As with the mm cartridge, if the capacity is too large, the bandwidth and dynamics are reduced. it shifts more into the midrange and bass. Some people like this sound because open highs can sound aggressive. Usually something is wrong in the chain. You often hear in forums that Silvercable is to blame, but that's not true, it just exposes weaknesses elsewhere.Even though I don't use high capacitance anything, I still wouldn't distinctly say it's dull or warm.
It is then quickly exchanged for copper cables and all is well again.
Only few people question it why?
