Mijo, I guess it is my fault for not having fully explained my reasoning. When you see those impressive flat lines on the B&K print-outs that used to be supplied in the box with new cartridges, as far as I know they have to have been created using an input adherent to a compensation curve a la RIAA and then the output of the cartridge has to have been filtered according to the converse of the (RIAA) curve, in order to generate that nearly flat line between 20Hz and 20kHz. So what you are looking at is the sum result of whatever errors there were in the encoding of the test LP, in the cartridge's response to the input, and in the final decoding. The graph does not really tell you what the cartridge per se does to the input signal. When you're talking about differences of 0.5db (voltage db), those distinctions assume some importance. And then of course you don't get that flat response at your listening position even if your own phono corrector is perfect. Which is one reason why we don't all love the same cartridges. Imperfections are different for different systems, not to mention the bias that we carry in our heads, the magic balance each of us thinks is most real. My two systems definitely sound different, but not too different. Both of them are consciously put together to give me a close approximation of reality which endeavor brought them close together sonically, but they get there in different ways. Once I had reached that point in their development, I became much less willing to tweak them or experiment with new equipment, although every once in a while I do that, as you know.
