Not only can you not tell the difference between analogue and digital, you also cannot tell the difference between lossless and properly transcoded MP3. Most audiophile mania is poorly informed at best and astrology at worst. http://abx.digitalfeed.net/
Cymbals always sound like bubbling shit in mp3.
You're going to get a pretty terrible experience with MP3 128kbps, whereas modern variable bit rate schemes can actually be quite decent. Personally I prefer to always go lossless, but for most people on most systems, the difference isn't noticeable. (Moreso the better the system gets, ofc)
