Surfing on the lake of fire
No, I'm not referring to some American solid silver hyperlitz 8" diameter stuff at £15000 per foot, but to a colleague's experiment some time in the 1980's. At that time the linear crystal craze was in full spate, my colleague decided to go one better and have monocrystal speaker cables. For this he used plastic tubes filled with mercury (he worked in a large laboratory and had access). They were not a great success, the cables had an impedance of around 2ohms, sounded "crap" and even worse the mercury started to leak through the plastic.
