I also heard from someone who suggested that if good power cables are used, it may not be necessary or better to provide additional grounding with a separate cable. I’ll try the one with the separate grounding boxes first.
It’s a bit confusing whether ground is connected or floating in a component. Many factors that must be taken into account to get a good result. Luca can remove a cable bridge from his components. My Farad Super 10LPS has a switch on the back to disconnect or connect the ground.
But what about the other components? When I ask my dealer, he is stumped. When I told him that I wanted to replace the XLR protective caps that put the signal ground on the housing because I might create an unwanted ground connection, he looked at me perplexed.
Theoretically, you could use a CAD box with two connections for a component to connect the housing and the signal ground separately. If there are two separate compartments inside the CAD box, you only use half of them.
Nope. CAD is clear on this argument: never connect ground and signal to the same GC otherwise you create a connection between them. Inside the GC1 there isn’t separation at all.
If you use just one wire, the entire GC1 job is focused on that component. It is working at 100% for that purpose.
If you connect two devices the GC1 has to work at half its potential on both.
One more thing: you can double the power of a GC1 if you connect in daisy chain another GC1 via a ground wire terminated with banana 4 mm on both ends. It seems to me overkill though. But it is doable.
My order seem to be arriving little by little. Yesterday I received a round grounding box. Since the color matches my preamplifier, I attached it to a screw on the housing. I’m still waiting for more.
The thing reminds me of a vacuum robot. Below are ceramic balls that have a spring action. The workmanship is really very nice. Does it make a difference tonally? I still have to do a comparison with the other two boxes that are still on the way.
Hi Donald, I installed the three Xangsane ground boxes today. Two with the silver RCA cables to my DSD Mk2 and BHK Pre, and one to my Mac Mini (BACCH). I was too impatient to do the one by one (too much to do before Christmas, and I’m heading away tomorrow). Suffice to say I’m pleased. Lower noise floor and seems a more natural presence. Not earth shattering but nice. I’ll let it settle. I’ve also ordered three of those HIFI Audio Power Noise Absorber EMI Filters you mentioned to complement the two VeraFi Mainstream noise harvesters I already have.
This question is for Luca actually. I have MU2, DS MK2, and LHY SW-10 connected to signal ground (three Xangsane boxes), PST, LHY SW-6, M1200 and PZ all connected to chassis ground using RouteMaster.
Now I have some empty slots available on RouteMaster, so potentially I can connect chassis ground of MU2, MK2 and SW-10 to it too. The question is what will this gain? Will it make SQ worse?
I put 6 Puritan Green cables on sale, and they were all sold withing a day or two. There must be a ton of users out there. Now I cannot even try the above anymore. Sometimes I should think a bit more before making a hurried decision.
Donald, you are very spontaneous in your decisions. I can’t help you with that because I only connected ground boxes and no star grounding. I hope your family noticed the outstanding sound. My brother visited for Christmas and he was very impressed when he was able to listen to his favorite songs. In contrast to his last visit, I have changed a lot. He said it always sounded good, only now it was even more realistic and instruments could be located better at their height than before.
My brother isn’t crazy about audio, but he plays several instruments. Mainly Old English horn and oboe in an orchestra.
He heard things in his favorite songs that he hadn’t heard before. I just didn’t want to tell him that the changes that were necessary made up the price of a small car.
Here is one of my brother’s music tips. The film would be good too.
We had 12 people for dinner last night, the dinner went great. We had beer, Moet & Chandon, Dunn Cab. too. My audio system finally got some great attraction. After I showed them how to do search in Roon, the kids started to use my system for Karaoke. They all used their phone to get the lyrics from songs and started singing along.
Still, no one cared about sound quality, but they all said the system was great!
What? Drunk crowd with children in my listening room! That’s a crazy and dangerous idea indeed!
I shared my room with only one person (not an audiophile) who still invests most of his time and money in LPs and live concerts! It was a fun hour of pure joy for both of us. And yes, we had already drunk a couple of Magnum bottles of Bellavista.
Don’t think you’ll miss those green wires, to be honest.
You could sell the RouteMaster soon.
One ground box for each device is the right way IMO, signal ground first (MU2, MK II, PST, switches) and eventually chassis ground just for PSUs (if any) .
Star grounding for PZ and M1200s can be made using just 2 ground wires, no ground boxes in between, connecting each amp’s ground lug to the PZ’s one.
Question to the great specialist in grounding.
I have just connected a Nordost Qkore1 to my Furutech Vault power strip. As expected, this brings silence.
I would like to know if it would be relevant to connect the amps to the terminal of the Furutech Vault power strip ?
Thank you in advance for your answer and I wish you a very happy New Year’s Eve
