Synergistic Grounding Block and Tweaking it.



Synergistic Grounding Block and Tweaking it.

I always liked the Synergistic Products and I have to give them credit for bringing out some of the most unique tweaks available today. There interconnects, speaker cables, and power cables were always top notch, perhaps a little pricey, but I always hated all of those extra mini couplers wires! So, I moved away from their wires. I think there new series does away with the extra mini couplers, but they are still IMHO still quite pricey.

I wanted to try the Synergistic Grounding Block. The price was not too expensive, so I ordered one from my dealer. Did I mention I always hated all those darn extra SR wires? This grounding block better impress.

Once I received it, I couldn’t believe the size of it. It is about 6 “long and maybe 1 ½” thick and about 2” inches high. At one end it has a hole for accepting a regular size banana plug and on the top there are 18 pin hole openings. The grounding block comes included with six (6) of the skinniest wires with the smallest banana plugs I have ever seen for grounding! There is also included another skinny wire that is connected to an AC plug (ground only) that plugs into the wall outlet with the other end having a standard size banana that connects to the side of the grounding block.

Well, since I only own one other SR product, I changed five (5) of the rest of the banana plug ends to RCA so I was able to try it with my own non SR equipment.

To my surprise, it did indeed make the soundstage purer and deeper. I don’t understand it? All of my equipment is plugged into dedicated grounded outlets, so why would this little diminutive grounding block with all those skinny wires do more?

Now, the tweaker in me took over. It seems SR also sells higher grade connection ground cables, but boy, are they pricey! Two of them cost more than the block itself! And the Synergistic grounding block can accept 18 of these ground connections!

I had some pure .9999 22 gauge silver wire left over from another project so I installed an RCA connector, sleeved it through some Teflon tubing and pushed one end into one of those 18 pin holes in the grounding block. To keep the wire from falling out of the pin holes, I pushed cut 2” lengths of some .999 18 gauge silver wire also into the pin hole which tightened up the connection. On the end, the RCA was connected to an unused RCA on my equipment. I also had some pure .999 16 gauge silver wire, so I installed this on one end with a regular banana, and then installed an AC plug (ground only) to the other end. This replaced the skinny wire that SR supplied to connect from the wall to the grounding block.

Sounding better… interesting!

On line I found some 12 gauge .9999 silver wire about 6 foot long, that cost about $50. But with this cable, to keep it pure throughout I used no connector on either end. I did this by shaping the wall outlet wire end into a V and pushed it into the wall outlet for a tight fit. The other end was crimped tight and shoved into the regular banana hole into the grounding block.

Each “upgrade” in wire went through a minor break in period. (hours not days) and doggone it, it did increase the purity of the sound.

So, now with the 18 available pin holes in the grounding block, I have all of my system connected. That includes my video and subwoofers!

Someday, I would like to try one of the higher grade SR cables to compare to my DIY version.

Folks, this little grounding block does work wonders and far exceeds the price to performance, but it is still a mystery to me. Plus all those darn wires!

David,

Well I now have 18 things connected to the block. So, buying the SR High Def ones would be too much $$$. But, there is a difference with using better wire. Most of the wires I am now using are solid pure silver either .999 or .9999.

The main wire going to the block is 12 gauge .9999. I think you should try a heavier gauge there, you will be surprised. I have one of the Mad Scientists tubes on the grounding block I will try the Discus. I am also thinking of trying a SR HFT on the block.


One more thing. I have the ground wire going to an outlet outside of my stereo system. I think it sounds better.

ozzy:
Absolutly agree that the wire matters in optimizing the Grounding Block's effect. I am glad your DIY efforts are paying off. I just noticed an error in my post. I am (like you) using a Mad Scientict Tube Topper on the Grounding Block. I got the Mad Scientist names wrong!

I still need to try two Tube Toppers ( one on each end of the Block), a HFT, and an ECT on the block.

That is an interesting observation on having the ground wire going to a wall outlet separate from the music system. Now we will need dedicated audio circuits and dedicated audio ground circuits!

Keep up the wonderful work and valuable and educational reports.

Ozzy:

I tried two Mad Scientist Tube Toppers on the Grounding Block.

One Topper sitting on top of the unit at the end where the grounding wire goes to the wall outlet is (for me) the optimum location and number of Toppers to use (one).

I am already using approx. 7 ECT,s on the amp, SACD player and Transporter. Total ECT's for system.

We did a survey about a year and a half ago investigating these devices. The owners had to be able to do a measurement on the associated equipment in there system. What we found was an interesting correlation- in all cases, when the grounding box made an improvement (as reported by the owner), it was also found that the associated amps, preamps, etc. had a bug in their grounding scheme somewhere. In some cases the gear was not grounded at all, in other cases the chassis and circuit grounds were the same thing (susceptible to ground loops).

Quite often the use of a video device messed things up- it turns out that video units like TVs have poor grounding practice as relates to audio systems.

At least one manufacturer of grounding devices mentions right in their owner's manual that if proper grounding design is observed in the equipment that the grounding device might not have any effect.


atmosphere,

Interesting comments. Not sure if I concur with your conclusion. Have you actually tried the SR device?

I will say the improvement continued as I added more and more components to the grounding block. That does include my video sources.
