Raul, you're quite long winded and you bring a novel aspect to technical matters. Thought you might like to know, on another forum you're referred to as the 32 bit Bandito. Due to the length and number of your posts, I think Kraken might be more appropriate.
To address your last post, did J. Carr say that all metal arms must be damped? I doubt it, but it doesn't matter. You use that as justification for:
*IMHO no one can " to suck life out of the sound or smear it "" by damping a tonearm. You can't overdamp a tonearm.*
With all your ear training I'm surprised you can't hear the affect of over-damping a tonearm. One can MEASURE a negative affect on transient response by over-damping. It also tends to kill the natural sustain of acoustic instruments. I agree with Dover, arms are easily over-damped. If it was Dgarretson who said that about vacuum hold down, I tend to agree with him. It's easy to suck the life out of the music by over-damping.
I think you might be surprised by the number of people who add fluid damping to their arms. KAB sells a trough and paddle device that is popular, and it's very easy to DIY.
Too many words Mr. Kraken, too many words.
Sincerely,
