 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  
 Note that both of these sound cards are playback-only at 192kHz. They 
 are both limited to a 96kHz recording sample rate(per the specifications 
 I found via the above links), and are bandwidth limited to ~46kHz -3dB 
 rating for recording. There are a number of audio cards that use 
 brickwall filtering to limit high frequency response before the Nyquist 
 cutoff is reached, so be sure to read the specs carefully.<br>
