I have tried a variety of settings, i.e., ASIO vs wasapi, and have been unable to eliminate high frequency losses through Dirac Live Processor (lower curves), compare with straight through to a topping E30. Both sets of curves were collected with REW using a USB connection to a topping E30, with umik-1 and the manufacturer's correction file. Please note that I applied at 300 Hz cut-off to the filter. Psychoacoustic filtering. This difference in FR is audible to me. While I realize that these results suggest I can do without Dirac, which is what I am doing, I did pay a pretty penny for the software to correct my KEF Q350 speakers (I am now using LS50 meta speakers) and this behavior appears to be a significant problem. I overlooked this until now because I did not make measurements outside Dirac.
My specific questions are:
(1) Has anyone else seen this kind of thing?
(2) What might I be doing wrong that could account for this?
