 Recently, several relatively inexpensive sound cards supporting playback
 rates of up to 192 kHz (new DVD audio standard) appeared on the market:
 Audiotrak Prodigy 192 : <a  href=""; 
 SoundBlaster Audigy 2 : <a  
 A suitable amplifier would be the TEAC A-H300 stereo amplifier. Its frequency
 range goes up to 80 kHz: <a  href="";

 and "Stereo Amplifier A-H300"). If you need a more compact and portable
 device, the Avisoft Bioacoustics ultrasound amplifier would be a better
 choice. That device is powered either by a 5 V or 12 ...36 V DC power
 source and has an integrated over-modulation (clipping) indicator in order
 to prevent distortion. Detailed specifications will be available at in a few days.
 An appropriate dynamic speaker that covers the frequency range from 1 to 70
 kHz is also available from Avisoft Bioacoustics. It is compact
 (80*120*65mm), rugged (aluminium housing and SPEAKON connector) and can
 produce high sound levels. In fact, the frequency range goes beyond 70 kHz,
 but the sound levels at these frequencies will be lower. See also
