Adjusting SRA using macro lens vs microscope

What I find interesting is the focus on correct SRA whether set by sight or sound but the consistent dismissal of the anti-skate issue. We are so focused on SRA and setting it for each record but everything from disabling anti-skate to setting it to match VTF seems appropriate.

Dear Wntrmute2: As other cartridge/tonearm set up parameters the anti-skate is an important one that we don't have to dimish because it has a very precise role in the whole analog set up subject and not only because VTF.

As this parameter IMHO the Azymuth set up is extremely important and critical and many of us are not given that importance and I would like to say that many times if we " play " a little with Azymuth set up we could be surprised how tiny azymuth changes can make a high difference, I think we need to " work " a little on Azymuth set up too.

Regards and enjoy the music,

Hi Glai, which usb microscope did you buy?

The scope is good to see what your ears are telling you. SRA is more important with some stylus's than other's. Doug, it may be fun to see where your SRA is at with a few albums just to see.

Interesting read which I am sure some of you have already read.

As Raul said everthing changes when SRA is changed. Some tonearms moreso than others.

I have the Dino am413T with flex stand. It is one model up from the 313 used in Fremer's article. The magnification is the same but the camera has more pixels. The web site said measurements would be more precise because of this. It is only$40 -50 more.

Interesting video from Ortofon about the SLM process.

With all the talk about SRA and the A90 and getting to 92 degrees. It is interesting to see that in this video the A90 / tonearm is parallel.
