@atmasphere Once again, very interesting and informative..thank you.
Ken uses a SUT that doesn't really have a lot of boost because I think he believes that as the step up increases, the loss is SQ is too great. What i am still guessing at is that the SUT allows for a better synergy with my Lyra as to what it wants to see as a load than the prior 750ohm resistor that I was using. The Lyra has a fairly healthy output for a MC at 0.5 mv and I am sure this is not putting much stress on the SUT. It was not putting too much stress on the phono stage before on my old non-SUT unit. Now the advantage of using an SUT has aways been to me that I could entertain ultra low output cartridges without too much tube noise, by ultra low, I am saying below 0.3mv...which there are quite a few very good ones out there.I wonder if that would be an option with this new CAT model, somehow, I doubt it???
