> I would be happy to get some suggestions for ultrasound (rat range, i.e. up to about 70-80 kHz) computer playback setup: D/A (soundcard), amplifier, loudspeaker. Should do well as a "soundcard" / converter. I would recommend electrostatics for your transducers - most dynamic tweeters are only reliable up to about 40 kHz or so. The Sennheiser electrostatic headphones are measured to around 60 kHz. You might find a ribbon tweeter that goes up there, but again, get the measurements. Piezo's might be an option, but they typically exhibit a lot of distortion characteristics.
