Paul, this is one of the areas of audio where we have to wade through a sea of mythologies which have no factual basis. These "big improvements" you may have read about(often extravagant language such as "huge", "night and day", etc. is used)tend to disappear when the listeners actually have to "trust their ears" in a controlled blind test. An example is the
Stereo Review blind testwhich has been cited here before, and which enraged some audiophiles, but opened the eyes of others who were able to get their heads out of the sand. Note how the typical descriptions of clear differences heard before the test disappeared when the labels and price tags disappeared.
