Where should the vocal image be?

But, as Eric stated, depends on the recording. 

i mentioned this in the beginning but i see Eric gets the credit

1) depends on the type and model of speakers

2) do not toe in certain speakers, especially Dali's

3) depends on the recordings, too many variables to even begin to discuss regarding this.

Credit on Audiogon really doesn't mean anything, people will still misspell your name even when it is right in front of them. 😂

LOL, sorry Erik

I have used the formulas presented in this link and slight variations or tweaks to enhance imaging and sound stage. The addition of room treatments have helped also.

Good jumping off spot and you will get to your goal on vocal imaging.
