Ca2284,
First, the recommended impedance for a LO ZYX is 100 ohms or above, not 100 ohms specifically.
Second, I am not aware of many LO ZYX users who prefer a 1K load. Virtually every owner I've talked to (dozens) is somewhere between 100 and 250. My LO Airy 3 was in that range, as is my LO UNIverse.
Cello's sonic description of too-high loading was correct as far as it went, but an addional effect can be a looseness in the bass. However, I'd expect that simply going from 100 to 200 would make these differences in a fairly subtle way. My preamp has a switch and its present (soldered in) resistors are for 75 and 225 ohms. In our system 225 is better, and close to optimal. I wouldn't go any higher, and once in a while I switch to 75 to tame a really hot LP, like some of the tipped up Classic Records reissues.
You should experiment of course, since your phono stage makes that easy. That's a good feature. BTW, make sure to use the same resistor type for each value. The differences between resistors in this application are quite audible.
