Hi samh. My OC9XSL replaced a Dynavector 20X2L in my system. The OC9XSL is quieter with less surface noise. The tonal balance is more accurate. The channel separation is amazing. The cartridge body is threaded for easy mounting.
My OC9XSL is on the new Technics SL-1200GR turntable. My phono preamp is a John Curl designed JC3.
I bought the cartridge at the beginning of the summer and It continues to amaze and delight me. Sinatra, Muddy Waters, Gillian Welch, Bill Evans, Bod Dylan... whatever the music the reproduced sound is always natural, balanced, and lifelike.
When I bought my cartridge there were no hands on reviews and I still can't find one. I gambled and I won. I'm not a reviewer so I'll leave that for Mike Fremmer. I'll just say that this is not my first audio rodeo and I'm very very pleased with the OC9XSL.
