Mark Waldrep of AIX Records was on hand with Tearing it Up, the Albert Lee performance film that was recently featured in Stereophile’s pages. Waldrep also showed off a processor called the Realiser (ca $3000), from Smyth Research, a listener-adaptive device that, in this demonstration, allowed me to hear surround effects just as Mark Waldrep hears them in his own installation. Even this headphone-phobic monophile was impressed.
