I have a KandK moving coil setup with a Lyra Helikon sl cartridge. IMHO if you find the KandK to be "creamy", you probably need to look at other components in your system. I feel the KandK can support excellent cartridges. It is timberally accurate, portrays room ambience very well, and is fast without edge. (Mine is the 6n1p version just prior to the current 6922 version. No volume control and I installed the black gate caps modification. The main caps are the kimber/cardas combination.)
I discussed the most recent 6922 version with Kevin. If you are looking for a defined focus and a little less room ambience, he says the v-caps work well. If you prefer more room ambience to the recording and more harmonics or microdynamics, then he recommends the cardas caps or the mundorf.
He feels the cardas caps are very transparent and do harmonics and microdynamics great. I questioned this, since I've owned cardas golden ref cables and they are quite dark. Kevin said he was reluctant to try the cardas caps under the same assumption, but at the prompting of a friend, he tried them and says they bear no resemblence to the rolled off nature of the cardas cables.
Anyway, I've enjoyed my KandK phono stage and look forward to building his 6922 kit version sometime. Best, Jeff
