I use quartz and other complementing minerals on my cables for years already...
Low cost cables modified at peanuts cost...😊
If someone doubt it it is very easy to verify using alternatively shungite which will compress sound and quartz which will decompress it ...
All the craft is establishing the right balance ..Other minerals work each in their own way positively more or more negatively but way less audibly manifest than quartz and shungite which are complementary opposite ...
I dont spoke about that here usually because this attract objectivist ideologue and sleeping brain attention on me a bit too much ... My temper is too reactive ...😁
By the way i never bought any tweaks... I designed mine ...i said it for some non creative narrow minds...
And remember no tweaks can improve a system over or instead of acoustical,mechanical and electrical working controls...
Especially acoustics...
For sure we are not all here owners of 100,000 bucks system who will mock "tin foil hat" with like myself tried to maximise a low cost system ... But nothing is more instructive than people affording high end gear who do not know how to stop upgrading because they never learn how to embed their gear in the electrical,mechanical and especially acoustical dimensions ...
Perhaps myself with a 100,000 bucks system and 3,000 bucks cables i will not have the idea to put some minerals on them ...
Creativity is more fun than purchasing ability ...
You dont buy intelligence you work for it ...
