Stewart0722, have you considered tube rolling into your CAT? I did this on mine and it went to an entirely different level. Rolling NOS tubes into both the line and phono stage was a huge improvement.
Not sure of the iteration, but there's an SL1 on gon now that has met it's reserve at 1150.00
I have never tube rolled my pre. Ken Stevens hand picks my tubes and I pay dearly for them. The last two sets have been dead quiet.... A warning.....this is not a pre you can leave on 24/7. It is basically an all out assault hot rod and will eat tubes like no tomorrow.....
