You will undoubtedly get several responses to your question, but fwiw my experience with these two amps had the Krell an unqualified winner over the Plinius.
In fact, I traded the Plinius to get the Krell, and have been very happy since. I also think the Gallo will mate well with the Krell.
I have never really understood the hoopla over Plinius, and side by side, this was not close on any dimension.
I also think that you will be hard pressed to notice a difference with this krell relative to the separates you mention. At 2x this price point, sure , but not here. Good luck.
