The K&K gets my enthusiastic recommendation. Others I have owned that were not as good:
phono stage of AI 3A
phono stage of Cary SLP-98
EAR 834P
Sonic Frontiers SFP-1
Bluenote Pamphili
phono stage of JJ Electronics 234
Those last two were close, but the K&K is still better. It has just enough tube goodness, but not overly so. And dynamics and slam are excellent. I don't think you can go wrong with this one.
