For several years I ran 2CEs with a Conrad Johnson CAV50 ("control amplifier", 4XEL34 based, passive pre,~37 WPC) as my first foray into tubes for a second system. Really enjoyed the laid back sound for late night listening, quite revealing yet very gentle on the ears. Zero beaming or screech across the bandwidth. Loose but full bass sounded great with 60s', 70s' production values. I do miss those 2CEs.
