Purchased new from Music Direct in 2007. I figured I would try it and send it back with the 30 day return policy if it didn't make any difference in the sound. Well I still have it 5 years later. At least in my system this power conditioner improved every aspect of the sound. Primarily it lifted a muddiness that I had never knew existed. There are plenty of reviews out there as well.
I am downsizing my primary system (child, no time etc) so will not be needing the Hydra. It is in great condition although I am rating this a 7/10 for age, now 5 years old. I am including a Shunyata copperhead power cord that I bought for this unit (it does not come with a stock cord) which itself was $350.00. If you do not want the cord I can adjust the price of the unit accordingly.
I will cover shipping and fees at my asking price, otherwise we can negotiate these.
