Time to choose: Baerwald, Lofgren, Stevenson ?


I’ve managed Dr.Feickert Analog Protractor for a decent price (build quality is superb, such a great tool).

Time to play with Baerwald, Lofgren, Stevenson alignments on my Luxman PD444.
Need advice from experienced used of the following arms:
Lustre GST 801
Victor UA-7045
Luxman TA-1
Reed 3P "12
Schick "12

Baerwald, Lofgren, Stevenson ? What do you like the most for these arms?
Manufacturers recommend Baerwald mostly. 

Dedicated "7 inch vinyl playback deserve Stevenson alternative, maybe?
Since it's a smaller format than normal "12 or "10 inch vinyl, it's like playin the last track's according to position of grooves on '7 inch (45 rpm) singles. RCA invented this format, i wonder which alignment did they used for radio broadcast studios.   

Thanks

Well solving a problem and adding to a problem are different ,say,

approaches of the problems. We , I think, solved the problem stated

by chakster. We even reduced the problem to two choices by

considering Lofgren/Bearwald as the same solution. For those

who own many 7'' records Stevenson for others Bearwald.

The problem with the glued styli in exotic cantilevers can be

solved with aluminum (alloy) cantilevers which, according to

Carr (his post in the MM thread) have as advantage that the

stylus can be pressure fitted. I own 3 FR-7 kinds, Miyabi standard,

Magic Diamond and Anchor (Dertonarm) all with aluminum cantilever.

 Those are among my best MC carts. So to regard aluminum as

some kind of inferiour material is problematic.

The manufacturers as well as repair services get the cantilever/

stylus combo's from their suppliers. Those are mostly used

by the so called ''retipps''. Gluing a new stylus in the original

cantilever seems to be much more difficult than gluing the

combo in the ''joint pipe'' on which also the coils and suspension

are fastened. BTW the joint pipe is usually an aluminum tube.

The manufacturers as well as the retippers are

assumed to check the styli as delivered by their providers.

We can't complain by styli/cantilever producers if something

is  wrong with either.


Dear @cousinbillyl :  """  Stop obsessing, you can't get it perfect, at least not for every album. """

Agree, we can't get it perfect. I was at the Doug place and I know that he really is " obssesed " with each LP and hee does " easy " but is him.

All of us have our each personal whole test/set-up process. I have mine that I try to " perfect " over the years. My take could sound easy: through my own process I have 9-10 tracks that are my references other than live music and I make the /tonearm/cartridge set up with " obssesion " to pass those 9-10 tracks and when passed then I'm " there "  but I'm not looking for a change with different LPs.
At the end what I love is to listen and enjoy MUSIC.

What's my main target is that the whole set up been made it with " absolute accuracy ", in this I'm extremely obssesed: ACCURACY.

Regards and enjoy the music,
R.
Btw, in that test overall process I have too a " fast track " alternative that I use with all cartridges I'm listening for the first time and if through it the cartridge performance is a promising one then I follow with the whole process.

Regards and enjoy the music,
R.

A discussion from Fremer (w/ Wally M in the background) that shows choosing an alignment is partly a function of which position on the record yields more and less distortion for your alignment choice..  



 
Hi Lew,

I get that Stevenson has a significantly higher offset angle difference from (for example) Baerwaald than Baerwald does to Loefgren.  Re-reading my earlier post, I didn't make that clear.

I'll file this away for future experimentation, but know that my preference for Baerwaald over Stevenson is such that the effect you've observed would have to be significant to drive me to revert to Stevenson on such an arm.

Is it possible? Sure, and I'm always ready for a surprise.

Cheers,
