@chakster : Why don't make the alignment calculations through internet? in that way you need not that some body, posts or me convince you about.

Btw, have you interest to buy a SAEC tonearm?

Why is everyone trying to strangle the new baby? It may well be that the new SAEC has been corrected with respect to headshell offset angle and alignment geometry. Why not keep an open mind?

Eh I got an SAEC 407 with the SL1000 I bought last year. Its a nice enough arm. I bought the EPA 250 to complete the Technics package. I also have a couple of Acos GST 801 to fill out my vintage arms. FInally, have a 12 inch Riggle String Theory arm on my main table, its fairly decent. I dont find the SEAC to be a bad arm

I have no intention to buy new 8k tonearm from any manufacturer, i like my Reed 3p "12 tonearm, it's new design, not a 30 years. But i like vintage tonearms as well, regarding vintage tonearms i'm not gonna pay more than 1,5k for any of them. I've learned from many audiogon threads that SAEC with its knife-edge bearings is not the best tonearm. And that's why i asked again is that good or not? Just curiosity, i'm not gonna buy Saec anyway. 

Sadly @dertonarm  is not posting anymore on audiogon, so i can not speak for him about his calculations etc. What i think is that size of the record does matter, especially for professional tonearms, if it was made for radio stations then the main format for new material on vinyl is SINGLES or "7 size first, all promo material for the radiostation released by the labels on singles to promote the best tracks from the LP long time before the LP will be even pressed or available for sale. This is how the industry worked back in the day. Singles with labels like "promo use only or D.J. copy" is typical for any radio archives. One song per side. I believe @dertonarm is right at some point, there could be a dedicated tonearm with dedicated alignment made for professional use for japanese radiostations backs in the 70s. 
@chakster : That tonearm can be used with any LP size as any other tonearm.

As I said I used my SAECs with different alignment parameters than the manufacturer specs. You can do that not only with the SAECS but with any tonearm. Maybe you need to learn a little about. 



Anyway, no big deal.
