Riaa curve

Sorry about the typo's, (need an editor sooner or later :-)

emperor = emperor's; fat = flat; just begs = begs; WAY-OF = WAY-OFF

Dear Axel: IMHO your tyre example tell me that you don't understand anything what is on my post or you don't really care about and it is nothing wrong with that because you like a person are a unique person as everyone else.

Btw, in our unit we make the RIAA calibration with the unit " hot "/warm to avoide changes due to temperature. Of ourse that in any audio item design we have to work between the parts tolerances, in some way this part tolerances are the limits to.

Dear Raul,
>>> ... in some way this part tolerances are the limits to. <<<
Exactly, what was on my mind also, tires have tolerances so have measuring gauges.
Pushing the envelope is fine by me - but maybe not always quite 'reasonable'?

I listen to CD on my 390S and then listen to a +/- 1dB 'quoted'/spec. RIAA module, and all I hear is NO colouration other then what the different carts produce.
The least colouration CD vs. vinyl is provided by my Windfeld, known to be very neutral.

Then I listen to a S1000ZE/X that has colouration (more low end than any same CD), but it is nicer than CD.
I actually cannot easily assimilate how +/-0.0075dB error is going to make this any different.
Maybe if I put my head in vice?
The variations in moving my head will actually be bigger than that 1% RIAA error... hm.

Raul....Do you know the spec on the RIAA equalization when the LP is cut, and the frequency response of the cutter, its electronics, and the recorder that made the master, and the microphones?

Dear Axel: IMHO all your statements are out of my main/deep point of view, please re-read my post and try to understand what I really mean because maybe I can't explain in the right way.

Btw, I understand that you can't imagine how could you hear a tiny deviation in the RIAA when you never experienced on the same phono stage making RIAA deviation changes. Well, over the time in our design uit I have the opportunity to have that kind of experiences and that's why I know that we can hear those tiny RIAA deviations.
