signal more like the maximum you’d get
on a music disc (–20dB), distortion reduced
even further, so that just a single third har-
monic distortion component is visible, at a
level of –119dB (0.0001%). This is excellent
performance.
Very low-level distortion performance
was also excellent. Using an undithered testplaying CDs (0.32° at 20kHz) than when
converting 24-bit/48kHz signals (around
1.1° at 20kHz, see Graph 7).
The square wave and impulse responses
(pictured) show that Lindemann is using
software-implemented filtering in order to
reduce the level of pre-ringing, which it’s
done successfully, though some pre-ringing
is still visible, and the post-ringing remainsat the levels I’d expect from commercially-
available oversampling devices.
Distortion from CD was very low, with
the tabulated figure at 0dB coming in at just
0.026%. The distortion output spectrum for
this is shown in Graph 1, and you can see
second and third harmonic components at
–102dB (0.0007%), and a fourth at around
–108dB (0.0003%). All others are more
