Hey Bill,
Wrote on your system but will comment here, as I'm listening now, that the combo of my clearaudio and lyra helikon is really great. I errantly wrote I'd like to try shelter 901, but meant 5000 (brain fart). I had shelter 501 on and it was also very lovely--a little lusher, but sound-staging not as good. The sumiko celebration is also a good cartridge. For me, the lyra provides very much what you're looking for. I find that it's very even across all frequencies, and detail is sublime.
