My guess is the right setting is between 10 and 30 ohms- Lewm is right about 10 ohms being overdamped. If the load reduces the output of the cartridge, then it is too low.
Transfiguration Temper Supreme cartridge loading
I'm trying to optimize the cartridge loading for my Transfiguration Temper Supreme (which has a 7 ohm impedance) with my Spectral DMC-20 preamp with internal phono stage. There seem to be benefits/trade-offs for the three best settings I have found: 10 ohms, 30 ohms, and 100 ohms.
10 ohms seems to give the most detailed, airy presentation, but with about half the gain, requiring me to turn up the volume control half-way just for reasonable sound.
30 ohms loses a little bit of the realism, but is still pretty open and detailed.
100 ohms loses more of the airiness and detail, but seems to have a better soundstage.
I'm tending to go with the 30 ohms, but I might prefer the 10 ohms if I didn't have to go so high with the preamp volume control. I've seen all kinds of recommendations (including from this forum) regarding the optimal setting. I am getting confused and need some guidance.
