Sound Quality on Allo Boss Rev.1.2 between Rune / Volumio

Hi all,

after endless Hours of testing with resampling,
my final opinion is as follows.

According source Material is not better than 16/44.1
resampling to 24/96 adds more responsive Bass
but at the cost of less detailed and softer high Tone.
Stereo Width shrinks a little on some Material, others seem unaffected.
Which might be the reasoned in Phase Effects trough the Main Mix, but that's only a guess.
Resampling higher than 24/96 had no greater effect.
If source was 24/96 or better, resampling adds nothing
might even get worse.

All tests been done on FLAC with same Samplerate as Original CD,
Pi3, Allo Boss DAC, direct link to M-Audio M3-8 Speakers, Studio.

With SoxR active in mpd.conf, Pi reacts -or did not react any more- strange after
uptime of more than 48hours; and had to be rebooted.
Sometimes an MPD restart helped, but reloading the config was not possible.
Anyhow, didn't focus on that issue rather than hearing

kind Regards,
Phil.

Hello PhilHill,
Many thanks for posting your findings, very time consuming and difficult to do objectively. But this is what it is all about, the technology is interesting but it’s the sound that counts. While you can assume many things, only when someone actually does it do you get real results.
