Why the sudden popularity of 12 inch arms

Dear Downunder: IMHO I think that looks like a misunderstood from your part.

In any of my posts I told that the 12" tonearm are not good tonearms or that are crappy ones, I don't know from where you have that on your mind!!!!!, this is like if I tell you that your CJ preamp is a crappy preamp!!!. Downunder till today I never bought/own/owned any " crappy tonearm ", now you are clear of them.

Maybe I have to add some explanation on why I'm using the 9" tonearms: after that its performance is a great one ( with no single advantage from the 12" ones. ) the overhang on all those tonearms that I own ( the short ones ) is exactly the same and this fact make me easy the interchange of cartridges between them and this single fact is of paramount and critical importance to achieve the best from any phono cartridge.

Regards and enjoy the music.

Raul, whilst we all appreciate the experiences and comparisons that you bring to this forum, I think that Zieman has a point.
Your claim that the old technology of arms is as good as, if not better than the new, is demonstrably false just as your beliefs that the older cartridges (both MM and MC)are legitimately comparable to the newer LOMCs.
In my experience, the greatest advances in analogue playback have occurred in just the last 10 years with arms, cartridges and turntables!
Your most 'modern' turntable appears to be the Acoustic Solid from Germany. I have heard their Mambo and I'm sorry to tell you that this is not comparable to the Raven AC, Continuum Caliburn or Criterion nor the Walker Procsenium or Rockport Sirius.
The arm I have discovered since mounting the Continuum Copperhead, is just as important as the table and the differences can be quite stunning.
Once again all your arms cannot bear comparison to the Copperhead, Cobra, Phantom, Triplanar et al.
For you to claim that you have heard all these tables and arms and believe your tables and arms are just as good, means ALL of us can happily make those SAME claims about all OUR equipment as well.
It doesn't unfortunately, make it so.
To compound the problems I have with you, all your arms appear to have readily interchangeable headshells which presumably have plug-in electrical contacts?
For decades, most reviewers and arm-designers have eschewed removable headshells because of the sonic degradation involved and extra electrical contact points.
The sum total of your 'less than SOTA' turntables with your dubious arms with removeable headshells, seems to me to indicate that the sound you are able to extract from the vinyl is decidedly second rate.
The differences you will still hear between cartridges, but the validity of your opinion is severely compromised by the real lack of nuance and detail that you are missing.
Now it is absolutely fine for you to be happy with your set-up and system.....but when you progress to making absolute decrees on the universal quality of arms and cartridges to readers who have little experience,it can be dangerous and misleading.

Raul, sorry my poetic license for the use of "crappy"

However You quoted " I change six long tonearms for the short ones because I can't find a real/true quality sound improvement in the long ones"

Therefore you must have the same tonearm's in 12 and 9 inch and as you have indicated the 12 inch versions offer no sound improvements over the 9 inch version.

Please tell us what six 12 inch arms in your opinion offer no performance upgrade to their 9 inch versions.

I am certainly interested and I am sure a lot of other people are too, so we don't potentially waste our money upgrading to the 12 inch versions :-)

cheers Shane

Downunder,

I was quoting you re the walker kills the Phantom. Or did u mean the air tangent??

Sorry I did not make myself clear, I was referring to Walker beating the Air Tanget as I had them at the same time. I also had the Versa Dynamics and the older Graham 2.2 mounted on a Basis Debut Gold MK 5.

What does the air tight bring to the sonic table that beats your Koetsu Jade's??

The Air Tight is faster, much lower distortion, higher resolution and detail, tracks better and images better.

Another benefit in my system is the output voltage. Koetsu Platinum is .2, Air Tight is .6. My phono (Aesthetix) is all tube, so this higher voltage (by default :^), lowers the noise floor, giving the first stage input tubes a lot more signal to work with.

Dear Shane: Ikeda, Fidelity Research, Moerch, Audiocraft, Micro seiki and SAEC. With the right ( matched ) cartridge all these tonearms ( long/short ) are really good!!!

Regards and enjoy the music.
Raul.
