Raul, Please convey my apologies to the Lofgren family for any perceived but unintended insult, but I also do not think it is insulting to Lofgren to point out that his work was primarily aimed at solving the geometry problem of how to minimize TA...

Dear Reimarc, Thank you for this report. You or a member of your family must speak Japanese, because in my indirect dealings with Akimoto-san, I learned that he does not communicate well in English. Nevertheless, I too bought my Viv directly from ... 
Will VPI's Classic 3 sound much better with a SUT?
Jason, you might review your own early posts here. You consistently stated that an MC phono stage adds 10X gain. Now I see that you meant to say that a SUT typically adds 10 X gain.  If so, ok.  
Will VPI's Classic 3 sound much better with a SUT?
For only 60db gain, I'd want a cartridge with a bit more than 0.5mV output. And tablejockey, I am sure that was a typo but my point is that 60db gain from an 0.3mV source gives 300mV or 0.3V.

I get it. Sorry. I don't know if bearing friction would double, because for most tonearms the vertical bearing friction is different from the horizontal bearing friction, but I guess it would be increased. But like Dave said, and in spite of what... 
Will VPI's Classic 3 sound much better with a SUT?
Jason, do you really believe this?: "Most mc stages amplify a mc cartridge’s voltage TEN times for use with a typical phono stage!" Because most MC gain stages supply at least 60db of gain to the signal, and frequently much more than that, which c... 
Will VPI's Classic 3 sound much better with a SUT?
Jason, I don’t know where to begin. But 60db of gain provided by the MC stage in the Fosgate equates to a 1000X voltage gain, and a 10X gain that you claim would be insufficient for any phono stage ever. 0.3mV multiplied by 1000 = 0.3V Also, I di... 
Will VPI's Classic 3 sound much better with a SUT?
You don't say why you are thinking about adding a SUT to this system.  That would help.  Also, as a rule you don't match a SUT to the TT.  The TT doesn't give a hoot what SUT you choose to use, and vice-versa, but I understand in this case that th...

Sorry for not completing my thought above. The skating force arises due to friction between stylus and groove. Therefore the need for AS does not vary with stylus velocity. It does vary in both magnitude and direction with respect to the angle by ... 
Discuss The Viv Lab Rigid Arm
Dogberry, a warp, or any other change in stylus velocity which is actually happening throughout the course of replay, has no effect on the friction force. The equation for that force is simply the coefficient of friction for the two materials that... 
A budget turntable exploration
The key to your success (defined here as satisfaction) is or may be in great measure due to the fact that the Reference 3A Da Capo is a superb speaker that could probably reveal any upstream improvements.

Will I be burned at the stake for witchcraft? I am going to buy some asbestos pants. I do own and regularly use 5 other tonearms, all of which are conventional pivoted overhung types, some that you like and some that you dislike. Your vitriol is p... 
Recommend an MC cartridge
Reimac, until reading your post, I had never heard of this new Miyajima cartridge that you purchased in Tokyo. I am a little disappointed in myself, because I just returned from almost 3 weeks staying with my son in Tokyo, and I would have loved t...

When you use the term "optimized", do you refer to consistency of the manufacture of a given model or do you refer to a particular construction (body materials, cantilever type, stylus shape, coils, etc) that you deem to be optimal?

FWIW, I had my Grace Ruby re-tipped by SS using their top line ruby cantilever/OCL stylus option.  When I got it back, suffice to say it did not sound "good".  I notified Peter of my dissatisfaction, and he agreed to have a second look at the inst...
