Do You Have a Favorite Disk to Set VTA/SRA?

So - Wouldn't the average audiophile's life be easier with a spherical stylus? Just set the overhang and a reasonably parallel arm tube and you're pretty much done. I wonder how compromised the sound would be if a high-quality spherical stylus were put on a good cartridge, say $1500-$2500. This is of course for those not willing or able to achieve perfect alignment and reset VTA for each record. I haven't done a survey, but I think sphericals are used on lower-priced carts to keep the price low, but why not on a better cart? What do you think, Doug?

I have used this method as well as the record mentioned to set VTA with good results. http://www.tnt-audio.com/sorgenti/vta_method_e.html

I am more of a set it and forget it kind of guy. Mostly because I can't hear such small changes from my turntable which is not in the sweet-spot but off to the side quite a way from the listening position. One of my TTs has a Terminator tonearm which allows easy VTA adjustments on the fly but I do not wish to stand there and try and dial it in for each record. I'm not saying it isn't worth it for some, but I'd rather be listening!

That said, I have used a USB microscope to confirm my settings by ear and they seem to be very close (within 1 degree) to the supposed magical 92 degrees. OTOH, who decided that the playback SRA needs to be the same as the cutter angle? The cutter angle is a compromise between all sorts of parameters including getting the tool to cut in such a way that the waste material curls off properly. Those with machine shop experience will recognize that. Some of those factors have nothing to do with playback! Just an opinion. No facts involved!

The setting on the fly isn't an issue for a lot of arms. The issue, for me, is running back and forth between the table and the listening position to hear what my adjustments are doing~ thus, the overwhelming value of a remote controlled arm height adjustment. Because, if you are going this far, and doing it record by record (respecting Ralph's point that no record is cut at the same angle), it just becomes a giant PITA unless your listening chair is adjacent to the turntable; not a set up I've ever run. Has anyone else? Ralph: are you dialing in and having to jog back and forth between the table and your listening position?

I don't generally change the VTA once I have it in the right area (IOW, proper tonality, no breakup). The arm/cartridge resonance is far more important IMO; once that is right and you have otherwise proper setup, the SRA is not going to be particularly critical. If you set up for 92 degrees you will have a good average.

The really important thing here is that there are cartridges where the stylus is installed improperly in the cantilever; if this is the case you will never get the cartridge to work correctly as it is defective. So actually working to get the 92 degree angle is a good idea even if the LPs themselves are not cut exactly at that angle.

The amazing thing about the LP is how well they work, especially since so many aspects about them are compromises. Overhang is a good example, and SRA is another.

With help of headphones you don't have to jog between sweet-spot and equipment stand.
