Hm, I took the anti-RIAA signal converted and run CD player into the phonostage. The RIAA curve was fine and the effect of the HF volume and frequency-depended quantization did not expose itself. So, it looks like the phonostage is not a problem after all. That is very good and… very bad as I have nothing to blame now. I did played with mono tonearm last week but it sound fine now, with no quantization and I think the stereo arms did sound fine after I finish with it. What the hell has happen with me stereo arms! How two arms might get “broken” like this if then never were even touched? Is it in cartridges? Is it tonearms (both at the same time!!!) Is it something environmental? The cables from both arms come to the same phonostage at the same entry jacks… is it possible that both cables pick some interference from something? The entire analog setup with max out volume has no more noise then it usually has, the noise is VERY low. You need to stay right at the mouth of horn to hear something. It is with 83dB gain in phonostage and 109dB sensitive acoustic system at… max out volume. My normal listening level is good 50dB down, so it is no noise or interference in cables. What else?

Well, I have fixed my analog. It has no relation to phonostage but as long I did blamed the phonostage above than I post resolution in the same thread. The reason was my dust tonearm. I do not have an idea why it did it bit as long I remove it the problem disappear. I have two dust tonearm on my TT the light-duty with brash and heavy duty with brash and roll. The light-duty dust tonearm was installed on the armboard of my Second stereo arm. Of cause there was nothing vibrating or shaking on that dust-arm but apparently my TT did not think so, even thogh I did not even use this dust-arm with stereo catrighes. If somebody would tell me that this light dust-arm installed on very platter and on TT like Micro 8000 would be able to effect anything I would not believe. However, the fact is fact – putting it back I got my “quantization” of sound back and removing it did remove the quantization. The mono arm apparently did not pick up the responses from the dust-arm as the mono arm instated on the other side of the TT or perhaps because mono cartridges are more immune against all of this.

Again, it is absolutely absurdity but it is what it is. BTW, here is a good concussion from the story – it shall be nothing, absolutely nothing, which might be sitting on the TT platter. I have a luxury of having wide and comfortable platter on which I have a habit to put a lot of superfluous crap. Not when I do it I would think twice, or at least listen once.
