Any comments on Synergistic Research Atmosphere

Mookie:
I would suggest Auditioning the Synergistic Research level 3 cables. But before changing-upgrading interconnects and speaker cables, please try the Synergistic Research Grounding Block in your current system.

Looking at your system with two powered sub woofers, digital front end, and amp, I am confident using the Grounding Block will greatly improve your system. Also the Atmosphere cables achieve their best performance when they are in a system utilizing the Grounding Block.

Also I hope all who read this will consider trying audiograde fuses and A/C wall outlets. I have tried Oyaide, Furutech, and Synergistic Research. All are a significant improvement over original devices.

I do like the fact that Synergistic Research offers, supports, and encourages you to utilize their  30 day audition and return if not happy with the sonic change.

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?
