	Do you require a metering device on your turntable or cassette
	deck that displays tracking error, distortion etc.?  (I agree that
	it is extremely useful to know these things, but usually your
	ear tells you something is wrong then you check out the equipment.
	Is there any reason why a CD player should have a capability that 
	most analog devices lack?)

Is there any reason that a CD player should produce sound better than
most analog devices are capable of?     :-)

Turn the question around.  Is there any reason that a turntable or cassette
deck should contain equipment for monitoring tracking error or distortion?
I'd say yes, but that it would be too expensive to include to be worthwhile.
But adding a LED that indicated that interpolation was taking place on
a CD player should be very cheap since the circuitry already knows that
it is taking place, so there is no reason NOT to do it.

If I owned a CD player, I'd like to know that the disc I bought is defective,
even if I can't immediately hear the problem (maybe I'm not listening
critically right now).  On the other hand, if I could hear something that
sounded strange, I'd like to know that it was due to a bad disc and not
my CD player.
