@atmasphere To the third, a correct answer requires a correct question- the **response** is not raised; the **pre-emphasis** is, and by about 5 db (so the simple answer is thus 'no'). Remember that the curve is just that and is the amalgam of three timing constants. The range of frequencies to which you refer is the area where the response is relatively flat compared to the rest of the curve. It isn't flat because of the ordinates of the timing constants. So its a gentle curve in that range, and the **pre-emphasis** is 'lifted' by about 5 db over that range, not 12.
There are plenty of images on the web. Fig. 2 of the article at the link below is pretty good- you can see the 5 db or so rise in the pre-emphasis in the range of frequencies about which you asked:
We are talking about just two time constants that are at 500 HZ and 2200 Hz. Surely you know that time constants or frequency corners are defined points where the response is 3 db up or down. Since these are first order they eventually (within the audio range) come to be 6 dB. Thus 6 db rise for the first pole and 6 db loss for the second. 6+6 = 12 dB.
This is also confirmed by graph you presented from Stereophile.
I am simply trying to tell readers that the high end of a disc is cut 12 dB higher above 2200 Hz. Also that the RIAA playback curve they are accustomed to seeing is for a magnetic (velocity) cartridge and the one for a displacement (strain gague) would be only 12 dB top to bottom as apposed to 40 dB.
How can you disagree?
