EMT and SoundSmith

I agree with everything @millercarbon said but wonder how many SS owners actually take Peter up on his revolutionary policy. The typical audiophile likes to change things up, not wear things out. I’m guessing most SS owners sell and move up the line or to another flavor cartridge long before they wear out the tip and send it back to Peter for a rebuild. If anything, the retip policy does improve the resale market for your SS when you decide to move on. 
BTW, just sold my MIMC Star (w/ less than 200 hrs) and am also interested in comments comparing SS with EMT (HSD 006 or JSD 5/6). 

@pops Haven’t yet—still working out possible arm and cartridge combos for my next table. Very interested in hearing EMT and Charisma but have not had the opportunity yet. May also move up the Soundsmith line to a new ES body model above the MIMC Star but will have to decide in concert with arm selection.

Also, to what degree is "jitter" the result of the moving mass of the cartridge versus the design and quality of the tonearm and associated bearings? As @millercarbon knows, Mark Baker of Origin Live makes a strong case for his composite arm tubes and sophisticated bearings in properly controlling the cartridge as it traverses the grooves. I'm sure moving mass is important--makes sense--but wonder how so many moving coils extract performance at least on par with what Soundsmith achieves at similar price points. As mijo says, how low is good enough? I'm thinking reducing moving mass is a worthy goal but not as definitive as Peter might argue. Maybe focus on the quality of the arm is more important?
