Tracking error distortion audibility

Raul,
you're the man! Couldn’t agree more with you.

Note: The Azimuth has to items to it: lateral and vertical Herr Tonearm explained...

Vertical is A OK with a cart like PW in an SME, it allows for some degree of tilting due to it's 3 point mounting plate (must have thought of SME here :-)

If the cantilever it too skew to the cart's body we are in BIG trouble with SME's non slotted design. BUT ONLY is since everyone asked for screw holes in the cart mounting plate!
This then has next to NO adjustment left to 'twist' the cart left or right. If the cart has just the good old lugs with the long bolts and nuts used at the bottom, there is enough play to come right usually, maybe not with the worst though.
It seems the price to pay for a more 'comfortable' cart adjustment...

This is actually was what I found out to be the source distortion. I got it pretty much fixed, but juuuust just with max. twisting to the left as so to align the CANTILEVER, never mind the cart body it mean NOTHING. Look at the cart body --- you can't even notice a difference.

Thank you for caring,
Axel

Dear friends: IMHO we have to see/take ( everyone ans specially the tonearm builders. ) the tonearm like a " tool " a very precise tool that ( between other important subjects ) can/must give the opportunity to have a near perfect cartridge ( like a whole. ) alignment through its " facilities/infraestructure " .

Some ( fortunately only one or two ) tonearm builders say that they don't compromise the tonearm " rigidity " ( or the like ) for some of that cartridge alignment " facilities ".
I respect their opinions but I disagree with because I think the " source " is the cartridge not the tonearm ( the tonearm is " only " a tool/medium, a very important and critical one no doubt about but the main " star " is the cartridge. ) and IMHO the main target has to be a " perfect " cartridge alignment and from here they and us can do anything they and us want it.

This is my approach: I don't like ( through my experiences ) trade-offs on cartridge alingnment due to tonearm limitations, I prefer a trade-off in the tonearm device, at the end of the day nothing is perfect and certainly not the cartridges ( that's why we need those tonearm facilities. ), but the " success " or not comes through which and where we all accept trade-offs: where a trade-off made/makes less harm.

Regards and enjoy the music.
Raul.

Raul,
well said! BUT in order to understand this position you take, it needs some intimate knowledge of the subject matter --- and unfortunately this takes time, and more importantly interest AND motivation to acquire it.

A lot of folks don't want to know the details of their car's differential gear, but simply use it.

So, that said, it might make a case for Linn and SME's non-variable approach.

I'm also not really sure if a very 'funky' adjust-all approach is the last answer to all this.

As with all things, learn as you go --- THEN make a more informed decision, on what is best for your needs AND preferences, or?

Thanks for your ever present words of wisdom, it always makes for good reading.

Dear Axel, as for your quote:

"""""A lot of folks don't want to know the details of their car's differential gear, but simply use it.

The reason why today we can just enter the car and drive without knowing the details and without having to adjust some things before starting the engine is, that in the past 100+ years a lot of well-educated engineers have put endless work into the complex topic "automotive car" and have solved all problems (and there were an endless number of problems in the early decades and still today cars are improving).

We are far from that state of development with analog front-end.
Far less time, far less high-trained manpower, far less money.

Till we can use analog front-end with the same ease as our cars, I will have a long white beard...... and I am not that old yet.

:-) Dertonarm,
Mine is not long, but white for sure, and SME's founder is dead by now.
It must have been at least their intention to move on with all this fiddly-dilly alignment stuff. I feel obliged to give them credit for it, even one can't agree with it all at times.

Incidentally, I just learned by John Carr himself, that Lyra got it right on target with the stylus-tip to mounting hole-distance 3/8" = 9.52 mm tolerance +/- 0.3 mm.

So, yet another step in the right direction.
Get a Lyra, get an SME, and stop worrying about your 'differential'-> alignment(s).
Jolly good show, I say!
Best,
Axel
