It seems to me that some members that replied to this post don't have any experience with the Blackbody and wanted to push the Blackbody to the esoteric absurd voodoo tweak. Louis explained nearly every little detail on the creating process, theory and technical details extensively that no other company would do. So it's all particle physics and a lot of brain work gone into this product. You can only judge it by trying it yourself. And Louis gave you the opportunity to try the Blackbody and give it back, if you are not satisfied. You can't go wrong. I purchased one Blackbody and don't want to go on, listening without it. The differnce is not subtle or belonging to your imagination. With only one Blackbody the complete sound reproduction shifts to a new reality. Especially on records or CDs that sounded excellent before, the improvement was sort of, yes... unbelieveable. With my first try i invited a second person with bats ears, very critical to such tweaks. We sat there for hours listening, back and fourth, with or without the Blackbody. Approved, it is no illusion. Any sound aspect thinkable was improved, wonderful! Also you don't have to have equipment in the 100K or above range to realise the difference. You probably won't go for a device at this price when you have a 2000 $ stereo. But i'm sure even there it would make a big difference. You can spend a lot of money on tweaks, and some will only affect a special frequency range. Think of all those room treatments available. Corner traps, bass traps a.s.o, how far will you go with these, when you can reach similar or better results with one device like the blackbody with it's modest size? Anybody out there who expected a new product by Lessloss that is untrustworthy? I'm gladly looking forward to the introduction of the Tunnelbridge and the new Firewall power distributor.
