Peter showed a new SG -230 at CES (IIRC around $12-13,000) with upgrades to both the transducer and electronics. It is too bad he doesn't have the time to post about differences between cartridge technologies and how that affects playback. It's not as cut and dry as some would have you believe.
But the funniest thing he shared with me was how soon many people are misinformed and spread myths about analog playback and "groove noise." Groove noise is not a physical but electrical phenomena related to the sum and difference reflecting back down the cantilever. The proof is in the pudding as they say. When you hear his new SG-230, LP playback is as quiet as digital. In fact, the background is shockingly and eerily quiet.
Thankfully, all of those improvements will be included in my SG-210 due to its recent manufacture(*ie the last fortnight).
