Lamm ML2 power cords and tube rolling


Am interested in any recommended power cords which seem to work well with the ML2; also, tube-rolling experiences, in particular regarding the 12AX7, would be most appreciated.

ON PCs, I really like the Kubala cords on the ML 2. That's what I'm using. And, I get my tubes thru the mad Russian in Brooklyn.
I am using Silent Source Hi Current power cords from Walker Audio with good results. In the 12AX7 position I am using a Raytheon black plate O getter which I found better than the Tele smooth plate. The Tele had a nice midrange but was light on the low end in my system.
I use the Oyaide Tunami Power Cords.A friend compared them with those from NBS (don't know which model) and prefered the Oyaide.
