No, the DAC is hardware - hardware doesn't "adapt" with use. (Hardware that appears to has software running in it - DACs don't.) The G7 may change with use. I haven't heard of "adaptive sound", but who knows what they added under the hood without telling us?
Thanks! Have not tried the EQ presets yet as I want to keep it neutral but eventually, I might try it if the sound does not improve.
Either that or my ears will adjust to the new G7 DAC sound signature
The DAC does sound good when connected via 3.5mm headphone jack to a Passive pre-amp [Schitt] that is in turn connected to powered Paradigm Active20 monitors.
