The main reason I go to audio shows is so I can have a reference to compare my system to. You get to listen to expensive and professionally tuned systems and determine where your system stands. If you don’t listen to other systems how could you possibly know? Highly recommended.
Shows/hotel rooms are terrible places to audit what some equipment is capable of. It is best that such audits happen in the houses of audiophiles with treated tweaked rooms.
The best example of this is a blind test in Spain where they had 30 audiophiles do a blind listening test of a $500 front end. A dirt cheap $200 Crown, class D amp, using the cheapest cables vs. a $12,000 front end. Conclusion of the test: 1/3 picked the cheap system...1/3 picked the expensive system ...1/3 couldn’t tell a difference.
The buffoon in the white coat getting high n mighty on the linked vid doesn’t seem to understand that there is a big difference in the test subject pool.
For example, i have 5 violins, an instrument i’ve been closely associated with for 40+ years. I could play something on two of them and no one in the room would hear a difference between the 2 instruments. But, i sure as hell can...If you played some violin solos on different equipment, it is fairly easy for me to pin point which is which. Play something else like....some twangy country or Diana Krall squealing away and i could give a rats behind on what i heard or not, failed a blind test or not.
It would be silly to say that every test subject out there is trained the same way, has the same ears. The typical "audiophile" is maybe not the best test subject if you wanna get hardcore with the blind test (play it to the bone).
