The value of analog v digital isn't measured in 20 minute increments. There's no reason why someone can't enjoy digital more than analog for a particular song, record, group of records. It's really about the long term listening experience. You could have played that digital for another 20 minutes and everyone would have still been praising the sound but asking to go out to the bar. Play the analog for 40 minutes and they would want an hour more. Or with that SME, you'd have a hard time getting them to leave.
