Hi
I think "Bass Lift" is not a good description of this switch. It covers quite a wide range
I have this switch on my StageDAC and I am just guessing it is the same on the Daccord.
On the StageDAC it raises the gain on frequencies below 2khz.
Here is the relevant section of the StageDAC manual:
Tonal balance
Psychoacoustic studies have shown that our sense of direction is mainly determined by the sonic components with frequencies upto 2 kHz. To keep the sonic signals as much as possible in their originial state the crossfeed filter does not effect signal components above this frequency.
In headphone mode signals that are no longer present in one channel only but are now more evenly distributed over both channels will be less isolated and become a more integrated part of the soundstage. They no longer stand out and this may feel as if the energy in the frequency range below 2 kHz is slightly reduced. This can be compensated by the first switch to the front right side of the STAGEDAC. In its lower position no frequency corrections are made but in its middle and in its upper position frequencies below 2 kHz are slightly elevated to correct the tonal balance.
So by Bass Lift, that means it decreases the amount of bass, due to the crossfeed having a side-effect of increasing it? If so that is interesting, in comparing to the Headroom amp/dacs with crossfeed; which I think are just the opposite, in that they have a switch that decreases the treble due the their crossfeed's side-effect of increasing the higher frequencies?
