Overpowered : no. They're driven since day 1 by the same tube Preamp and Amp custom made for the K-Horn by Yves COhet, one of the best
french sound engineers. The amp is 22 watts.
I switched the L/R cables on the amp : the distortion is still in the left K-Horn.
I changed all the tubes : no avail either.
Clipped signal : no. Beethoven/Serkin and Chopin/Arrau don't send clipped signal…
