Spotify sounding better than FLAC?!

Posted by: audiokid on 12 August 2012

I may be going crazy but playing tracks on spotify premium seems to sound better than playing the FLAC equivalent on iTunes with BitPerfect. I have optimised my BitPerfect settings as per the manual. Both options I have streamed from Mac mini into the Naim DAC - wireworld optical - SN

Where am I going wrong? I also tried Fidelia which seems to sound the same as iTunes with BitPerfect.

I was hoping to try the NDX to see if it helps, and swap out the DAC for the NDX. Others mentioned that it wouldn't sound as good as the Mac mini / DAC route.
