Hi guys, I will definitely delve into the SQ a bit more with a set of criteria as Nirvana started to outline by means of one more poll. I just don't want to take away from the interest and momentum with this poll. SQ warrants a poll on its own, I think. In my own mind, I am working towards a comprehensive and inclusive framework to break down SQ in a number of distinct factors, with primary determinants, secondary factors and maybe tertiary factors. I will cover aspect such a coherence, tone, tempo and texture etc in primary determinants; extension (both bass and high freq), transparency, detail, macro and micro dynamic ability etc in the secondary list and the maybe's include linearity, phase coherence, etc in the last tertiary category. Soundstage could be broken down in width and depth etc as well.. if you have ideas let me know..
