Primaluna Diaglogue Premium Preamp Owners

I have had a PrimaLuna Dialogue Premium Pre that fronts for a McIntosh SS amp and a pair of Martin Logan ESLs for a little over a year now.  I only used the stock tubes for about a month...  They sounded great after run-in but I have not used them since rolling in two 12AU7 1962 vintage MAZDA CIFTE tubes sitting in the drivers seat for the first gain stage, four 12AU7 Genalex Gold Lions in the second gain stage and cathode follower output stage and two Genalex Gold Lions 5AR4 rectifier tubes and AudioQuest power cable and interconnects.  In my system and in my room it sounds like magic.

I feel that in my system, the GGLs bring higher highs and lower lows... Extension, resolution, speed and a tightness across the frequency range... The CIFTEs bring an edge, air and sparkle to the top... When everything comes together, in my listening space, I feel like I am in the venue the music was recorded in... Lush, rich, 3D and holographic...
