Allpass Filter vs. Straight Wire [URL="http://www.provide.net/~djcarlst/abx_caps.htm#psacs"]http://www.provide.net/~djcarlst/abx_caps.htm#psacs[/URL] This test is awesome. It totally kills audiophile thinking that a minimalist signal path is superior. There are people who believe that capacitors in the signal path are bad sounding and they prefer DC coupled stages. Here's a test where not only did they use resistors and capacitors to make the 'all pass' network, they really hit a home run by using the worse capacitors possible for signal path, the ceramic capacitor. In spite of this bad design, people failed the ABX and could not identify this all pass network vs. a hunk of wire..
