So far I have used the T2000 SUT with the MC3000 cartridge since its installed and aligned on a headshell. The MC2000 is at Expert Stylus getting a new diamond put on it and a general cleaning and tune-up. I need a set of headshell wires to install the MC200, and that is a pairing I am really curious to hear.
With the MC3000 the sound isn't too far off my better cartridges. While not the same sound, and perhaps lacking the finest bit of detail in the upper registers, its at least in the same ballpark. It's like they had worked out what the sound should be like, and have spent the following years refining it and getting output voltages up to higher levels and retaining that overall presentation. I imagine that is no small feat, going from ..05 mV in case of the MC2000 to .10 mV with the MC3000 and now to cartridges between .30 and .40 mV in the current lineup.
