Will fine tune adjustments with protractor help with "brightness?"


Hello everyone-

I've had my TT setup now for 2 months. System looks like this:

Piega C10 Ltd speakers
McIntosh 402 amp
Technics SL1200GR TT
Lehmann Audio Black Cube SE II phono pre
MoFi Master tracker cart

My ears may be deceiving me, but I swear my vinyl cuts sound slightly brighter at the beginning of the album and soften a little as we near the middle. I set the cartridge by using the little white piece provided by Technics and it sounds great. I've been told by reliable sources that a good protractor, maybe even  Feickert Universal Protractor can help me get even more out of my carts. 

Would enjoy hearing your thoughts on this. Thanks! Brent

Update!

Mounted my second cart all by myself! It's the Vasari Gold Note. I'm sure it needs time to burn in. I never, ever, ever do things like this by myself and by Jorge I did it! I'm feelin proud.
@lewm  Yes, I will do that.

@avanti1960  Thanks for clarifying.

@knollbrent  The key is taking your time, no rushing, good lighting and a microscope.

On the Technics, if the new GR is using the same arm geometry as the old 1200, traditional Lofgren alignment would result in a much greater overhang, approximately 3.3 mm more, and Baerwald would result in about 2.8 mm more. In both cases the cartridge would have to be angled noticeably toward the spindle to align properly.

Stevenson alignment on the Technics with a 215 mm mounting distance would result in less than 1 mm more overhang as compared to the Technics alignment and the cartridge should sit almost square in the headshell. 
Dear @avanti1960 @ericsch @knollbrent : As other japanese tonearm manufacturers almost always exist some kind of trouble to know in precise way wich kind of alignment used because normally are out of standards.

The 1200 is a clear example where if we decide to make calculations below IEC standards the alignment numbers does not even what Technics states. Technics does not gave the precise/accurate/measured P"S distance that for the alignment calculations is a fixed parameter that we can’t change. I’m not an owner of a 1200 so I can’t measure it.

Now, if we change the calculations to the JIS standard then we have those 15mm ( 14.99 ) on overhang and 22.1° as offset angle. This is the nearest numbers using the diferent standard parameters. Obviously that any one can change those standard numbers to make his own calculations.

Now, Stevenson with JIS standard ( or IEC/DIN. ) has lower tracking distortions ONLY in the last 5mm inner grooves and higher tracking distortions in the other 90mm of recorded grooves ! !


Regards and enjoy the MUSIC NOT DISTORTIONS,
