What LPs do you use for VTA adjustment

Dear friend: The best way to set up the VTA is: trust in your ears and experience in live music, take 3-4 records that you know very well and set the VTA where you have the better FOCUS ( I agree in all what already told you Dogdeacon ).
Best regards.

Dear Samir: Here it is another way to adjust VTA/SRA:
invert the polarity in one channel, put a mono record, set the preamp in mono and adjust the VTA/SRA where you hear least sound.
The VTA/SRA is a critical parameter, but don't be madness and obsessive with it.You, like me, want to enjoy music instead of adjusting equipement, so always we have to take a compromise position. I recomended that you use an average thickness record or 3 to 4 different thickneses/labels of records and finding the best compromise. Then : turn on your audio system and enjoy listening to the music.
BTW and only for information: The industry standard for cutting head VTA is 20 degrees, each cartridge is designed to function around this angle when the tonearm is parallel to the record, so you have to start with your tonearm parallel to your records, this position is very very close to the " ideal ".
There are many issues in the VTA/SRA, but what you want is to know how adjust it and I think that now you already knew it.
Best wishes and always enjoy the music.

Dear Doug: As you know I'm a newcomer to this forum. In this time my perception is that you always give an answer " because you have to give an answer and argue about ". I explain this issue: you told us that " only takes 30 seconds for do a change an do a correct adjust to the VTA ", I wonder how in this 30 seconds anybody can do it. I gave to Samir two ways to adjust the VTA/SRA: by ear and " invert the polarity ...", these is the issue for Samir and I think that these elements can help him to do it and I urge him to enjoy the music and your answer is " that this adjust has to do in each record . This is what you are doing." I think that Samir, before doing this, have severals ways to improve the quality of him sound reproduction, but this is other history. Another exmaple: the stepup transformer issue (remember ? ): you put some answers defending the use of the stepup transformer because you use it, you never said " OK. I will try a preamp with a built in high gain phono stage and we will see what happen ". I think that the only way to learn ( all of us ) is having an " open mind ". I respet your ideas but I think that you need to change your attitude. BTW, in one of your answer to me you write: " I would never quarrel with your experiences ( wich exeed mine )...", I refer to this because like in the step up transformer I already live the experience, too, with the adjust in VTA/SRA, and like always I want that the people enjoy the music in an easy manner with top quality. At one time I was an audophile, like you, now I'm a music lover ( I always been a music lover ) at my home. I already pass for everything trying to find the best music reproduction. Now, I'm worried about to have the time to enjoy the music.
BTW, like Samir, you have severals paths for to have a better sound reproduction at your home, invest your time on it and share with all us your findings. That is what I'm trying to do.
God luck.

Hi 4yanx: I really appreciate your answer. Thank's God, Doug don't match my experience, if this it happen then we don't have anything to talk about it.
My point is that, till now, Doug never open the window " to see what happen out side his home ". This is what I can see on my forum time. The stepup transformer was a transparent case on it, he write one and again defending what he has at home never told anything different on his position. He close the door. That's the point.
Anyway, TKS again for your answer and remember always enjoy the music.
Raul.

Doug: I think that you don't understand my point of view,that I already explain to you and to our friend 4yanx,
the issue is not if you are correcting what I say ( there is no problem with it. You have the rights for doing that. ) the issue is that ( my impression ) you are a close door. That's it.
Like our friend 4yanx ( btw, wich is your name ) told us, about the stepup transformer, " all things equal ....", why don't try about my absolute statement and " we will see what happen ".
Regards.
Raul.
