stereo5 nailed it for Krell vs DR-9, although I find the Krell enjoyable and it will indeed give you absolute control over the woofers. I have the FPB-600c and the DR-9(s) and prefer the latter; sweeter, more delicate, lacking in nothing to my ears.
Two things re: the DR-9: 1) Make sure you are using the single ended RCA inputs and not XLR. The latter was a design afterthought on early Classe’ amps (Reich used a cheap opamp to convert to XLR) and sounds dull and closed in vs the SE inputs. 2) About one year ago, I bought three DR-9s within a week of each other. Two from one seller and one from another that had installed the Classe’ refurb kit (new main caps and different power transistors). The latter sounds much better than the other two "stock" units. Not even close. Much more open and dynamic. The "dark" sound is gone. Suggest you contact Classe’ about getting your DR-9 updated with this kit and hold off on the Krell.
Best to you thehorn. Whatever you do, DO NOT sell that DR-9.
