Hold on, are you saying that manufacturers of phonostages who claim that they run RIAA curve with precision of 0.1db are full of shit? Ok, take the Fifths and do not answer this question.
There is nothing wrong with making the RIAA EQ very precise (but not necessarily anything right either)...

I did not know that middle turnover was a subject of valiance. The curves themselves were pretty much random in that time but I was under impression that they all cross zero at fixed point. If it is not so then it would be VERY VERY difficult to set the proper equalization by ears only.
I have researched the subject of LP Equalisation in some detail. It is not a particulary pretty or inspiring story.The middle turnover has been found as low as 250Hz and as high as 600Hz if we omit the real oddball stuff.As the Mid turnover acts a lot like the old Quad Tilt Control, it is not that difficult to tell the sonic effect.Ciao T
