Glanz moving magnet cartridges

Dear Don, That is probably why the Dutch invented this saying: 'Protect me my Lord from my friends I can manage my enemy myself.'
Henry likes to tease me with Raul's influence but he forget to mention that I always prefered the (LO)MC's above the MM kind while the Mexican only recently changed his mind in this, uh, connection. Anyway I mostly agreed with his MM valuations and only with the Ortofon MC 2000 of the MC kind. While I can manage my enemy my cheap Jasmine phono-pre can manage Ortofon's output:0,05 mV. What a cart! Realy difficult to believe considering the price.
My conclusion: not the carts are important but our knowledge about them is.

Regards,

Dear Professor, I need to read your prose at least twice to understand by approximation what you are talking about. Your lirical productions are, alas, impentrable for a foreigner like me regardless how many times I would read those. When I invited you to this thread I hoped for your humorous and informative contributions. I now hope that Lew will join us because he was always willing to explain to me difficult American expressions (like 'prostitute variations', etc). Besides he is among many other things also interested in (Italian) cars so the right person to explain your strange parallels between cars and carts.
I hope you will be not surprised with this kind of welcome 'speach' from your friend from the Balkans?

Regards,

Greetings Professor,
As usual....an interesting contribution and a great Link. Thanks....
As the only damped tonearms I've owned have been uni-pivots (Hadcock, Grace, Graham)...I'm not sure how other types can be damped unless one resorts to the DIY outboard rigger in a bath of oil as shown in your Link?
But without derailing this Glanz Thread for Dgob.....perhaps we should begin another?

But as Nandric seems to be consumed by the madness of matching the FR-66s to MM cartridges......I have tested it with the Garrott P77/SAS using the Shure V15Type V Audio Obstacle Course Test record and confirm that the resonant frequency of this combination is 11 Hz. A nice figure.....

But the question of the resonant frequency of a tonearm/cartridge combination only arises IF and WHEN the stylus meets a warped record?
Without a warped record.....there is no significance to this calculation?

There are far more important factors involved in the mating of an arm/cartridge IMHO....

Regards, Halcro: Agreed, Henry, although I do believe you are teasing me! However there are other means of damping a tonearm. Fluid damping is effective when there is a mismatch of cartridge compliance and tonearm mass, evident in "scrubbing" of the stylus in the groove and sometimes of the entire TA. Woofer pumping may also occur. It also serves to dampen vibration. Filling the TA tube with the material of your choice, wrapping with heat shrink tubing, anodizing, or strategic placement of neoprene washers or Blue Tack are thought by some to also be effective means of dealing with vibrational feedback. Alternate materials such as wood or carbon fiber used in construction of the arm tube are other options.

Both of my Technics EPA arms incorporate a vibration absorbing mass in the counterweight (Technics has an impressive name for the mechanism, it escapes me at this moment) which is positioned magnetically. Compared to my several other TAs, I consider the EPA-250 well damped.

Damp or dump- Raul mentioned vibration in the tonearm, it would seem beneficial to either dampen these vibrations or provide a line transference path capable of dumping those disturbances elsewhere. Afraid I view our hobby as a veritable carnival of resonances, critically damping or redirecting those disturbances to a vibrational sink goes with the territory.

It might be remembered that resonances can be either constructive or destructive. I'd speculate that this, relative to the cartridge used, contributes or detracts from the synergistic qualities Dgob referred to in a previous post.

In the past I'd posted on vibration in an anchored beam. That a tonearm is pivoted at one end and only partially constrained by the stylus at the distal end adds complications, usually manifested as untreated border resonances, vibration induced ringing or overshoot due to lingering resonance. Given a day or so to reassemble data and references, I'll give a better answer. Should anyone else care to contribute, please do. It will, I'm afraid, take longer to sooth Nikola!

Peace,

Dear Henry, 'The Bavarian audiophiles (and the Japanese) know their onions'. I first thought about their 'onions' in the context of being alliance in both (I +II) wars. But I now think that the Germans think about FR-66 as their own... This is because Japanese are educated in mechanical engeneering in Germany even before the first one. So they are a kind of a spirutual father of the FR-66 as one among (many) other armours.
