I'm changing jobs and with that I move from Windows PC to MacBook Pro, which has implications for my office audio set-up. My ego expects that somebody will remember my quest last year to get this office set-up purchased. I currently have: Network Drive and Local Drive containing FLACs (16-bit/44.1kHz to 24-bit/192Khz) played via Lenovo X240 Laptop connected by USB 3.0 to SMSL M6 DAC connected by RCA cables to M-Audio BX5 active speakers I need to work out the best way to replace the Lenovo ... bit with a MacBook Pro bit. At the moment this consists of: foobar2000 plus foobar2000 WASAPI component connected through SMSL M6 Windows USB Driver to USB 3.0 cable So what do I need to prepare for when I get the MacBook Pro? I have heard about Audirvana, BitPerfect, PureMusic as well as iTunes to play back music. I really don't want anyone managing my library just sending it directly to the DAC. I also believe that the MacBook Pro will output directly to the DAC and I just need to set-up "Audio MIDI Setup". Any help to get the right steps together and reassure me that I'm not up- or downsampling somehow in the process of playing is greatly appreciated.
