HN – Ask HN: Is onboard audio still good enough compared to dedicated Sound Cards?

Recently, I upgraded my outdated PC to a Z890 motherboard, primarily because it was significantly discounted compared to AMD alternatives. After the upgrade, I noticed that the Realtek onboard audio doesn't sound as good as my previous configuration, which used a Recon3D sound card. Although I haven't conducted any scientific tests, the difference in sound quality is quite apparent to me.

I'm reaching out to understand the technical reasons behind this perception. Do dedicated sound cards offer tangible audio quality improvements over modern onboard solutions like Realtek? Specifically, I'm interested in aspects such as DAC quality, component shielding, and feature sets that might contribute to a superior listening experience.

Additionally, how much of this difference is rooted in theoretical hardware advantages versus user experience factors? Any insights or experiences from device engineers and audio enthusiasts would be greatly appreciated!
