personally, i though the wine study and geoffkait's audio analogy was very interesting and probably sound. it's seems logical and intuitive that spending more creates some enhanced neurological responsiveness to pleasure, otherwise $500 wines and $5000 speaker cables wouldn't exist.
Bad news for audiophiles?
In new study a bottle of wine priced at $90 tastes better than a bottle of the same wine with price tag of $10.
