I checked out the Realiser room at the AXPONA here in Atlanta and came away quite impress. It is the best surround sound stimulation I've heard. Their head tracking technology is nothing short of amazing. I wish they will make a unit with a retailed price of $1500. $2600 for the unit alone w/o the headphones is a bit pricey for most people including me. My HT system which consists of all very good used components (Sony STR-DA9000ES, and Paradigm Ref. Speakers) are almost identical in price. I talked to their rep and the price may go soon. They mostly target the audio professional for the most part.
