The higher output XI cartridge was no problem. If I held my ear right up to the speaker, I could hear a little preamp noise, but at a significantly lower level. The gain difference needed to make up for the lower output of the XA over the XI is 8 dB, so my preamp was right on the edge in terms of noise for the lower output unit. Ideally, I think you’d want something with closer to 70 dB gain for the XA and 60 dB for the XI. I set loading to 1 kohm. A-T recommends loading of at least 100 ohms. I did a little experimenting but decided to limit variables and just leave the loading at 1k for the test as I was happy with what I got. But you can experiment to your heart’s content.
