Thoughts on moving from a 1200G to Sota Saphire or above

@lewm, you are probably right. I used the term "harmonic distortion" as that is what it is called in the link I posted above which I believe is actually another way of expressing tracking angle error. Harmonic distortion is a misnomer. Thanx for pointing that out.

@chakster , if we are to believe the graphs in the link Stevenson is lowest right at the edge of the label (60mm). Very few old records go in farther than 65mm. In the middle of the record Stevenson is handily worse. Just from a look at the graphs I can't understand why anyone would use Stevenson. I must say that I have not tried to compare alignments from a sonic perspective because it is so difficult to do in a way that one could have confidence in the result. Angle error is a very simple issue to measure. I am sure we all agree that optimum is an angle error of zero and that the farther away from zero ones gets the worse the result will be. Whether or not this is something you can actually hear is another issue. I do not share your taste in tonearms but a lot of other people do. 

Very few old records go in farther than 65mm.

If you want to know there are at least about 10mm of music on the record surface on most of the 45 rpm (’7 inch) singles, the song ends at 53-55mm from the spindle (not as far as 65mm). On average ’7 inch single pressed in the ’50s/60’s (I just measured some of mine) the last 10mm before lead out groove is 1/3 of a song and there is music.

Mr. Stevenson was a mathematician, I can’t explain why till the present day Japanese tonearm manufacturers prefer Stevenson (or very close to Steventon) geometry. There must be a reason, right ?

I do not share your taste in tonearms but a lot of other people do.

Of course they do, because you will hardly find any better tonearm than boron/titanium Technics EPA-100 mkII or Fidelity-Research FR-66fx. You have never tried them yet @mijostyn

For years I contemplated upgrading from my Gyrodec. I really like it’s airy lively sound. Last year my local dealer had one available SL-1210GAE so I bought it. The first cartridge I used was an Ortofon Cadenza bronze. Now I’m using a Kiseki purple heart and it sounds great to me. I’m using an SME 309 tonearm and Lyra kleos with the Gyrodec. My gut feeling tells me that I wouldn’t like the Kleos with the SL-1210GAE.

@jdal I’ve thought about the Purple Heart and the Kleos. There seems to be more reviews/feedback on the Purple Heart versus the Kleos. What makes you think you wouldn’t like the Kleos on the 1210? With the removable headshell why haven’t you tried it on the 1210? 

@bfoura One of these days I probably will switch cartridges on both tables. The only cartridge that I used with both tables was the Cadenza bronze. To my ears it sounded slightly leaner with the SL-1210.
