Graham Phantom vs. Phantom II

Good question. You are on the right track...when I would have the chance for a custom made cartridge, I would prefer AlNiCo's. But to be honest, these alone are not the secret, there are outstanding cartridges (Miyabi for example) which sound very life-like and some don't (XV-1s) or you go to one of these FR-cartridges, they have a kind of Pysical Force which is rare to get. Even today. But then you need a different Arm and a real high gain Phono section.
But to go back, the Helikon is right, when you have the chance to get one used, try it. There is worse out there.

Hi all,

Does anyone know the effective mass of the new Phantom II?

Thanks.

Jaspert,

The armwand of the Phantom I is 1 gm heavier than the Phantom II. That doesn't answer your question but the effective mass of any arm is a function of the distance of the couterweight to the pivot and possibly in the Phantom's case the amount of damping fluid would change things. I would assume for a fair approximation about 11 gms.

As for ALNICO - even if there are "better" (read: stronger, smaller (=concentrated) and more homogenous field emitting) magnets on hand today, the "oldschool" Alnico as well as the rare earth samarium-cobalts magnets in cartridges old and new often (not always....) do have a sense of "rightness" and "live-likeness" going with them. I suppose however that this is a kind of side-effect of and interaction with human hearing similar to the 2nd order harmonic distortion which is one of the technical basis of the seductive sound some SET-amplifiers can produce in the ears and minds of some many listeners.
On the large scale however I think one single parameter is paramount in the design of a true outstanding cartridge.
The clear concept in the mind of its designer and (most important..) his individual taste in sound and the ability to bring this particular taste into sonic output.
Isamu Ikeda and Takeda certainly didn't design outstanding cartridges because they are technically better in this than other skilled designers.
Or because they used mysterious materials others didn't find out about.
Maybe they just had a very attractive and precise vision about the sound they wanted.
And didn't settle for less than a product which did exactly what they had in mind.

The distance of the counter weight from the pivot does NOT determine the effective mass of a tonearm.
The damping fluid is located circular around the pivot and thus the amount do have ZERO effect on the moving mass of the tonearm.
The effective moving mass of the Phantom 2 is between 15 and 17 grams I would estimate. This is the effective moving mass sans the cartridge. So the effective total mass is always and in any tonearm depending on the added cartridge body weight and the distance this added mass (the cartridge body) has from the pivot. Thats why similar designed tonearms (DaVinci in 10" and 12" version and - oldskool ... - FR-64s/FR-66s) do have different (and the "longer" tonearm of course always more) moving mass despite almost identical design and material.
It is true however that you should always try to get the counterweight as close as possible to the bearing.
The reasons are obvious.
