Virtual ground for Full-range speakers.
Using brass scrubbers (kitchen items).
It reduces the miscellaneous taste and increases the transparency.

Two dissimilar metals in contact will oxidise. A voltage will accelerate this.

Are you sure that you haven't just created some extra load as a result...?

I would like to see these pictures posted again after 12 months of operation.

Dear DRONE7,

I don't want it to come in contact with the air, so once I make it, I can't open the lid.
I have been using a mixture of brass scrubbers and stainless scrubbers for a year and a half, but there is no problem.
After using it for about half a year, the sound will become familiar.

Galvanic corrosion and galvanic currents had become a topic on Japanese SNS too.
If we think about these things, we can't use connectors.

Correct, terminations are all weak points, so industrial type is best overall and the fewer the better, so I've historically hardwired the speaker, leaving only the amp connection with larger systems.

Hello Nandappe,

Is that your Softone Model 8 in the post #9 ?
How would you describe its sound?
Is it popular in Japan?

Thanks

Dear Andrewbee,

I'm using two 300B tube amps.
Model8 is for beginners, but I think the sound quality is good.
However, since it is not advertised by the garage maker, its recognition is low.

Dear nigelwright7557,

In Japan, the virtual ground volume is necessary at least 100g, and it is said that the larger the amount, the higher the effect.
It looks little metal in the photo, is it effective?
