The β22 is definitely the more neutral amp here. That being said though, the coloration of the Krell is a lovely color indeed. It's a very full, warmish and somewhat lush signature. Bass is a bit deeper from the β22, but it's not a night and day difference. Going back to the β22 from the Krell almost makes the β seem a bit dry at first. Need lots more time, but no doubt that this is a fine amp, and a worthy choice for the K1000.
