Not buying or selling, if they work that’s cool… i have learnt my lessons with cables having huge effects on SQ, why not these. Still would love to know what’s inside. I suspect inductors and capacitors, or nothing, and they simply improve the earthing
I do draw the line at fairy dust and magic audio wizards!
There’s a pressure release valve. When they’re too full, the excess noise will bleed out of the plug. I’ve got a little matte-finish japanese ceramic mug that I use to collect the waste noise; I found that it sounded better than a gloss-finish mug with my GroundArays.
With the two plugs I posted before … one for 552 and the other for nd555 I got a lot of bass that was not before, now I added the third plug to the switch I get less bass…I’m confused and I do not know which is better…so in my opinion it alway change the sound without being sure what’s better.
