Geometry for pivot tonearms - calculation errors??

Howdy,
here me meet again.
Just been thinking about Dear Lewm's input, which makes me think to start a thread for the 'poor' V owners i.e. which carts are a GOOD/BEST fit?

I guess we'd mostly look for MCs despite Raul's most extensive experience in MMs.

The cart stylus to mounting hole distance IEC-standard? is in any case to be 9.5 mm for the V arm.
DerTonarm will want to know it a bit more down to the 100th mm so we'll call it 9.52 mm (actually 5/8"). Now for me that begs the question why ICE would have settled for inches?! The mounting hole distance of 1/2" is also not quite metric, now is it?

What do you think? There'd be some folk to give some best fit input?
I use a Windfeld as you know --- and I would not add that to the list of BEST FIT! Amen. Sound great, but not BEST FIT in the alignmnet sense, methinks.

What else can a V owner do? You have mentioned all's fixed, can't even mess around with different flavours A, B, Stevenson...
It's vanilla SME, or go buy some other tone-arm, right?

Best greetings,
Axel

Dear Axel: My experience on cartridges are that: experiences on cartridges, MC or MM. I don't now why I give the impresion that I'm or have a MM bias, I'm not.
I have several MC experiences with vintage and today cartridges ( I own and owned ) and like the MM ones the MC has its own advantages and dis-advantages, same with the MM.

+++++ " With the "right" cartridge, it is a VERY serious tonearm... " +++++

absolutely yes.

Btw, the non-perfect world on the cartridge building is more " delicate " because this audio item is not a " mass production " one but almost made each one by hand where we even find " differences " between cartridges on the same model. So what the " poor " V owners have to do is " wait " to be lucky with the cartridge we have. Of course that are some " things " that we can do but always this " things " are add-ons that ( one way or the other ) could compromise the performance.

Dertonarm, I have too some interesting subjects on the LP " standards ", we keep in touch very soon.

Regards and enjoy the music.
Raul.

Raul,
you are one of a dieing breed that STILL knows about MMs! That does in way mean to imply that you ONLY know about that.
But how many folks have gone through a truck load of that MM stuff? Nobody I'll ever know I'm sure, so please see it as a compliment and NOT as a limitation.
Bless you,
Axel
PS: so please give me some idea about the Shure V15 on a SME V, now how about that?!

Dear Axel: I mounted my 97Xe ( a small brother of the V15 ) in the IV and works fine so I don't see any trouble with your combination.

I don't like to speak about devices that already own a person but I can't stay " quiet " . This next thoughts/experiences are in the animus to help about:

I owned the V15MR that I try in different tonearms/headshells and with different load impedance values and in my system I never achieve " stellar " or near it quality performance even the 97Xe like me more and that's why I still have it.

If you or any other person wants to " introduce " in the MM high-end " stage " the V15 IMHO is not the right answer if we want to compare against a top LOMC like the one you own.
.
My advise is to go for one of the next cartridges ( either ): Nagaoka MP-50 or better yet the MP-50 Super, Ortofon M20FL Super, Audio technica ATML180 OCC and/or Signet TK 10MLII.

Anyone of you could be " shocked " with the quality performance on these MM cartridges. Can/could beat a top LOMC ones?, I know the answer but the best judge are you.

Those cartridges are only the tip of the MM iceberg.

Normaly these MM cartridges perform better with a load impedance over 70K and total capacitance below 200pf and are so " inexpensive " that we can own dozens.

No, I'm not saying or implying in anyway that instead of our beloved LOMC ones: no, the MM is another very good " flavored " source.

Regards and enjoy the music.
Raul.

Dear Axel, dear Raul, - I am very familiar with teh AT-180 ML and I want to support Raul's recommendation of thsi particular cartridge. It is outstanding - a very serious contender for most of the $1k to $3k of todays high-flight MCs.
It should work very good in the SME V as should its bigger brothers from AT - why?
Because all AT-cartridges do very precisely hold on to the standards (as do all Ortofons...)in stylus to mounting hole distance and therefor will support the fixed alignment of the SME V.

But - can we discuss the SME V in particular in an individual thread??

Hey Axel - how about starting a thread about the special situation of the SME V in terms of its geometry and design?

I am sure this will get much attention as the SME V is widely owned and I will gladly support it.
