Why the sudden popularity of 12 inch arms

I think the discussions and debate's that are ongoing is great.

My original point of the post was really to see if any folks had changed from a 9 inch arm to a 12 inch arm and what were the results in your system.

Clearly Zieman has seen positive results in changing to a 12 inch arm and that mirror's RG's review in hifi+.

Me I have had two 12 inch arms for a few years now so I can appreciate the better tracking at the end of a record compared to my 9inch naim ARO arm on my LP12.

If I understood te RG article correctly, he concludes that a relatively inexpensive linear tracking arm outperforms all the 12 inch designs.

Dear Downunder: Well, it seems that the only one that changed from 12" to 9" was me and let me tell you that I change six long tonearms for the short ones because I can't find a real/true quality sound improvement in the long ones, maybe my music/sound appreciation and music/sound priorities are totally different from yours, that's all.

IMHO this kind of performance/behavior is almost totally dependent on the tonearm/cartridge combination and not because one tonearm is longer than the other one. Here we have to remember that the Aro is a unipivot design that are not the best trackers at inner record tracks. For you can get to your conclusion you need a 9" Aro against a 12" Aro and even here the result is dependent with the cartridge match with either tonearm model.
I had that experience with the Audiocraft AC-3300/4400 and the Morch DP-6 where the only variable were the arm wands size and there is no differences that I can say: " it is because the arm wand size ".

As I already posted in a well tonearm design and well tonearm execution ( build ) the arm wand size can't make " the differences " for the better in a 12" against a 9-10" one, there are other factors that are more important and critical for the quality sound performance and I'm not saying that the size is not important it is but not at the level you or other reports about but because of its disadvantages against it " theoretical " advantage.

It is the same for ( IMHO ) the false assumption about the " perfect/mimic " cero tracking error advantage of the linear tracking tonearms, there are a lot of other factors that have a huge influence in the whole tonearm performance. Of course that some people like the linear tracking or long pivot tonearms but that does not means that are better ones and for the reviewers that support those tonearms designs we have to think/take in count that they have/must support to their advertisers and to the today products: specially the " new kid in the block ", very difficult to really trust on them: they are part of the audio business, I can and understand that.

IMHO you can/could obtain almost perfect/stellar/excelent quality sound reproduction from either tonearm design: long or short one, obviously with the right cartridge in either tonearm design and I can tell you more: either of these ( well cartridge matched ) pivoted tonearms outperforms ( overall ) a well matched linear tracking one.

Regards and enjoy the music.

Much earlier in this thread, I said the same thing Raul just stated -- namely that the tracking error reduction from a 9 to a 12 inch arm will be sonically insignificant compared to other factors. I think it's also important to remember that the original reason for having 12" arms was for playing broadcast 'transcriptions' which if I remember correctly were 16" in diameter -- it had nothing to do with reducing tracking error.

Raul, Even after Downunder explains HIS question to you SLOWLY, why do you refuse to stay on topic? Do you still prefer drum brakes and carburetors as well? Ignoring, or not having a basic grasp of the laws of physics won't make them go away. Perhaps having a garage sale and purchasing something from THIS CENTURY might change your mind. If you have some romantic attachment to obsolete/vintage gear, that is cool. And your perogative. I have some myself, I keep it to remind myself of times when I did not know any better and couldn't afford anything better. You may have your own reasons for clinging to the past. You do however, look really ridiculous trying to convince the OP that it is HE and not YOU who does not understand HIS(!) question, or any of the answers. There are many elementary books and classes to help you with the basic science that is being discussed here. Keeping abreast of current materials research and manufacturing tecniques may prove more difficult. There is however, no voodoo or magic involved in answering the OP. Please read, SLOWLY, and perhaps several times, the article by MR. SME, a gentleman who has forgotten more than you or I will EVER know about vinyl playback that discusses material relevant to the focus of this forum question. This may take you several days to digest, if you have trouble with any of the big words, I'm sure there are many members willing to help you. Myself included. Good reading! Z.
