Right now I have a Grado Master, which is a shade better than the Sonata. I had the Sonata and upgraded, maybe I'm now comparing what I'm hearing to the Sonata, but I'm very satisfied.
Most people on this forum don't seem to like Grado, and that has to be because of their choice in music, and what they expect a cartridge to deliver.
In regard to brands, I don't like really high definition cartridges; they seem to bypass the music. Of course that's within a price boundary, more expensive cartridges do both.
Raul, if you can find his thread, gives advice on how to buy and audition used cartridges.
