How could High End audio be improved?

Another perspective: Audiophiles who have embraced a quality HT setup in their homes have been able to expose people to the soundtracks of films reproduced by quality equipment, to other forms of recorded information. People who enjoy watching movies with us will often inquire about the equipment (located out of site in a closet just outside the room), which will lead to a remark about the turntable (sitting in the main room on it's own rack on top of a two inch thick slab of stained and polished maple), which will lead to a request to hear something played on it. I allow the guest to choose what they would like to hear, and let the whole side play. Many folks I know who previously thought paying large sums of money for a "record player" as absurd, have become interested in getting more value and quality for their money than can be had from mass merchandisers. Those hard core 2 channel only (I count myself as one: I am vinyl 1st, SACD 2 channel 2nd) have to give some credit to the HT crowd for giving more people the opportunity to appreciate high quality equipment. It is easier to baptize someone with a visual image to go along with the audio, than trying to get someone to sit and listen. It gets them interested, asking questions, and perhaps becoming disciples.
