Corrections needed. I compared the Kipsch ear plugs to the Grado SR80s and could easily hear a drastic difference in quality. That happened.
Regarding desktop (not laptop) MB chipset (commonly available Realtek ALC889) being "cheapo," here is something objective about it.
~High performance DACs with 108dB signal-to-noise ratio (A-weighting)
~Ten DAC channels support 16/20/24-bit PCM format for 7.1 sound playback, plus 2 channels of concurrent independent stereo sound output (multiple streaming) through the front panel output
~Three stereo ADCs support 16/20/24-bit PCM format, multiple stereo recording
~All DACs supports 44.1k/48k/88.2k/96k/176.4k/192kHz sample rate
~All ADCs supports 44.1k/48k/88.2k/96k/176.4k/192kHz sample rate
~Primary 16/20/24-bit SPDIF-OUT supports 32k/44.1k/48k/88.2k/96k/192kHz sample rate
~Secondary 16/20/24-bit SPDIF-OUT supports 32k/44.1k/48k/88.2k/96k/192kHz sample rate
16/20/24-bit SPDIF-IN supports 32k/44.1k/48k/96k/192kHz sample rate
~All analog jacks (port-A to port-G) are stereo input and output re-tasking
Port-A/B/C/D/E/F built in headphone amplifiers
We already did the hearing comparison. The result was my main point above. We listened to many well recorded classical CDs and used two Grado SR80s for instant comparison. There was no audible difference - to our ears.
