My opinion is very biased (admittedly) but there it goes anyway - I always think that improvements to phono stages are more worthwhile than tonearm changes. I'm a die-hard Graham fan, though I intensely dislike Clearaudio cartridges. They are one of the current fads regarding cartridge brands, but I feel sorry to disappoint you, I don't enjoy the "German" school when it comes to cartridges and IMHO they are amusical devices.
Though "colored" (in a very good way however), I'd stick to a Koetsu, I've never seen anything as musical. The loading can be very strange and very few phono stages will do it, i.e., 10 ohms (yes!) and quite odd pF values, but then I think it is worth every effort. The Koetsu gets out of the way and leaves you with pure music, extracting the best out of even old recordings! The Clearaudio is, to me, an analytic tool, albeit a lifeless one which will not stir my emotions,
