I'm with Peng on this, but would word it differently:
"I trust my ears, but only when I am blind of what I am listening to"
I think most here are familiar with the McGurk effect where even after you know what the sound is you still hear it wrong because your eyes over-ride your ears! But for anyone who doesn't, here is a fun video demonstration:
My personal audio experience of this (vision over-riding hearing) happened when I got my RBH T1/R's!
These speakers are a whopping 13" W x 30-5/16" H x 19-1/2" D with 4 mid-woofers and 3 tweeters (the top half of the T2 towers):
At the time I had a pair of Canton Ventos 820.2's set up. These are 7.7'' x 11.8'' x 11'' (close to the same size as the A. Jones Pioneer BS-22 bookshelf speakers):
I was really enjoying the expansive enveloping sound-stage of the T1/R's! They fill a room like nobody's business! Dynamics to die for!
@TheWarrior was coming over for a visit and I had the comparison set up (level matched instant switching),so I blind-folded him at the door and led him to the LP to do the comparison.
He liked the Canton better, which is not such a surprise, as:
1) the Cantons have one of the best tweeters I have ever head and I knew the soft-dome ScanSpeak in the T1 was not as pristine as the "ceramic" tweeter of the Canton (RBH has since stopped using soft-domes in their best speakers),and
2) The T1's are sealed speakers, rated 50Hz-20kHz (±3dB) and really intended for use with their sub-module (or equivalent)! The Vento is ported and rated down to 32Hz (no +/- dB specified),and it puts out more bass!
Just before he removed the blind-fold to see what speakers he had been listening to I asked him if he got any sense of scale among the speakers, and he said "absolutely none!".
This totally shocked me! I had been listening to them for over a week and "knew" how the T1's effortlessly filled the room with immersive, enveloping sound!
I had to admit that that was all an artifact of vision! The T1's are visually imposing and dominate any normal room in a "take no prisoners" kind of way! It was that, and not the actual SQ that caused me to perceive such a enveloping sound stage!
So, I am astutely aware of how expectation bias can influence hearing perception!
I was 100% certain of what I was hearing and knew it would be totally obvious to anyone who took 10 seconds to listen to them! However, when confronted with someone who had listened for almost 2 hours to a wide array of music saying they perceived
no difference in sense of scale between the two speakers, it was an experience with profound implications!
