Is extremely accurate "VTA" adjustment necessary?

Dear Doug: ".....why these attacks are with out basis...".
From the first time that I post in this forum you was attaking me, last time in the Shroeder tonearm thread. You don't like that I don't agree with you in every subject, sorry I can't do that, but when I disagree with you or with any people in this forum I never attack to anyone: I only expose facts about the subject and always trying to help. I know that many people don't agree with my points of view, but I don't attack them for that, as a fact I always learn from their points of view.
I'm not against you and I have not any bad fellings about.
Many times we think that we already learn everything in the music home reproduction and we close the door. Many of my points of view are very differents from the people point of view in this forum and many of those peoples are really close to learn/change/test/check/understand and that's why all of them ( including you ) have so many trouble with my posts.
If you or anyone don't accept differents facts on differents subjects from yours: it's ok for me and bad for you.
I think that in this kind of forum all of us wins one way or another: it is not who are right but how can help to all of us.
There are many ways to growing up in the knowledge in home audio. Doug for your last choices you choose one of the hardest roads for growing up, I explain this ( it is not nothing against you,please ):
as I already speak about and the time confirm it, you do a mistake when you choose the Origin live tonearm against the Moerch one: and that desicion do that you have to pay for two tonearms ( OL and Triplanar ) instead of only one, the Moerch.
Like five months ago you not only be happy with the Shelter 901, I read your posts about it and I can say you was in heaven with it. In that time I disagree with you and I post that the 901 was a hi-fi cartridge and that the 90X ( as you know I own both ) was the " lonely star ". Five months latter you find that the 901 is a hi-fi cartridge and you do another double mistake: buy the ZYX cartridge, why a double mistake?: you already like the Shelter sound and the 90X is an stellar performer, why don't change the 901 for the 90X?, instead you choose a cartridge that in its actual generation it is not in the same league that any other top highend cartridges, maybe " other peoples " take this desicion for you: Salvatore, reviews and all your audio friends. Yes, I already hear three differents models in my system ( one of them I buy it and two months latter I sold ). I think that this manufacturer is right on the road and that their next generation of cartridges will be on the very top.
I know that this is your money and that you can spend where you want, but there are better ways to spend our money: the audio is a expensive love for the music, don't do it very, very, very expensive.
As I already told you: no bad fellings.
Regards and enjoy the music.
Raul.

Raoul, what are you doing? I can see *you* need software: a complete DVD collection of "El Chapulín Colorado".

¡Cállate cállate que me desesperas!

Ooops, that's "El Chavo del Ocho." Same comedian, what the hell...

Raul, if you are buying all of these cartridges new, then "testing" them, only to sell them in a month or two, you are wasting more money that Doug ever dreamed of wasting! Of course, as you say, people are free to waste their money at their own whim.

You have indicated that you have tested quite a wide variety of tonearms and cartridges. Please provide us with your first-choice combo at, say, three different price levels. Should be easy for you after all of this testing and would give us your "reference points". Thanks

As a "newbie" (about one year) to analog, I cannot debate the views expressed here with any authority but I am interested in continuing to learn and improve my sound. My approach to setting VTA and azimuth has been to use a little bubble level with double stick tape, centered right over the arm pivot point to level the arm (with the needle dropped into the groove). I can very precisely adjust the VTA and azimuth of my armbord on the fly with this approach. One eighth of a turn in the allen bolts of the arm board is easy to detect with the level. Also, the record clamp causes the record to be pitched down towards the edge and this angle can be matched in the cartridge.
This is probably a "crude" adjustment by above standards but I am pleased with the sound and it seems that most used records have warp, even with a record clamp, that is 10 times the tollerances mentioned. Like the original poster, I am wondering if I am missing a great deal by not paying more attention to this? I would suggest to him that flatter records ( perhaps by using a rim weight) would need to be the first priority before more criticality in VTA adjustment.

Raul,
Thank you for the kind sentiments. I understand you're trying to share all that you've learned. I'd like to discuss your points/questions, but not here please. Restock started this thread to discuss VTA theory. Out of courtesy we should stick to his topic.

There are aspects to our OL/Moerch and Airy/90X decisions that you don't know about, simply because I've never posted them. I'd be happy to explain if you wish.

If you truly think my little audio history is of general interest, please start a new thread and repeat the above post. That way only the terminally bored will have to read about it! ;-) If you'd rather just have me email a response then let me know and I'll do that.
