Reference 3A Grand Veenas vs Avalon Eidolon

I have heard Avalons demoed using Boulder amps only. The resulting sound was quite unique in terms of tonal balance and detail. Lots of detail and energy through the midrange I would say. It was also a fairly brief demo. I cam eout thinking there was something unique there that some would consider worth pursuing but also that I would be most careful about overall synergy and performance in order to avoid potential fatigue factors. Lots of potential...but the jury is still out for me.

Apples/oranges really, but my impression is that both would play more or less in the same league and each have their fans.
