Volcano filters cramping
Could it be that you have enabled HQ mode? When HQ mode is applied, there is indeed a low pass filter that prevents aliasing artifacts from bouncing back into the audible range. When HQ is disabled there should not be a roll-off until 30KHz on a 44.1KHz system, which is way above nyquist.

Hello,
I noticed the filters in volcano cramp at nyquist quite a bit. Has there been any thought to prevent that and get more of an analog response from them in the high end?
