And I must confess I often equate cynisism with realism. An objective component review would indeed be hard with ABX. I have always been suspicious of ABX, as it, from a purely practical standpoint, simply is too difficult to manage. It's almost as hard as doing a doubleblind study on the effects of oil massage. Fugedaboudit. I think a more fruitful way is to measure, measure and measure again. We would perhaps need to develop more methods of testing. For instance some people seem to believe that single test tones are not enough. Maybe they have a point. Well, then develop a different method to investigate that. It's not just about proving things, it's also about explaining why it is a proof to the people that don't have the background to understand it by themselves. And hearing/seeing is believing. Never waste time with subjectivities. Always find hard facts and build on those. Yada yada. (Why do these discussions always come to this?) But I actually believe the optimal testing method is already since long invented; the null test. It's extremely powerful, but more importantly; it's also extremely transparent. Everyone understands it and it's hard to argue that the test is inadequate, when you actually measure the entire audio content of some complex piece of music and compare this to the source. What could possibly be missed? And if you get a difference at the -120dB level, this would be very difficult to hear. It's easily tested, just attenuate a sound in a sound editor by that amount and see if you can hear it with the volume knob unchanged. If you can, then add a masking noise and we're done. By the way, doing a null test with the the entire audio chain would be very unforgiving. There is a reason that we never see distortion figures for speakers, in the way that we do for amps. Not to mention the listening room.
