I assume it is the same for the Go-Pods.
1) Bit-Perfect is equivalent to what has been called “non-oversampling”, “zero-oversampling”, “filterless” etc. This offers the best impulse response but loses high frequency extension. There is no pre- or post-ringing with an impulse and ultrasonic images are minimally suppressed. This filter produces a sound that is highly musical with precise but sometimes a little limited imaging and seems to slightly lack detail and air.
If you go "by the book", so to speak, for digital to analog conversion, Linear Phase, Fast Roll-off would be the choice.
