I thought I would update my initial impression of the Blackbody units I commented on from 3/17/10. I would like to confirm the reviews recently posted on 6moons. I had repositioned the units to face North through my amps, DAC, and transport with marked improvement. I noted even less harshness in the music, more defined base, and a greater sense of the space in which the music was recorded. There was a more relaxed, natural feel to the music. More recently, I had the privilege of participating in a trial addition of more Blackbody units to see if " the more the better" was true. To get the best sound is truly a trial and error process. I first added a 2nd unit to the DAC again facing North. To my amazement, there was a very noticeable change in the music for the better. I have a Lessloss Firewall positioned in a North/South plane. I pointed a Blackbody, again facing North, at the end of the Firewall. I couldn't believe the improvement I heard! I tried a 2nd Blackbody on the Firewall and again noted a change, but the effect was not for the better. In fact the sound, although very smooth, seemed thinner. I added a 3rd Blackbody to the DAC with more improvement, although not as great as with the 2nd. I tried adding a 2nd Blackbody to the transport with a slight improvement. In total I added 4 units bringing the total to 10. I next subtracted 2 units, one from the transport and one from the DAC and placed a 2nd unit on each mono-amp. I really like the sound with this combination!!!! The music just locked in! Dynamic, clear, pure, detailed, natural, spacious, just a joy to listen to. The music was so smooth I tried turning it up pretty loud. The result was a really visceral experience without hurting my ears or giving me a headache. I just can't believe I'm getting this kind of music out of my 14 year old speakers and amps. I now own 10 units. I purchased them on the spot. In summary, I have one on the transport, two on the DAC, one on the Firewall, two on each amp and two on top of each speaker pointing down (I couldn't position the speaker Blackbodies North). The sound is amazing. I have upgraded my system numerous times since I became an audiophile in 1995. I have never had such an improved sound with upgrades as I have experienced with the Lessloss products. I am looking forward to the "Tunnelbridge."
