That comment is still true. A K-meter is for signals
that are in a sense the 'end result' you listen to.
For monitoring 'technical' levels in digital audio
the peak digital level is all you need. 

A much more serious failure of Envy24ctl's meters is
that they don't provide any level indication at all.
Where is -10 dB ? or -20 dB ? Except for checking if
a signal is present they are just eye candy.

For me it doesn't matter at all. I/O gains are fixed
and levels are checked either by application software
or by the external equipment (a mixer in my case, the 
sound card is connected as if it were an 8-track). So
in practice I never use Envy24control.
