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

Dear @hdm :  You are rigth. The incredible issue is that several audiophiles work with Stevenson A alignment when makes no sense to use it for any one.

Btw and only to add that Baerwald is who took the credit for the alignment that has his name when in reality was Löfgren who has two alignment solutions: Löfgren A and B where A solution is the one that time latter than Löfgren achieved to that same A solution. 
So the true " property "/autor  was Löfgren with those A and B solutions.

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 ! !

Dear @knollbrent: Yes, you need a good protractor like the one you name it.

The main reason for that is not onlt to have an accurate alignment but to stay away from Stevenson A alignment type that's what you have now. I totally agree with @lewm  and @invictus005 in that regards.

After you did it and listening to it maybe could be a good move to use a different headshell than the stock one.
