I’ve been able to hear many ‘high end systems’. In my experience there is a correlation between price and sound at a macro-level that can make the difference in the experience from interesting to awe inspiring.
Electronics have their own characteristics (e.g., Audio Research, CH Precision, Jeff Rowland,et.), as do speakers (Wilson, Stenheim, Focal, etc.) and overall system set up including use of subs.
The most impressive to me was CH Precision and Stenheim. In the end, it’s personal preference and I have had awesome experiences listening to systems designed differently than mine.
