    The THETA digital signal processor is an outboard D/A converter to
be used with CD players having digital output capabilities.  This $2000
box uses a couple of 56001's to interpolate 7 more points in between the
normal 44.1kHz sampled data on the CD.  When used with a stable CD transport
system, this box, and others like it (e.g. Wadia, Meridian), is supposed
to give a smoother, more realistic, less strident, less 'digital' sounding
analog signal (according to review in Stereophile magazine 8/90.)
