HiFi Trade?
  1. No
Icon Audio passive R in mint condition Inc box, pick it up for £125 which I thought was a steal. Nope the seller was the thief, it was utter garbage, strangled the life out of all music. Luckily I found some muppet to give me £250 for it at Audio Jumble a couple of months later.
don't you feel a little sorry for the muppet?
