Not sure how many of those demo track threads we already have…and you maybe should have left out those examples of Barber, Krall to not prevent some from posting
But here we go (non classical and mostly non analog versions for now, although several were recorded analog):
The Bubbles track is really strange, my wife is also always fascinated by it, but I usually avoid to play too technical/test signal orientated tracks for normals.
This is to show nice music with a big, ambient soundscape, a lot going on on the soundstage and deep, non superficial bass:
This is to show holographic, touchable sound:
This is to show prat and dynamics in opposite to dynamic range:
This is to show prat in terms of rhythmic finesse of a singer (she does it fantastically):
This to show dynamics, room ambiance and natural sound of drums (the vinyl of this one beats the digital easily, but the digital is still great):
This to show the need of a good setup to make normal music sound fascinating (most will have a flooring experience listening to the same track at home) and to show the difference of digital/analog and different masterings. The Analogue Productions (AP) SACD sounds intimate, ambient and emotional already on a good setup, but just normal and unspectacular on an average one. The same AP 45 RPM vinyl has more air and atmosphere, strengthening the fascination of this piece. The Classic Records Grundman mastering on 45 RPM then beats both by far and drags you in an enveloping way into the set.
This to show how sounds can make you think you’re on drugs:
This one to show how great tracks, everyone loves, can sound marvelous and lifelike:
