Seems to me that your phono pre-amp is now out classed by everything else that you have updated. I think your idea of upgrading the phono pre to the Ear 834 and upgrading the cartridge is the right way to go. The Ear has lots of good press and the units go quick on Audiogon. The Space Deck with the Bellari would not be, in my opinion, a good match. Also, if you jump up to the Space Deck, it may cause you to start the process of componant matching all over again: pretty costly. But, hey, isn't it fun??!!
Good luck.
