Sounds like a good deal, but I'm going to sit on this setup for a while and see if I can't make it sing. I don't want cart rolling to turn into tube rolling. I'll end up buying half a dozen of those little wood boxes Kevin Barett sells to keep technics headshells in.
Sound update: the Platinum seems to exhibit not just a midrange hump, but unfortunately an upper midrange honkiness that reminds me of the W5000. This can be heard strongly on male vocals placed prominently in the mix and some higher pitched horns. This wonkiness is much more noticeable with the GS1000 then with the 22Ls. My latest tweak was to set my arm height to zero, which I did when I found out the height of the Platinum is 15mm. This did a lot to bring out the bass and further flesh out the mid-mid range. I was delighted to see my cart riding the pizza with the front of the cart slightly higher then the back, as most of the reviews I've read say that this is the best way for this particular cartridge to ride (most of the time we want the cart to ride evenly on the surface), and that Grado woodbodies are particularly sensitive to tonearm height. I would agree with this statement.
So far the PH-1 + Platinum combo isn't a pure winner. It has some faults (upper midrange honk, grado wooliness) and some strengths (great midrange, decent bass, great soundstage, smooth and pleasing sound, nice steady PRaT).
