Audio-GD Reports:
- “The built-in HDMI-IIS input can connect to source devices with a compatible HDMI-IIS output.”
- “The HDMI input signal rejects jitter, resynchronizes the clock and data, and regenerates an accurate clock signal, significantly improving the sound quality of connected sources, especially low-end and mid-range devices.”
- “The source’s HDMI output must match the diagram below, and the MCLK signal should be lower than 40MHz (most sources use a 24.576MHz clock, which is compatible with the DI-25HE HDMI input).”
- “We tested the DI-2014 (a 10-year-old device), a $300 CD player, and other sources connected to the DI-25HE. The sound quality improved noticeably, nearly matching the DI-25HE when directly connected to a MacBook Pro
