Well I bit the bullet and gave it a shot from the dealer. Its actually the step up version which is the hydra v-ray. I noticed a difference right off the bat. The imaging and noise levels improved, but at what cost? My rgpc is $800 where as the v-ray is a whopping $5000, and another few hundred on top of that for the python helix cx pwr cable. Although there was an improvement, it really is only about 10-15% better than the 400pro. I have a sneaky suspision that when I get my rgpc 1200c there will be an even better improvement than the hydra. Don't get me wrong, it is an awesome conditioner, just too much money for what it is. Plus the the rgpc can do the whole breaker and not just one ac line, and its twice as cheap. Just my $.02
