I've used them on Traktor Control media. I've used them on vinyl. I've used them on bad vinyl. These needles have never failed me and never failed to amaze me with their sound reproduction. I always wondered why they were so expensive and why every turntablist swore by them. I now know and am wiser for it. Superb stability through the roughest conditions. Though, a bit hefty upfront for the budget minded bedroom DJ like myself. However, the results made me more than happy I spent the money.
