Just a reminder. For those who use or are going to use a Stanton or Pickering cartridge that is going to mount to a metal headshell or tonearm, you must electrically isolate the cartridge from the headshell or tonearm in some way. You can use the elastomer isolation blocks that come with each Stanton and Pickering cartridge if you have them. These are excellent. Some people prefer a more ridged mount, for whatever reason, and so they want to use nuts and screws. That's fine. I'm not going to opine on this practice other than to say that if you're going to go this route, then you have to remove the ground strap from the pin. I have read that you can simply slip this off of the pin, but in practice I have had to carefully and painstakingly walk them off. The section that is under the cartridge body will slide out. I have only walked these off to make repairs to the cartridge and then I put them right back. Stanton and Pickering's advice is to cut the ground strap, but I just use nylon nuts and screws if I don't have elastomer isolation blocks. However, nylon hardware might not hold firmly enough to satisfy those who demand super rigid installation, in which case cutting or removing the ground strap is the only way to go. The only reason I'm bringing this up is because I have grabbed a few cartridges on ebay that were mounted to metal headshells using metal hardware. I tried them as they were and they hummed. Perhaps, if the owners knew better, they'd have kept the cartridges and changed the hardware, used the blocks or snipped the ground strap.
