I think if you look at the specs closely, the ">1000 ohms" part is referencing the requirements for the high output version of the cartridge. The low output cartridge requires loading greater than 30 ohms. I currently have my 20xl set at 121 ohms on my Nova Phonomena and it sounds very good, but I'm still experimenting as well. I would suggest experimenting with the 75, 125 and 250 settings for starters, but I'm sure others with more experience will chime in.
