There are indeed engineers who have proposed some very sophisticated measurement techniques to better correlate with listening. Sometimes these get published in journals such as from the AES or IEEE. How many DIYers regularly read these? A couple of examples off the top of my head: One technique is to use test signals comprising a huge number (hundreds or thousands) of spectral lines (frequencies) and then see what garbage the amp makes in response. A fellow named Cheever has proposed a new harmonic weighting system called TAD. I’ve been working on a phase intermodulation measurement system.This is one area where the solid state guys may be more open-minded than the tube guys. Try some searches outside this tube forum. I'm NOT saying the matter is closed, FAR from it. I’m just saying that there are some people trying. Are we listening to them or do we prefer to hide our heads in the sand and call them deaf?
