After you're SURE the cartridge cantilever is still straight and hasn't been accidentally bent, double check your cartridge tracking force, it is easiest to knock out of whack accidentally. The Blackbird tracks at 2g. Then check your cartridge loading, you can experiment with the GCPH. Then adjust your VTA to be a little negative, that is, so that the back of the arm is slightly lower than the front when the needle rests on an average thickness record.
Eldartford has a point when he says moving to the wall shelf (an EXCELLENT idea, btw) may have changed the character significantly. The improvement here usually manifests as more space between the notes, which could come across as more lively.
