When taping a CD, you want to be able to record the 90dB
dynamic range that CD's can theoretically produce (I say theoretically because
most music recorded on the CD's doesn't take advantage of this).  Therefore,
if you want to tape a CD, you want the best NR system available and that's dbx.
A good tape deck with dbx NR can give you close to the 90dB dynamic range of
a CD, since dbx can provide up to 50dB of noise reduction.  The best Dolby C
can do is 20dB and Dolby B can only provide 10dB.
