I've had the Krell 300i and the Creek 5350 and I can safely say, it depends on the speakers. I absolutely love both of them. With Sonus Faber Electa Amator 1 and Concerto's Krell was best, with Sonus Faber Signums and Silverline SR 17's the Creek was best. The difference is significant. The Creek offers a very listenable phono stage as an available option, and it is just fine for my Benz Glider and Rega P3 table.
So my advice is pick your speaker and ask again, or buy either one and try some speakers.
