Arny;

I downloaded Audio Rightmark and started playing. I have
seen results from it posted before but never bothered to
look into what program was generating them.

Thought you might be interested in my findings:

I am.

From the manufacturer's specs my Twintrak's D/A has the
best dynamic range at 111db so I decided to use it to
test the Flying Cow and the A/D card in the TwinTrak.

I tested the Cow First. M-Audio Lists the Dynamic range
as 102db in the docs. I connected it with balanced 3
foot 1/4" cables to the Twintrak and came up with 106.1
and 106.0.

Not bad.

I then tested the AD card in the Twintrak which is 110 in
the documentation and it came up as 107.8 both times in
my tests.

Again, not bad.

Makes one consider the "don't let the numbers fool you"
advice we've all once been told.

Variations like this are meaningless, given that they are both better than
100 dB.

You get extra points for noticing signfiicant differences in the shapes of
the noise floors. There probably aren't any.

Remember, it is very rare to make a recording with more than 75 dB dynamic
range.

A converter with 100 dB dynamic range contributes far less than 1 dB to 75
dB dynamic range - probably a few tenths.

Bottom line, you've got more important things to worry about. ;-)
