Sight and Sound Question

Well, it looks like I hit the save button too should be Sight & Sound Question

If you spend a lot of time over at Audio Science Review you might come to the conclusion that what you hear is all about the numbers and therefore anything you prefer that is not supported by the numbers must be incorrect or at least misunderstood. Here at Audiogon, the numbers matter but maybe not as much as personal experience...your house, your room, your gear and your music.
Psychologists might even suggest that is not even "that simple"...that sight and sound also influence each other.

So, my question is an easy one...has it been your experience that if you like the looks of a particular piece of gear...speakers???? whatever??? that somehow it actually ends up sounding better than gear that is less attractive?

Quite so! And that is one of the reasons that blind listening tests have limited usefulness - unless you are in the habit of only listening blind.
Hasn't been my experience. 

Case in point: I really like the looks of Harbeth cabinets - the eucalyptus veneer option and the sort of new-meets-old contrast of their driver frames and offset ports. But after comparing them to a competitor I settled for a rather boring cabinet in boring walnut finish.

Recently auditioned the B&W 800D3s. I thought they sounded great but are borderline hideous. 

I've been involved in this type of work and the whole point is that the human perception & preference systems have cross-talk that literally makes it impossible to completely separate out your response to any single object. 

Thus, some of the positivity created by the visual appearance is mistakenly attributed to the sound.  The only way to completely prevent that is to listen blind.  Of course you're still going to be biased in your evaluations by all the other positive and negative experiences that are co-occuring with the listening experience.  The brain is simply not able to fully separate out the unique influence of any one variable.  You can do things to improve accuracy, but there's just too much going on for the system to be perfect. 

Just like in music reproduction, everything matters.

P.S.  The antidotes and comparisons listed above, while relevant, are not really informative.  You would need to hear the exact same item and perceive it as visually beautiful in one condition, but visually hideous in the other.
