I got 2 matched pairs of WE 417A from audiotubes.com and replaced Raytheon tubes with these. It has been only a few hours so far but I am impressed. Brent Jessee of audiotubes told me that they were all low microphonics. Lamm LP2 is certainly a lot more quiet now, pretty much on par with Fosgate. I also replaced stock fuse with Power House platinum fuse which helped a lot as well. The sound is clearer, better focus, slightly more open with out any loss of body or smoothness and better controlled bass but perhaps, I miss a bit of the lushness of the Raytheon.
Oh well... I need to burn the fuse and the tubes a bit more but I am very impressed.
I will keep Lamm in this configuration for awhile but I am curious about changing capacitors in Lamm. Not sure if I want to go down that road but just in case, I was told that Mundorf does not make caps as big as those that Lamm uses but somebody suggested V-Cap as a possibility. I wonder for those who have changed caps, what do you use?
