I eagerly await what the "100% proprietary design" is  

First, I wish everyone well.

Second, please note I am associated with the product in discussion and sincerely hope readers are not offend that I comment. 

 

Thinking back when we outlined the product description as being "100% proprietary design", we were simply trying to state the main component is not an off the shelf part.

 

As with many manufacturers, the design process begins with extensive computer modeling. In this case, data was entered into MATLAB, https://en.wikipedia.org/wiki/MATLAB. After data analysis, manufacturing specifications were submitted to build samples for testing.

 

The manufacturing specifications included:

 

Transformer core shape.

Transformer core input, (primary).

Transformer core output, (secondary).

Transformer core metallurgy.

Transformer wire gauge and wire shape.

How the wire is wound.

 

Naturally, all is meaningless if the results yield poor measurements and bad sounding playback systems.

 

Respectfully,

 

Tim Marutani

Dedicated line from the main panel to the audio system trumps a line conditioner plugged into a standard wired wall socket every day.

 

Installations have specific requirements unique to each room and playback or production system.

 

Recently, we worked with an electrician that provided a 120v 30A outlet, (NEMA 5-30). The outlet is approximately 30 ft. from the sub panel using 6-gauge wire with a twist at minimum of one turn every 1.0 ft.  The isolation transformer in this application is local with the electronics and provides power for everything in the system. (Each isolation transformer outlet is wired directly to the transformer.)

 

One should note that in room installations using existing electrical outlets may provide benchmark results providing there is ample current.

 

A practical application for dedicated lines from the main panel with an isolation transformer may be for cinema rooms that have a plethora of active and passive speakers.

Great... Now another thing I need to buy.  

Let's say another area to raise one's attention. Everyone develops a system to different degrees for different reasons. This said, perhaps at some point paying attention to the quality of power, ground, and system ground reference may bring much value. It's not a glamorous purchase but when accomplished with engineering may be extremely rewarding.

I hope the readership allows me to share a story.

 

We delivered a 1:0.7 image of vinyl record albums stored in crates to a master picture framer a gave them total design freedom and displayed the framed image in a warehouse room. The illusion from the famed image triggers visitors the urge to remove an album from the crate in the image.

 

Audio playback systems are very similar. In the case of the image, there was a master photographer and master framer. Each step of the process was carefully implemented to create the illusion.

 

The requisites of an excellent power source for audio are:

• broadband low noise out to radio frequencies.
• common ground architecture providing a low impedance physical ground.
• robust system ground reference that places all components at the same potential.
• ample instantaneous and sustained current delivery.
• excellent component noise isolation.

When requisites are compromised results are compromised. One may have quiet power delivery into a room and compromise the outcome using multiple outlet strips that may restrict current delivery or minimize component isolation.

 

Good system engineering in power distribution is a requisite for a system to yield a similar illusion. It allows the system to translate the intent of the recording artist and music producer; the reason we continue to refine our systems.
