If I'm feeling charitable I could imagine they're perceiving interference differences because the DAC is internal integrated junk.
I've had thinkpads in the past that would output varying degrees of noise on the analog line+headphone outputs. It was highly dependent on what the CPU was doing, how much data it was moving around. It was kind of fun as a sort of audible system instrumentation while developing/testing software. The more optimal I'd get things, the higher pitched the noise became.
But no "audiophile" should be using such cheesy analog output from a computer... At least get some S/PDIF off to the fancy preamp.

- pengaru 4y agoIf your external DAC is on USB powered by the PC's USB port, your external DAC is external in name only...
- reportgunner 4y agoI don't know about other laptops but I personally experienced a latent issue with all lenovo laptops (thinkpad & ideapad) where there is a short between the keyboard and the audio card - you could hear very faint static with headphones plugged in when there was no audio playing and I could even hear the static change when I scrolled my mouse - possibly because of how closely packed everything is.
