Just an update on the progress I've made based on Doug's and Speedy's recommendations...
Although the 'brightness' issue on my ZYX/2.2 setup has not completely gone away, I believe I've made some progress. Since Friday, 11/11, I've been fine tuning SRA and VTF settings and have logged a total of 18 critical (alcohol-free) listening hours and damaged about 6 decent 180 gram LPs due to repeated playback of certain 'test' tracks. A small price to pay for the improvements gained in my opinion. I also played around a bit with the impedance setting (lowering) but was not happy with the outcome so it's still at the ZYX recommended 100 ohms.
A VTF setting of 2.05 works best in relation to my current 'almost parallel' SRA setting. Previous VTF was 1.9 and SRA was slightly 'butt lower'. All tests were done using 180 and 200 gram vinyl (both 33 and 45) but I have marked the scale to compensate for 140 gram pressings. I was able to tame down a bit of the brightness -- say about 30% (without any noticeable HF rolloff) with the new settings.
I'm now ready to move on to the next stage -- damping fluid, which appears to be the more tedious task. I don't intend to play around with the SRA and VTF settings in relation to damping fluid adjustments (sounds like a true test of patience). Should be able to report back sometime next week.
Thanks again for your recommendations.
