I just arrived, and I already miss UncleKrusty. I believe all he was saying is that too often people are disregarding the flaws of their box components, while attempting to sooth the flaws with expensive wires.
That's not to say magic boxes aren't useful. I have no doubt MIT cables can help a system overrun with ear- splitting nasties caused by poor system matching. It has been brought up that MIT got a start in reaction to the terrible solid state amps around then.
Wire unbelievers, through default, are constantly seeking out better electronics. In response, active components are being changed for the better at an accelerating pace. For instance, relatively low cost class D amps are beginning to push older technology class AB amps to the brink of extinction. By the way, class D modules have arrived through the efforts of science minded people. ;)
Like UncleKrusty, I adhere to the component upgrade path. While friends have been busy tweaking their systems with expensive mods and wires, I have merely inserted in line the latest and greatest new electronics to go with my fabulous speakers.
Everyone I know, MIT users included, agree, my system is scintillating. I still have my old Kimbers.
