To all the owners of the 2016 MacBook, how do you find the sound quality of the new MacBook when using headphones? Is it able to drive large headphones? Also, do you hear any hiss or humming especially if you are using it with IEMs? I went to the Apple Store today to check the highest supported sampling rate on the MacBook via the Audio Midi Setup app, and was disappointed to find that it supports only up the 48khz. The recent MacBook Pros all support up to 192khz audio. While the majority of my music collection is CD-quality (44khz), this means the MacBook is not future-proof as it is unable to support hi-res audio.
