I am a big fan of Grado and I thought the Blue (at $80 a few years ago) sounded terrific with my PF-800, which is a very similar deck to the 1000 and has what looks like the same arm. I'm using a Sonata on my Systemdek IIX right now and wonder if that might be a great match on yours.
Mig: I placed my PF-800 on a barely-inflated 16" (bike tire) tube, which brought the bass back in a big way! I think the suspension on mine may have been a little old and creaky and didn't give the intended isolation.
