Inner tracks vs outer tracks

It’s not that bass is more pronounced on the outer grooves versus the inner grooves, it’s that  in the outer grooves the stylus is moving with greater velocity. this allows for a wider frequency response, both bass and treble can be more extended, and better sound quality in all ways, compared to the situation in the inner grooves, where the stylus velocity is reduced due to the reduced circumference of the LP at the inner grooves. As someone else aptly mentioned, it’s analogous to using tape to reproduce sound: high speed wide track tape is sonically superior to low speed narrow track tape for similar reasons related to the physics. To put it another way, it’s the law.

Good point!

Of course low frequency noise and distortion with outer grooves also tends to be typically most noticeable from record warp and other common defects in record structure and that is where a better tracking rig will clearly shine the most over a lesser one, ie where the roller coaster ride is the most extreme.

Double whammy there. Record rotation velocity is highest and warps also tend to be most pronounced with the outer grooves.

I don't worry about "inner groove distortion," as even with my simple old Linn table it's a "meh" issue...but if it is an issue the simple solution is to just listen to the first couple of tracks...problem solved.

Dear @thuchan  : It's obvious that you really support the unidin alignment that's " the best " not only for you but for several other low knowledge level audiophiles. Now you as many other gentlemans bougth the unidin protractor that comes with the Löfgren A/Baerwald Löfgren B, Stevenson and unidin with IEC and DIN standards ( why no JIS?. ) and paid for when  the " best/one " is unidin. Make sense to you pay for something/alignments that are  way "  inferior " to the " best "? and I know that people do not paid 200.00 but a lot lot more money: why more money?

Because as @millercarbon said:   all is about MONEY nothing more. Takes money from the people alignment very low knowledge levels. Nothing wrong with that because business is business and nothing comes by " free ".

Maybe @lewm  has a different opinion on that protractor alignments use.


Btw, the information in these links could be useful for you and maybe other protractor owners or to any audiophile:

At the end: it's really a better alignment unidin than the Löfgren ? , certainly not only different and with disadvantages.
