The best way to describe the sound of my (former, sniff) 300X-SE is "open, neutral, unimpeded".
I think this is due to the no-feedback design.
Other equipment I've owned seemed to be holding back the music -"maybe if I just turn it up a little more...".
Honestly, the BAT just gives you the music -period.
It inspires confidence that you are hearing everything that is on the disk.
