People often complain that threads lack substance or discussions are only superficial. I think the distinction between "natural" sound and "hifi" sound is extremely important in this hobby. Definitions are not always agreed upon, and some reject the term "natural" outright as having no meaning or being whatever one claims it is, but I have tried, at least in the context of my own two system threads, to make this distinction very clear. That is, from my point of view. This distinction represents well my evolving thoughts about sound in general, and reproduced sound by high end audio systems in particular.
I am pleased that people can hear the differences in those videos to form and then often share their own opinions.
