Not aware of many people who aren't into the hobby. From those who build everything from scratch to checkbook DIYers who pay others to do it all. Most of us are too poor/tight to just spaff $$$$ at the audio store after all.
For me I can list at least a dozen other things that need to be improved before my DACs so my priorities are clear.
Guys like me aren't exactly hobbyists! Rumor has it you can actually make a living in this field.
As to blind testing, one of the things I find handy are the honesty detection tests. "Do you prefer A or B? Do you prefer A or C? Do you prefer B or C?" A,A,B = valid, B,A,C = not valid. Obviously the honesty verification questions should be buried in the other tests and not always in sequence. The other test is "Do you prefer A or B? Do you prefer B or A?"

The "valid" "not valid" distinction can only be made if transitivity is ensured in a test or test sequence.
In one-dimensional (directional) tests it will work as described but not so in multidimensional tests.
So if a test uses multidimensional evaluation (as listening to music and asking for a preference is) transitivity is not given, because in each comparison different criteria (along different dimensions) might be choosen for the preference decision.

You are certainly not the only one here that has made a living as an EE, at last count I had only a little left to get to 10**9 $ of products shipped.
Per pound, that's probably how much my little nylon gear will end up costing me to cut..

I agree, I like to run three way test sets for subjective test cross checking, and also as objective test cross checking.
Experimental errors are revealed (confounder changes caused by the likes of connections or grounds or change in AC mains noise etc can be discriminated), false positives are culled and correct positives are reinforced.

With what device?
You don't seem to understand what level matching is when comparing audio electronic components.
What does that have to do with level matched double blind listening test?
I think the level matching suggestion is WAY over blown. If it is a LIKE contest, you might like the louder as fuller, deeper bass heard. Some like that. If the louder causes your ear to distort more, then you might not like it.
Somethings being listened FOR dont change with small level changes. Or even larger level differences. Sound stage doesnt change its character much with small differences in level.
If listening for Accuracy and you learn to compare to real acoustic sounds, you can more easily determine which DUT is more accurate reproduction.

Now there is an honest answer. Much better than pretending to take the high road as a music listener first and foremost as the reason; Lack of money or just very tight.

If I have 90 minutes free of an evening and chose 70 of them to listen to music and 20 to poke something with a soldering iron I feel that entitles me to say music comes first?
If I can get my electrostatics headphones hooked back up then I might be able to do both, which would be bliss.

The truth is more important, the world does not revolve around envy. I don't pretend please keep your comments to yourself they probably offended many here.
