here my test and my doubts:
I compared the same album in two different mode:
1-played on my CD player Linn mimik (original CD, the quality is 16/44KHZ)
2-played on raspberry(volumio of course)+hifiberry the same album but ripeed in HD quality (24/88.1KHZ). I used Spenk tool to confirm this is not a fake HD album (ex normal 16/44kkhz ripped ad higher bitrate)
The strange thing is that the CD version is very very better (ok othe cd player is a good piece) but the difference is huge.[/b]
I do another similar test using another original CD and HD track at 24/192khz
so I do a verification: I ripped one CD on flac file at 16/44. Compared FLAC and CD. Result: no big differences
So now, where is the problem ?
HIFIBERRY is not so good at high bitrate ?
Raspberry board is too slow and the interpolation FAST setting cause this lack of quality ?
anyone do the same test ?
