Hi Dennis and Tim.
Thanks for reading. And thanks for the wonderfull software, Tim.
@dtoss I am glad you asked :-) my setup is:
Speakers: Philharmonic Audio. BMR philharmonitor
Speaker cables: Duelund 12 awg tinned, oiled copper in cotton.
Amp: Densen B-150 xs class a/b
Interconnects: Black Rhodium opera silver, with eichmann silver bullets. To be changed.
DAC: Khadas tone board
Player: Rpi 3b+ with hifiberry digi + transformer hat. Powered by ifi ipower.
I did the power by-pass via the hat modification this weekend. Music on an USB.
The power via the hifiberry digi + helped to get some air between instruments and some of the edge from female voices. But I still miss some of the presence and life like sound I perceived to hear with the wav format. Maybe some details to the instruments emphasising the type. Eg. Crisp overtones from the strings of a double bass, and the natural noise when they slap against the wood.
Disabling software volume ctrl in MPD helps. I thought I heard an improvement in sound when upsampling in SoX. But it could also be that the gear was getting warmed up. I could not detect any improvement with upsampling today.
I would like to try the sound tweaks posted by Edward a year ago in this forum. But I am confused whether to use the debian, tinycore of arc linux. Any advice?
@Tim Curtis The Khadas toneboard should support various formats. Would it possible or even worthwhile to feed the files raw to the dac?
Thanks
Jacob
