Very helpful, this will allow me to look at the whole process and start with source. I thought I understood compression, but obviously not enough. I was thinking of the Senn HD 598, however for this purchase I needed more portability for traveling and went with the 380. I was thinking of the Sansa Clip+ for another backup MP3. Do you prefer the Sansa over the Sony Walkman?
I don't have any real use with the Clip. My only Digital Audio PLayers to date are a iPod Gen 3 Nano a Zune HD and 2 Hifiman DAPS
Still the Clip+ has been getting positive feed back for ages here. Not sure there is really anything cheaper than it that does all that it can do!
