@lewm Yes, I had heard that this is an option. I might try it.
Honestly, the gain is not the issue through the MC input. I have plenty. And I honestly have zero complaints with the sound of the Steelhead in general.
Just curious if the MSL SUT would optimize the gain for the cart. I guess the only way to know would be to buy one and try it. I tried to buy one when I was in Japan last fall but every store that had a display model would not sell it to me, saying I would have to special order one. I was only there for two weeks so that was really not going to work. Now they seem to be available again, but I don't feel as motivated as I was then. Ho hum...
