Tonearm adjustments on the fly

VTA and SRA are different technically, and in audio you will find incredibly tedious and impressively pedantic polemics explaining in excruciating detail why they are not the same. Functionally however when you adjust VTA you adjust SRA, and vice versa. One more thing people who understand a lot less than they think love to throw at noobs to keep them from leapfrogging them, something you will have no problem whatsoever doing, provided only you listen to me and not them.

This is all so freaking simple you have no idea. Nor will you, not for many years (if even then), if you keep on reading drivel like what you pasted above. The problem with that kind of stuff, it takes me ten pages to explain why you should never have read it in the first place. Ten pages that could have been spent going forward instead of correcting mistakes from the past.

Oh, sorry, there is one thing I did miss that should be fixed. The two things you want in an arm are VTA on the fly and a hard wired integral phono lead. Cartridge output is the faintest in all of audio. The last thing you want is a delicate signal going through a lot of connections. So hard wired phono lead, no detachable arm wands or head shells. 

Probably not what you’re looking for but my Schiit Sol has all of those features and punches way above its weight in the sound quality category. Mine was the last run of pure b-spec after all their beta testing improvements and then went through with the recommended upgrades and a great cartridge for my budget. Biggest difference in the sound quality came from proper vta/sra and the azimuth. Getting that right will get the tonal balance spot on and makes that center image snap perfectly in place. I know lots of the hifi crowd scoff at Schiit for their focus on reasonable cost gear but holy crap does it sound good. If you like tinkering to always try and get a little better performance and if you can get your hands on one, they’re worth it for sure. Just my thoughts as I sit here tapping my toes to the music.

VPI arms are easily adjusted....once you found what you like why bother

This last reply beat me to it. Most VPI tone arms allow VTA adjustment on the fly. And decades ago Technics produced some gorgeous tone arms with infinitely adjustable VTA that felt like adjusting a lens on a fine camera.

Most of us adjust VTA for best sound so it doesn't ultimately matter in this case what SRA is.

By the way always adjust vertical tracking force 1st. Changing VTF will also change VTA. In fact if your arm doesn't have fine vertical djustment you can use VTF adjustment for fine tuning VTA if your arm permits fine tuning VTF. First set up the hight of the arm for a VTA that sounds good after setting the VTF in the middle of the recommended range. Then very slight adjustments up and down of VTF are also fine VTA adjustments that should have no significant affect on cartridge tracking.
