I don't think I'd say "beautified", but one of the advantages of having mid-fi or low-fi equipment in addition to a top of the line setup is to be able to comfortably listen to poorly-produced recordings and low-quality MP3s.
The things that make high-end gear great -- equipment capable of so much detail that the musicians all but appear materially in front of you -- are the same things that can make poorly produced recordings sound distractingly false, noisy, and artificial. When it has immense dynamic range, it can make overcompressed recordings sound flat and noisy; when it has incredibly even (perceived) frequency response, it can make the tape hiss and surface noise distract you from the performance.
It's not a universal truth, of course. Some music is too beloved to allow the tape hiss to get in the way, and some equipment can be both incredibly resolving and very forgiving. But there's frequently a tradeoff to be made, on top of which there's simply some music that works so well with non-audiophile-approved kit that there's no incentive to upgrade.
