I had the opportunity to pick up a used Eddie Current Aficionado with a full complement of NOS tubes for $3000 and I pulled the trigger. All I can say is that, paired with my Lynx card and Sonic Frontiers SFD-2, this is my endgame setup. I'm done. This is pure bliss with the Eikon. Dynamics, clarity, resolution, imaging, SOUNDSTAGE. Everything is on a different level from any amp I've had before. I even had an IHA-1 for a short period, albeit with hum issues. Very good amp but this was worth every penny of the extra $1000 I spent.
Now to start looking at vinyl rigs and efficient speakers...
