The cards above the "Gold level" in that table are professional audio
cards with the associated price tag. The Turtle beach is at the top of
the list of "consumer" cards. You do not need 113 dB of dynamic range
for amateur sound card applications (not SDR but TTY programs) so why
would anyone doing TTY spend $2500 on the Lynx Two?
Those cards above the gold line get their performance in these tests
because they are 24 bit sound cards. Most sound card programs doing TTY
(all of them?) open the cards using directX or
MME (not WAVEFORMATEXTENSIBLE) and this limits them to 16 bits. You
then get the same noise floor and dynamic range as the Turtle Beach.
The Turtle beach is not perfect but it is a great buy at its current price.
