Has anyone tried the Synergistic Research PHT?

Just curious. Seems like mumbo-jumbo to me, but HIFI is strange.
I noticed differences. The blue one took the sound in a direction I didn't like at all. I nearly yanked it immediately - that's how noticeable it was.

I liked what I heard from the purple one, but the improvement wasn't significant enough to justify the price IMHO. At half the price, I would have popped for one, I think. The purple one reminded me of what I heard from the WA Quantum tonearm chip.
