In Reply to: "VTA adjustment is actually a neurosis NOT a technical adjustment." posted by xyyyy on September 11, 2006 at 16:56:48:
However, SRA probably varies as much as ±3º among different LPs, so I don’t bother with it. Anyway, I’m presently using a cartridge with a conical tip, which is impervious to SRA.
Follow Ups:
of one being used to change the other? How does one change SRA?With a given VTA change how much does the SRA change?
I think Mr. Gandy is more right than wrong.
Their relationship is fixed by the glue that holds the stylus to the cantilever. Consequently, changing one changes the other by the same amount. However, they are totally different and otherwise unrelated parameters.I think Mr. Gandy is more right than wrong about VTA, but not SRA.
So if one changes VTA and therefore SRA ....I question whether the manufacturer of stylus/cantilever assembly, btw generally not the same as the cartridge manufacturer, knows or cares about SRA.
So if VTA is unimportant so is SRA and vice versa.
Can you explain further? It doesn't make sense.
If you don't think it's important, that's your business. I'm not going to play games with you.
SRA can ONLY be user changed by changing the rake angle of the cantilever to the record surface, no? Or is there a different way? How one changes this a different subject perhaps but the subject of this thread is VTA commonly changed by raising and lowering the pivoted end of a pivoted tonearm.So if they are permanently locked together a change of VTA must result in a change of SRA. If a change of VTA is unimportant then the subsequent change of SRA is likewise unimportant. No?
Now if you disagree with that please explain yourself.
That was a real non-answer.Let me put it this way:
If Roy Ganday says VTA is not important then he must also think SRA is unimportant, to be able to change by the user.
Conversly if SRA is important, to be able to change, and VTA changes it then VTA changes are important.
Now if you really meant that the parameter of VTA is unimportant but SRA is important and .....it still makes no sense.
Are you just hung up on the terminology?
Does a change of VTA change SRA?
All other factors like record thickness, temperature, VTF etc. change VTA and consequently SRA. But a change of SRA is ONLY possible with a change of VTA.
I guess some folks just have a problem saying ... opps!BTW, I've found VTA changes *do* translate to sonic changes in my system ... could it be because I don't have a Rega arm? Oh wait, logic check ... opps! LOL
