It is from a desktop PC.
Sorry about the lack of description, creative labels it as a 600ohm capable headphone amp to differentiate from the on-board not being able to power higher impedance headphones. The input impedance I believe is about 22ohm. It uses the same built-in amp as the soundblaster Z, the Maxim MAX97220A. The power is going to be much less than the Magni, but is it enough for a 32ohm headphone?
These are the specs on the chip they use for the amp:
- Output Power 125mW into 32Ω with a 5V Supply
