Just the first paragraph.Yeah, I couldn’t make it out either. And I can’t sort out if he’s talking about a damping device like a trough or if he means a damped arm tube (another thing altogether) or if he’s talking about the mechanical resonance window.
I got the last paragraph. He is saying even if a tonearm and cartridge are set up correctly you still need a damping device.
@rauliruegas , again, use the google translator.
Go to Google,type ’convert Spanish to English’(https://www.google.com/search?source=hp&ei=kOdbX7HwLInbtQbhtpnYBw&q=convert+spanish+to+engli... )
Put your text in Spanish into the box; highlight the English result and paste it here.
When reading a post that you feel you need to respond to, do yourself another favor and drop the post into the Google translator, only this time using ’convert English to Spanish’. Then you can read it correctly.
As another tip, there is something called the ’Dunning Kruger Effect’. This is where a person that knows a little about something tends to think that they are a lot more expert at it than they really are. It tends to cause blind spots in a person’s perception of the world. In this case you might think you are pretty good at English; please use the Google translator.
