I own both a classe ca400 and a Krell FPB 300. I think you should make your decision depending upon which speaker you choose. I personally believe that the Classe is better built and has a little more flexibility because you have the option to bridge mono. Since you are comparing intergrated units, this won't be an issue. However, I have B&W speakers which sound tonally better when run with the Krell amplifier. Your best bet is to findout which speakers you will run and sample both amplifiers. Cost will also become a factor, I find the Classe products to be a better buy compared to the Krell.
