so… I picked up this cartridge couple months ago before it was available in Canada. My boy got them in Miami for me & I’ve been using them since like the 2nd week of May. I decided to just get the OM’s not the Concorde’s as I could use headshells from before & other dj’s I spoke with said OM’s are better. I’ve always wanted to get Q-Bert’s or Ortofon cartridge’s as when I’ve used them in the past, were phenomenal when djing.
  
I spin roughly at least 4 times a week at clubs & the sound was crisp & it was very tight when cutting/scratching. Recently however, the actual needle on both of my stylus’ came out! I was unimpressed at that as that has never happened to my M-447′s EVER!
  
So either I may try a Concorde or Q-Bert or just stick with my good old M44-7′s, unless Ortofon decides to send me some free needles. lol.
  
Let me know your thoughts on yours if you have a pair.
