My Marantz tt-15 is made by clearaudio and uses the Satisfy arm. Here’s what I’ve tried:
1. Concept MC cartridge: a perfect match for the arm, the Concept MC gave a nice present sound with a crisp (not too bright) top end. I put so many hours on it, I retired it for a
2. AT-VM740ml moving magnet cart. Very nice balanced sound, better bass than the Concept, maybe a little less presence than the concept. A very satisfying experience. However, I missed the MC presence so I then moved on to a
3. AT- OC9x ml. This is a fine cartridge, especially in light of the price. I’ve had it now for about a year ( maybe 300 hours ), and it’s sounding great on my Marantz. If I had to replace it tomorrow, I would buy another one. Also, Audio Technica offers a trade-in program credit for new cartridges. ( in the USA).
The rest of my system- Vintage Signet Step-Up transformer, Hagerman Comet 3 phono pre, Marantz PM17 mkii amplifier, Monitor Audio Silver 100 6g.
