Question for DJs who play vinyl in clubs: What’s your preferred Ortofon cartridge? Concorde Pro (metallic grey) is no longer available. Now, you have choice between various models (DJ, Scratch, Mix, Club). What’s your preference? I'm looking for the most reliable model in the club environment: sturdy, not sensitive to feedback, with correct tracking force. Please, don't just tell me that Club is for clubs and Scratch is for scratching. I'm looking for a more in-depth opinion based on experience
