Yamamoto HSA-01 headshell/head amp
With Dave Slagle’s head amp driving the MM stage of my Silvaweld phono, there is no problem at all, and it sounds great. With my modified MP1 and with the 3160, I get good results but with a very slight sense of strain. On LPs with inherently high... 
Yamamoto HSA-01 headshell/head amp
Here is my report on the Yamamoto HSA-01 self-amplifying headshell, used so far only with the Ortofon MC2000: Don’t do it. There is too much hiss or white noise at SPLs even below satisfactory. I suspect this may be because Yamamoto says in the fi...

"I had to change to pivot alternative to reach the rigth bass range and to do this the second best alternative was and is use the Löfgreen alignments that puts that stylus tip nearer to what the LT does: NO MATTER WHAT. .." That depends, doesn't ... 
Anyone adjust cart set up due to ambient temperature changes?
Could you tell which did the most good, changing VTF or raising the pivot? Any way , I don’t know what your baseline ambient temperature is, but an increase of 8 degrees F in our house would drive me away.

I’ll drink to that. But I will add that it does or did make a positive difference when I carefully aligned the cartridge using the L-shaped template, vs when the same cartridge was out of alignment by several mm using the same template, due to my ...

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...
