada on eBay. I really am the last one to recommend anything to anyone, but the Supra CAT8+ was noticeably better than the cable that came with my node2i. I don’t know if it was because it was CAT8 or because it was manufactured by Supra which a number of persons highly recommended.
If it was me, in time, I would think about purchasing the Supra, I think you will easily hear the difference. Zendada sells 8 meters for $111 which includes shipping. If I hear such a big difference with my hearing you will also! I mention Zendada, because he has free shipping and is a trusted seller on eBay. He calls it CAT8+, but this is a bit of advertising fluff, it is CAT8.
