Time to choose: Baerwald, Lofgren, Stevenson ?

@chakster : Again, """  Time to play with Baerwald, Lofgren, Stevenson alignments... """"

Do you already did it? what happens? whcich one do you prefer?. You are the one that in your system and according your music/sound priorities the best judge.

Accuracy means that any alignment you choose or like by your experiences " playing it " must be accurate on set up.

I can't understand why you ask for other people experiences on alignments when all depends on that accuracy level, system, kind of LP and personal priorities. All alignments in a pivoted tonearm designs has tracking error and some distortion levels. Differences is where in the surface LP grooves happens those different levels of distortions and that's all.

Alignments is not a rocket science very dificult to understand.

regards and enjoy the music,

Hi Raul, i’m gonna experiment with different alignment and different cartridges since the reconstruction of my new room is finished, finally. All set-up is ready to use and i’m looking forward to test everything.

Now about alignment for everybody:

Baerwald and Lofgren made their fundamental publications in the first half of 20th century. Later in the early 60s Stevenson (another mathematician) has calculated a new set of parameters taking into account that on records with classical music very often crescendos occur towards the innermost grooves! That make sence.

The key word for Stevenson is "crescendo" which is a passage played with a gradual increase in volume or intensity (in classical music). According to Stevenson's alignment method a new set of parameters taking into account that on records with classical music very often crescendos occur towards the innermost grooves. 

It's about arrangment of the classical music and where is the most complicated grooves located on the record surface (beggining, middle or toward the end on the record). It can be true if we are listening to a long (17 min for example) classical music track on 12'inch or 10'inch (or even a short 3 min track on 7'inch record). 

A crescendo is a way for composers to indicate that a passage of music should gradually increase in loudness over time (opposite of a decrease in volume which is described as a 'decrescendo'). It is also used in non-musical context to describe any situation in which volume is increasing.

BTW the most complicated grooves with cannon shots on Telarc 1812 Overture located in the end of the LP.
