Get the GCPH and Cadenza Red. Both sound extremely good; I've had both the GCPH and the predecessor Ortofon Kontrapunkt ("a" and "c") in my system, and have fond memories of them. I've also extensively heard the 2M Black, which is an awesome cart - but the Cadenza/Kontrapunkt is better if your phono stage can handle a low-MC, and the GCPH surely can. The Kontrapunkt/Cadenza line is fantastically musical; my hangup on the higher-end Jubilee/Windfeld is that they're too analytical...and kinda bright.
I'm also a tube fanatic, and I'm not sure you're going to significantly outperform the GCPH without spending much more money OR stepping up to tubes.
