My dedicated audio room build - QuadDiffusor's Big Dig

Master Earth Grounding bus bar

This section highlighted in green will be connected to a variety of low resistance ground sources, including wet soil rods, cold water pipe, etc. The main Breaker Box (inside the house) will have a grounding cable running to this Master Earth Grounding bus bar.



A much older house nearby in the same neighborhood has a suboptimal (much smaller, and heavily corroded grounding bus bar mounted on a wooden board) with bare wires inserted. The only good thing going for it are the very clear plastic labels, LOL. Frankly speaking, I have no idea how this bus bar does what it's supposed to do!

Streetside AC power utility box

The local utility company's metered compartment, located just outside my house.

Do you know if the bus bar is aluminum or copper? Europe is lucky in that a lot is copper. The USA and its race to the bottom of the garbage can is all aluminum. You can't even special order copper. Cheap, Cheap, Cheap is all the market desires.

The guy in charge of Mechanical & Electrical works called his buddy who replied that the Ground bus bar was made mostly of copper. It sure look like the following product, a solid copper bar with a thin surface plating of tin. Appearance-wise, it has a similar surface sheen as the one inside my breaker boxes.

Without removing the bus bar and grinding off the surface plating, there's really no way to verify whether its core is indeed mostly copper - fingers crossed that it is! At least it doesn't look like cheapo aluminum...

I've decided on my next DAC: the MSB Technology Cascade.
And, after that, taking advantage of the trade-in program, the MSB Technology Sentinel:

MSB's new Sentinel DAC

Since about a year ago, MSB Technology has been busy developing their new flagship DAC, The Sentinel. As a future owner of this heroically-engineered flagship DAC, I'm absolutely thrilled! I'd like to start this thread to keep everyone on WBF updated. MSB's own website's forum has several...

The swimming pool's been (mostly) tiled, the car porch gate's in, and very importantly, the porta-potty has been moved a bit further away!

The new Soulution 717 power amplifiers are currently my top choice for monoblocks. Excellent exchange of information between Ron and Cyril, especially the reminder that linear power supplies using torroidal transformers and rectifiers which converts powerline AC into DC is essentially an inferior, slower SMPS with no power regulation, whose efficiency is woefully low, and outputs distortion/noise which smack into the audible spectrum.

Thanks, Phil !
Extremely short on photos and diagrams, but I'll try starting with the following website/page:

Phil,

Thank you for introducing the Bocchino connectors to me!
I've emailed the Australian gentleman proprietor, Carmine, and waiting for his reply.

I found the "Sablon Audio" chat site on WBF, and in particular, this forum on power cables has been particularly useful in understanding the characteristics of the Bocchino IEC connector, whose size is gigantic but necessary to accommodate largest of copper conductors and associated python-like "audiophile" cable jackets. Luckily, the space behind my audio components will be quite spacious so the IEC's size should not be a problem.

Sablon power cords

There’s a well known audiophile saying about how good sound starts at the wall and I was always fascinated by power cords long before I started making my own. I literally went through dozens of different models using a variety of materials and topologies. Over time, it became clearer how the...

Like the photo below, I'm likely going to be ordering ten Bocchino IEC connectors.
