There's not much info on the Two, but the One is spec'd at .28mV with a VTF = 1.5 - 1.8 gm. The load is spec'd at 30 - 47K ohms, which doesn't tell you a hell of a lot. IMO, establishing the proper load has everything to do with good sonics, and you can usually find a good (starting point) optimum load by multiplying the coil resistance of the cartridge by 25. Unfortunately, its not listed. You could measure it easily using a sensitive volt-ohm meter. Most cartridges fall somewhere between 4 - 30 ohms or so.
In the absence of the right info, I'd take an educated guess that it's around 30 ohms, because manufacturers typically use the coil resistance for the low end of the range (in this case 30 - 47K) If I'm right, a good starting point for your cartridge loading would be around 750 ohms plus or minus.
On the other hand, it could be much lower than 30 ohms since it's such a low output design and probably doesn't have many coil windings. My advice would be to start around 400 ohms and if the bass is muddy, increase the load until it's clear and defined. If it's lacking bass and the highs are glarey, the load is probably too high. Reduce it until you get good bass response.
