It was when Jimmy told me that PB reached out of his window and "polarised the moon" that I began to have serious doubts as to JMH's sanity...
Sorry, I was eighteen once and took in almost every new thing I was shown. Only later did I start to question the more outlandish things and yes, I still have CD's with green and black pen marks round the edges, others with bits of foil stuck on them and some magic safety pins with assorted washers and nuts on them hidden away somewhere.
One of the best "upgrades" I made to my Meridian 207 CD player/preamp when I had one was to make up some "shorting" phono-plugs with the wire some centimetres long and with a reef-knot in the middle. I used to routinely tie a reef knot in all our mains leads too. The shorting plugs plugged in to unused inputs on the Meridian did seem to improve things a tiny bit.
Tear down these walls; Cut the ties that held me
Crying out at the top of my voice; Tell me now if you can hear me
