.... I tried my JH Roxannes with the 4-45 and was very impressed -- absolutely zero noise, zero channel imbalance, and suitably low gain to allow me to turn the volume pot past 9:00 before the music starts to gets too loud.
It works with the Roxane ! Without noise !

This is incredible & very good news. I never thought that the 4-45 will be able to do this with the very low impedance of the Rowane.
Do you have some planars to test with ? (I have placed my order for a 4-45, & I have an AlphaDOG and I am considering buying a LCD X)
