- In response to Jeff Lo's article about why filter D/A output:
-
- I think the main reason to filter out D/A output is to reduce the RF
- output from the line output. Most DACs use 1st order hold, thus generating
- some ultrasonic garbage. If RF input into preamp/poweramp etc. is too high,
- the amplifier could oscillate and give out a lot of distortion.
