Does HiFiBerry have an amplifier that is compatible with the DAC 2 Pro that is capable of playing ultrasound (up to ~60kHz). It appears that all of the amplifiers offered only go up to 20kHz. Is there a way to extend this range?
If HiFiBerry does not offer such an amp, is there one you would suggest?
Thank you!
You would need an amplifier specifically designed for this. As Class-D amplifiers use output filtering to filter frequencies outside the audible range, you probably need to look for an "old" Class-AB design. Probably many audio amplifiers won't work well for this. Unfortunately I don' know a specific amplifier that I could recommend.
