I would really like to see objective test results for the different audio software options for both Windows and MacOS (Intel based) computers. JRiver, foobar 2000, iTunes, Windows media player, Audionirvana+, others? I imagine this might be complicated and the results may be dependent on the controlled test platform components (cable, computer hardware, audio drivers, etc.). I don’t know. Personally, I am interested in results for the USB computer to DAC interface. I would think there would be great interest in this data. I’ve read that iTunes doesn’t have great sound quality but haven’t seen objective data that supports that conclusion. I am currently using the TEAC HR Audio Player software with my MacBook Pro (late 2016) and TEAC NT-505 with the CG-10M clock. I am thinking of moving to JRiver.
