Max, it's kind of a bad answer, but experience guides me in this one. Linn pretty much taught us all in the early 1970s that a very inexpensive cartridge on a very good turntable will sound way, way better than the other way around. Right now, your phono replay system is very well balanced, all of the pieces performing to an equivilent level. This is not to say that improving the phono cartridge will not improve the sound, it is just that it will not give you the maximum return on investment, or bang for the buck as it were. An analogy might be to take a nice, high-value automobile, like a Honda Accord, and put $800.00 Firestone racing tires on it. It may handle a bit better, or not, but it probably is not the best way to allocate funds. Probably better to bank the money and start saving for the Beemer, or Lexus, or whatever the next step is. Just my thoughts, hardly gospel.
