Discuss The Viv Lab Rigid Arm

I am trying to do my due diligence about this arm. I am just having a hard time getting my head around this idea of zero overhang and no offset. Does this arm really work the way it is reported to do?



The issue of zeniyh is almost bs because we all know that if exist something imperfect in the whole anolog subject is exactly ANALOG and what surrounded it.

How can you say the above and then go on about TAE of the rigid float arm???  As Lew pointed out the tolerance specification from Orbray and Fgyger is ±5° and just because you choose to ignore it doesn't mean it is not a huge problem.


Lew asked you if you paid attention to Zenith and you assured him you set the SRA with the nicest tools on the planet without answering his question about the zenith accuracy of your carts.   You could send them to @wallytools and have JR take a look at it for you.


There seems there’s much for me to learn with cartridge behavior regarding the hierarchy of TAE: zenith, over/under-hang geometry and anti-skate - including potentials with different profile styli.

Or, instead of concentrating on stylus tracking angle error, maybe a little thought into motor stability theory is in order?

In my way of thinking, there’s something seriously going on with lateral movement or stability that needs to be addressed.

Validity lies in the sonic experience which no doubt is extremely positive by every firsthand account.

As typically understood, correlation of numerical data does not always explain what sounds good.

Neon, Based on the post by J Carr in which he discussed various cantilever materials and also expressed the opinion that in retipping or restoring a cartridge, one might be best off sticking to the original chosen cantilever material, on the premise that the cartridge was designed and voiced with that material, I would choose to stick with aluminum if replacing the cantilever on an MC2000.  On the same grounds, better yet would be to re-tip the original aluminum cantilever.  Now I do respect Raul's opinions, and he did say that he likes the boron cantilever on his MC2000, or what once was his MC2000.  But we also know what Raul and Mijo think about the phrase "I like it" when other people use it.

@lewm the issue is there is not a tapered aluminum cantilever available to replace a damaged OEM one. Not through any cartridge builder that I am aware of. I wondered if the one fitted to an Ortofon Cadenza Bronze could be a possibility, but you cannot source one. 

When this first occurred I didn't touch an album for 4 or 5 months. I was really quite upset with myself. Only after I was able to contact @nandric and buy his MC2000 was all right in the world again. Then I had a reason to consider a repair of the first cartridge. This way I had an OEM version to appreciate, and still have an alternative to use for casual listening. Now if I could have found a suitable replacement I would use it in a heartbeat. But I do not know of one. 

@mijostyn     You mention the unnecessary obsession with VTA.  I agree with you.  You guess the error from playing a 130gm LP on a setting for 200gm at 'a few minutes maybe'.  I have done the calculation, assuming a 9 inch arm and a 1mm thickness difference (I haven't measured, but it's no more than that).  The answer is 1.8 minutes, so even less than your guess.  That cannot be heard.

My Simon Yorke Aeroarm has a dial for adjusting arm height on the fly.  There is a big stiff round knob.  I could measure the angular turn for say 0.1mm of change, mark a reference point adjacent to the knob, and set absolutely for each disc, having measured the thickness in the playing area with a caliper (carefully!) and written that dimension on the inner sleeve.

But I don't.  If Michael Fremer still used Simon Yorke equipment he would surely do it, and have a very nice record player as well.
