Digital Oversampling Filters
Your Little Ego offers a choice of three different digital
interpolation filters, each of which sounds subtly different.
To select a digital filter, press the Filter Select Switch once.
The first LED will blink, and one or more of the LEDs above
it will light steady blue - indicating which filter is currently
selected. While the first LED is still blinking, press the Filter
Select Switch repeatedly to cycle through the available
filters. Within a few seconds after you stop pressing the
button, your Little Ego will switch to the new filter, and
resume normal operation. You will hear a slight period of
silence when the filter switch occurs.
The
Symmetrical filter (F1) is a classical design which
combines equal amounts of pre-ringing and post-ringing.
This is the filter most commonly used by other DACs.
The
Asymmetrical Low filter (F2) has virtually no pre-ringing,
but several cycles of post-ringing. Many listeners find this
combination to sound more natural, while still preserving
the liveliness of your music.
The
Asymmetrical High filter (F3) has virtually no pre-ringing,
and very little post-ringing. Listeners tend to describe
this filter as sounding very mellow, but possibly more flat
sounding than F2 with some program material.
