VTA setting for 'parabolic' and 'elliptical' styli

Hi,
please let's have some expert opinions based on experience regarding this subject.
One cart manual specifically recommends negative VTA (arm down from level at pivot) for parabolic styli, as compared to some elliptical styli prefering positive VTA (arm up from level at pivot), see Townshend IEE 500 manual:
http://downloads.nakedresource.com/ve_download_centre/index.php?townshend/elitetownshend_cartridges.pdf
as seen on Vinylengine: http://www.vinylengine.com/library/townshend/eei-500.shtml

To further confuse the issue, in a manual for the Garrott P77, also using a parabolic stylus (Micro Tracer), it states the complete opposite, moving the arm UP by 4-5mm for best VTA...! That's one hell of a lot positive VTA, close to imposible to even realise with mu SME-V. (The arm begins to bottom out on the lowered arm-lift)

Could anyone shed some light on these contradictions for us?

The 'EEI 500' does work best with negative VTA, and so does my A&R P77, also sporting a parabolic stylus.
In terms of ALL line-stylus type carts (all my MCs) it was ALWAY understood that UP from level gives more treble and DOWN less treble etc. etc. (..in VERY simple terms, as we know the whole spiel).

It needs to be mentioned, that the MM carts noted above **appeared** to need more arm UP to sound correct, according to my then current experience --- indeed they seem to work the other way around! Hm...

Well, Herr Tonarm :-)

so what's the solution?

Get a VTA-tower of some sort, or spend ~ 5min plus extra with every LP played to re-set VTA?
And then wear the hole mechanism with all this up/down, it was NOT actually designed for in the first place?

I share your goal for best possible play-back --- the enquiry is about where this 'best possible' starts & ends for the individual enthusiast, including money AND time spend.

Not every one driving a car requires a Bentley or a Bugatti, I think.

Pondering,
Axel

Well Axel,

its max. 1 minute we are talking - not 5 min plus - that is required to getting the VTA adapted to the specific LP laying on the platter.
That 1 minute is vital.
Seems as if each of us spends much more time online in forums lately than the total ad-d up time for VTA adjustment for many hundreds of LPs played.......

You see - there is simply no point in NOT doing this - for any reason.
If you not doing it, you are putting the performance level of your whole front-end to chance and risk.
And teh odds will be against you - by a huge margin.

Cheers,
D.

Hi,
so no compromise solutions on VTA, is where it's at.
I had it coming I guess, hm.
"Ask questions, get answers" :-)

I've already increased my stock of VTA shims by over 100% in between listening and blogging. And now I guess I better shut up.

Greetings,
Axel
