"S" shaped tonearm ?

Being that my daughter never stops reminding me how old I am getting,I'll have to state that OLD is ALWAYS better!! -:)

I don't have nearly the technical knowledge of the vast majority posting here.Yet,I, truly, try to be as open minded as I can,especially on the subject of NOT rationalizing,to suit something I have or like.I still occassionally buckle in,and go for something that has demonstrated superiority,on enough occassions.
If I can add a "little" input on the "old" vs "new" subject.Basically from the fortunate ability to hear a load of quality systems......I had always been impressed with some of the latest really cool "stuff" the industry had to offer.Yet I have been "amazed too many times",with the abilities of some of the more experienced hobbyists,and their own particular approach to component choices/system voicing.New isn't consistently better,and old can still "sound" old!
The business of "oldness/no good-anymoreness" is absolutely silly.I have heard set-ups utilizing much equipment over two decades old,that are ABSOLUTELY competitive with todays best!The owner/hobbyist/thinking tweaker can have a HUGE imact on what he wants to accomplish,with a system.I believe many folks don't really know how they want a givin system to "sound",and simply "go" with each subtle improvement they hear.The system takes what ever form it desires,based on the changes.I have a few friends who go this way.They still sound fine though.....BUT....my "best set-up" friends actually KNOW "how" they want their music to "be presented" to them,from their music systems.To me,they have some of the finest sounding "music" systems I am fortunate to hear.On a regular basis!!AND there is a consistent "consistency" to these set-ups.Yet they have been involved with the hobby a LONG time,and have stopped being influenced by anything,other than their OWN tastes,a long time ago.
BTW:The best NOS tubes sure don't suck!!They are surely old though!!
Of course if there is a design benefit from something,and I do realize the inherent limitations of an "S" shaped arm(I think),then it will enhance the total "system" approach.
Alot of newer products are wonderful,and very desireable,and we all have new stuff somewhere in our systems,but the "GUY" who can rise above the non stop market influences,and "almost always" over reviewed products,who has good ears/experience/sensibilities/desire,will nine out of ten times have the better sounding set-up.New vs Old is absolutely meaningless to them.
At least that has been my experience,and only based on my own tastes.
I hope some of this makes sense.

Dare I say it?....I think the earlier post by Audiofeil makes the most sense.The scientific theory,and overall arguement just seem to make the most sense to me.
Based on personal usage,I could probably make a case for a "straight" arm linear tracker being the ONLY way to go,as the ones I have heard were clearly superior to any arms in my experience.This is not the topic here,but it's a fun thought,as the "pondering" aspect of this thread hs brought out alot of conjecture.
Best to all.

Raulwith all due respect I think you did not truly understand my point.
Best

BTW Raul,I was being a bit sarcastic.Just in case you misinterpreted me,which seems to be the case.
As to the subject of you mentioning,why should I "talk with people without hnow how on the subject",I am anxiously awaiting your arm design.
Best regards
