Audio Quality of High-End Portable Players

csglinux testing setup

Testing setup of headfi member csglinux.

 

Thanks to csglinux we have df-measurements of these high quality portable players:

The list is expanding, it's limited only by the good will of the contributor and reliability of his RME Babyface Pro. The latter has better specs than SE recorder, so these df-measurements can't be just added to the portable players page [the research needed]. But we can compare them separately below. The one-page manual "How to read df-slides" is here → http://soundexpert.org/portable-players#howtoreaddfslides

Df-slides below are sorted by histogram median. Top df-slides represent portable players with higher playback fidelity.
