Conrad Johnson Et3? Anybody Have?

Does anyone have an Et3 that they comment on the sound profile?

1) Is the preamp; ????
details galore, great soundstage & toneally " warm" or " cool"
highs are sweet?  Or more etched?
does it make CDs more listenable?  Etc

2) does tube rolling to a brimar or Millard type tube change its tone to the warm & soothing?  A big change or a little?  Etc

thanks in advance

im hoping the tubes & its profile make it warm & fatigue free with the usual CJ soundstage
