I recently found out that there is a Crossmodal Research Lab at Oxford, in the Psych. Dept. headed by Charles Spencer.

Currently, the publications seem interesting by analogy - e.g. food tastes are influenced by the cutlery used, and the effects of the frequencies in music on enhancing different tastes. Taking a swing at the audiophile market would be a public service.
Anybody want to ship him some DACs at wildly different price points?
i'm lovin audiophile DACs
