I spent years trying to improve my HiFi, eventually I decided it doesn't make a bad song better no matter how good it sounds, the situation you're listening in makes a far bigger impact, ( like down the pub in good company on a crappy juke box, the backing track to an advert or TV program, or even driving the car).
I use ad based Spotify, sounds fine to me, mind you, I am a bit deaf these days.
Which brings me back to the Revolver remix, yes it sounds better, but once the novelty of trying to decide if you can hear something that you couldn't before wears off you're back to listening to a great album, would I shell out to buy it? no.
