(in Progress. I will add more info here).
We recommend Zerodust.
Please avoid using liquids in particular alcohol based liquids for cleaning.
Any ZYX (even the Bloom) is among the quietest cartridges anywhere. This is largely due to the ZYX micro-ridge stylus, which is finer than any other I know of. When it encounters a scratch or other flaw it plays it cleanly and quickly, without blooming or exaggeratingt. Of course it does the same with fine musical details and HF’s too.
Keep that stylus clean!
