Burning a CD doesn’t automatically reduce quality—it depends on what format you’re burning and how you burn it. If you’re using high-quality source files (like WAV) and burning in audio CD format the sound should be the same. However if you’re converting MP3s or using low-bitrate files or burning too fast (like 48x) you might hear a drop in quality or get playback issues. Stick to slow burn speeds (8x–16x) for the best results.
