Any comments on Synergistic Research Atmosphere

Ozzy:
The Grounding Block does use small mini pins as imputs. That said my system has significantly improved after connecting my  components such as amp, sacd player, pc computer, sub woofers, Tranquility Bases to the Grounding Block. The High Definition cables do have a greater effect than the standard cables, and I use a mixture of standard and high definition cables.

I think the best way to try the Grounding Block is this: Grounding block with one High Definition cable to the wall plug and one High Definition cable to the amplifier. Then try some regular grounding cables  on other components and perhaps additional High Defination cables.

Do take advantage (as I know you will ) to utilize their 30 day return policy. This Grounding Block is really a system enhancer and for me took a bit of trial and error to decide where each type of cable sounded best.
The good thing is the Block and cables are lightweight so shipping costs are miniscule. Not like trying to return a 70 lb. Tripoint Troy device.

I am a big proponent of the Grounding Block having now put it in my Big Horn system, one Teresonic full range single driver system, and one maxed out headphone listening station.

I hope you will take the time to try the Grounding Block. It has further opened my ears as to what is possible to accomplish with a sound system.

David, Thanks, I value your judgment. I will see if I can get one to try.

David, what worked best for you, chassis or signal ground?

Ozzy:
Thank you for the kind words. I really think the Grounding Block is worth the effort as the sonic benefits achieved are difficult to obtain by other approaches. What worked for me was to start with a Grounding Block with the High Deffinition cable that goes from Block to wall outlet. Plug it directly into wall and no where else.

I then got several regular grounding cables and some High Definition grounding cables for the other possible objects to be connected. I very much liked the effect on the Jadis amp, the Art Audio PX-25 amp and the Zana Deux headphone amp. Here the High Definition cable was worth the premium cost. On the headphone SACD player the effect was too much both regular and premium grounding cable. This unit sits on a Tranquility Base and has been fine tuned with the ECT (Electronic Circuit Transducers) plus the RED fuses.

Got a nice effect on the Computer source (USB connection) for one computer (HP) and on one computer a bad sound like a motor running( Lenovo). On the Antelope DAC via RCA connector the effect was too subtractive.

This manipulating the equipment ground is fascinating and worthwhile.
The thread concerning the Entreq grounding system at another forum site is over 170 pages!
Talk with a Synergistic Research dealer and let them know your plan is to try multiple configurations and what does not work gets sent back.

I absolutely believe That Synergistic Research wants me to get my systems to sound their best,and the best way is to try several configurations. I have not had a problem with their return policy.

If any one want to talk via cell shoot me a message. I talk more coherently than I type!
