Audio performance: listening impressions
The iPodHD delivers a neutral, detailed presentation with substantial dynamic range. Low frequencies are controlled and textured, mids are clear and forward without being aggressive, and highs remain extended but smooth. The balanced output provides notable improvement in soundstage width and channel separation for high-end headphones.
Practical notes:
- Use balanced output for the cleanest, most powerful drive.
- Enable the appropriate digital filter when preferring a warmer or more analytical sound.
- For DSD playback, ensure correct DoP settings if using third-party DACs.
