The bi-wire links on Harbeth speakers are plated by a watch-maker and here is a short video of my visit to his clock-repair workshop where he has a pair of P3ES. I collected a batch of links from him.
Unfortunately, the camera's sound quality is 8 bit and I cannot generate 16 bit quality in post-production. As mentioned in the HD video thread, once data has been discarded, it's gone for good. I will re-make this video in the spring, when the weather improves.
