Have some time today to organize some test. Recorded a 24bit 192khz Flac song on my PC (computer accepts upto 24/192 file thru built in Realtek Audio Codec) with Audacity. Screen grabbed its spectrograph on first 6 sec. of song. Three groups of equal/similar spectrographs. Highest Group: Built in LG Music Player, Player Pro w/o DSP, Black Player EX, and Pulsar Middle Group: UAPP, NeutronMP. Kamerton, Player Pro w/ DSP, Poweramp Lowest Group: Hiby, Google Player, Aimp, Onkyo, JetAudio Plus Will retry with DSD later. Just crude experimentation on behavior of various players on V20. Don't know how to interpret the spectrograph. Believe that having more/higher spikes means higher resulution.
