Plinko, I will try to answer your question and address your comments to the best of my limited ability.
1- re: the Soundsmith cartridges - I do not believe that there are any differences besides the coil detail. Having said that, since Soundsmith is also offers a premier cartridge re-tipping service there are opportunities for customization. One can select between a variety of stylus tips.
2- I think that we can both agree that the DL 102 was designed to output a single channel (mono) signal. As you have suggested, the common practice is to connect both channel leads to the single signal pin on the cart. The problem with this, of course, is that by passing the high output of a single channel to both channels of a stero preamp you are effectivey reducing the output by half. So it then becomes necessary to increase the output of the phono stage, by either increasing the gain or the volume at the preamp. This leads to more noise. This same problem exists if you utilize a mono switch on your preamp. The dual-coil design of the Soundsmith (and other) mono cartridges mean that you have a seprate mono signal generator for each phono stage channel. This would not be preferred if you were using a single-channel (true mono) system.
3- re: the DL 102 page - I saw the same text that you copied. I can't explain it because I didn't write it, but it seems to be in contradiction to what Denon claims is the intended purpose of the cartridge (mono playback of stereo LPs). Also, if there is no output in the vertical plane why does Denon bother to publish a vertical compliance figure for the cart?
