Yes, I was referring to the internal resistance of the cart itself. I'm running the cart through a SUT set at 30 ohms. The " white noise"-like hiss is mainly through the tweeter and only becomes audible as volume is increased near the peak of my listening range. It doesn't change much if I adjust the gain over a 22dB range nor does it change with different loadings. When I bypass the SUT and use the MC input on my phono stage I still get the same hiss. I used to have a HOMC (2.0mV) cart and it didn't produce any hiss at all through the same phono stage. I'm wondering if a ~0.5mV cart would pretty much eliminate the issue. It just seems to be related to the gain needed on the 0.28mV cart in my system.
