Am I too subjective or do others also hear that Amazon's player sound considerably louder with more dynamics than I Tunes? I am referring to my downloads
Of CD's into I Tunes knowing the different formats of AAC and MP3 but on playback seems to me that both are fine with I Tunes more warm but Cloud more
spacious and louder....would value other opinions.....

While I don't listen to those services, I'd imagine this is a compression thing. Seeing as you feel that the ITunes sounds more "warmer" that one could be the service with the lower bitrate. Also remember that just because a song may sound louder on one service than another, it doesn't mean it has better audio quality.

Yes that makes sense, did not think of that.

I guess the source stays the same but the taking over the library by Cloud and then it's reprocessing alters it.....especially in it's different format.

Counterituitively if a recording has been compressed to increase average levels (so it is louder) by definition it has less dynamics (difference between average and peaks). At least up to a point dynamic compression can sound more exciting but because what compression does is lower peak levels (so you can or need to increase average levels w make up gain) but the compressed version is always by definition less dynamic
