I have discovered one year ago that cleaning contacts is very useful for sound quality. Was not believing in that before.
So I cleaned all .
But now I am wondering if it’s useful to clean power cables contact, or only cables going into components and speakers.
I feel it’s yes, but as my powerblock has a difficult accessibility, I would be glad to hear no.
I’ve always felt it helps from low-cost tweaking with older cheaper systems but is a bit of a chore.
The question that I think we now have is do cleaners of any kind leave harmful non-conductive residues even if the oxidised pins on the leads looks nice and shiny after cleaning.
I bought recently the Audience 24U SX speakers cables. Inside the box there is a cleaning fluid dedicated for that job. So I feel they know well what they advise. I hope so.
6 months ago I cleaned all the contacts with isopropyl diluted in water, that I use for lps.
I made really a difference.
Can you post a picture of the ultrasonic cleaner you have ? How much it costs?
Because the ultrasonic cleaning machines for lps cost maybe 2k and more. No way to invest in it.
I Caig deoxit’d everything (including plug contacts in wall socket and on plug socket at component end) during a lightning concern switch off and i swear it sounds better to me. More insight on a streamed album which sounded a bit muddy before.
