Something is indeed wrong. People who hear differences have an imperfect DAC. But who has a perfect DAC? As you have stated, the way to improve the sound of compressed files is to increase the isolation of the DAC. But how?
One expensive and potentially imperfect way is to spend big bucks on a super high quality DAC, reclocker, power isolator, etc. An inexpensive way is to expand lossless compressed files back to their original form before the music starts playing. One can do this by storing them that way on the hard drive as some people are doing (which costs a tiny amount for extra hard drive space) or by decoding them into RAM (which costs a small time delay when starting playback with a memory player). There are pros and cons of all these approaches. IMO, it's best to take a practical approach and not a theoretical/religious approach.
There are real arguments between the various lossless formats. Mostly they have to do with platform support (O/S and applications), features (e.g. 24 bit samples), bugs, and trust (in supplier). Perhaps there are differences in CPU resource consumption and indirectly in sound quality on many systems, but reports of this type are rare. Mostly, people compare sound quality of lossless compression vs. uncompressed PCM (WAV or AIFF).
There is also the possibility that some of the people who hear the differences are deluded. These people can choose fancy hardware or simple software changes, according to their budget/ego.
