I don't think there that many for sale now, probably because of the price hike and people having money problems just wanting to get their money out? Who knows!!!!! Well all said and done, I have been living with a Hydra now for the last 2 months or so, and I feel, having gone through numerous power conditioners, that this baby is by far the best unit now on the market. Has made the most difference in audible improvement of anything I have ever heard. When I added also an Ensemble MegaPowerflux and Isoflux to isolate the the digital combined with Electroglide Fatboys feeding my Thor preamp and my Audiomeca MephistoII 24/196 Cd player and the top of the line Ensemble PC's feeding my Lamm M2.1 amps with Audiotekne Interconnects and speaker wire feeding Kharma Ceramique 1 speakers, that audiophile Nirvana that we audiophiles are in constant persuit of, well it just happened. The soul of the reproduced music has come alive in my system, the synnergy is just unbelievable. This is as close as it gets to the real thing, AUDIOPHILE MAGICAL NIRVANA !!!!! baby. I believe the Hydra has played an important role in the realization of this magical musical experience. Sceptics out there don't knock it until you try it, there is none better at any price
