Dr. Feickert Protractor

Dear @lewm : As you know I owned that 505 and my alignment was made it using Löfgren B and never detected any single listenable kind of distortion.
I owned or own too almost all japanese top tonearm designs and always made it the same: Löfgren B with out no single distortion issues.
Your hipothesis is only that a hiphotesis.

Now, no one attend to a music hall only to enjoy the last five minutes of the concert.

In the other side, the audiophiles that like classical music like because the whole compositor work . The beauty of this kind of MUSIC it's not only in some parts of it but at each single note.
We all know that some works by Beethoven or Wagner or some other are works that takes more than one LP side even as the Opera or Wagner takes more than 2 LP sides.

So, where are the Stevenson advantages for any one of us?, just does not exist. As I told you makes no sense or as people says in USA: just bs.

Some one sold you that " crazy " idea ( for say the least. ) and you bougth it but with no precise or clear foundation.

Regards and enjoy the MUSIC NOT DISTORTIONS,
R.

I am sorry to learn that your system is not accurate enough to allow you to perceive the obvious distortion that I heard when I set up the DV505 for Baerwald.

I am joking, of course. But why would you say such a silly thing? Any alignment geometry that gets you two null points on the playing surface of an LP is as valid as any other that does the same. It’s impossible to argue with you intelligently, because you do not read the responses; I did not say that Stevenson was superior to any other, just that it is not per se inferior to any others. You are certainly entitled to your opinions, but please do not dismiss my observations simply based on your own. Most likely we were using different cartridges. A high compliance cartridge, for example, might be more sensitive to the aberrant force vectors generated when you twist the cartridge with respect to the long axis of the headshell (and to the single possible plane of the arc of the vertical bearing of the DV tonearms). No one else gives a damn about this discussion, so let’s bag it.

Dear @lewm : """  Any alignment geometry that gets you two null points on the playing surface of an LP is as valid as any other that does the same. """

Valid? yes because is an alignment. Usefully is the real question. Stevenson is useless per sé and it's not only an opinion. Please read my posts about.

yes, no one cares about.

For me it does not make sense sacrifice 20 minutes of the recorded LP surface in favor of the last 5 minutes especially because over those 20 minutes the distortion levels goes really higher against Löfgren A or B.

The answer is 45rpm 7’inch vinyl records, those records are small jukebox format, there are ONLY about 3 minutes of musical information on each side and the best alignment to reproduce this information is Stevenson alignment. Some of the rare singles released on 7’inch vinyl (aka 45s in collectors world) has never been releaeed on LPs, which make them unique and highly collectible. There are millions of records released in the USA on idependent labels ONLY in 7’inch (45rpm) format in the 50s, 60s and 80s. Even if the LP with the same track exist, the single (45 rpm / 7’inch) most likely will be a different take and different version, sometimes much better than LP version. Those signles made for radiostations, for dj use and for jukeboxes. But i will repead again that most of the 45s has never been released (originally) in any other format such as LPs or 10’inch for example. This phemomena is well know for Jazz, Soul, Latin, Reggae music lovers and collectors. Stevenson alignment is the best for 45s (7’inch records)

I posted this on another recent Feickert thread.
I've used a Fiekert tool over the years on several tables to great success. I just bought a new alignment "block" for $50 that is another great tool when verifying cartridge alignments.

I was off less than 1/32" but once adjusted based on this block things snapped into place.
