Krell Evo One vs Evo 600e/900e


I’m curious what are the differences especially in clearity, bass definition & depth, 3D and presence. Newer is better?

I haven’t found direct comparison between them. Any personal experience would be welcome.

Have tried Evo 600 and 900 but now I am using Evo One with Evo Two for Wilson Alexia. Evo One is far better amp than Evo 600 or 900. Totally different. Impossible to compare.
dantechoi, do you have any experience comparing the Evo One to the Evo 600e by chance, and if so what are your impressions?
I bought Evo 600s. After speaking with Krell the consensus is the Evo 600/900 have a superior sonic signature, higher output and great power reserves over the Evo one. The Evo one does sound great and looks amazing but the 600 took the cake!
