@jasonbourne52 - There’s a review by Goldensound for the Denafrips Ares II that includes measurements that demonstrate the oversampling slow filter having some very unexpected and the fast filter appearing to measuring as expected. The recommendation was to not use the slow filter. I don’t know if the specific unit being reviewed had an issue, but it’s very interesting that the nearly unanimous consensus is that the DAC sounds the best using the slow filter. I have not spent a lot of time comparing the two, but switched to the fast filter based on the review and recently went back to the slow filter and also preferred it’s sound.
Experiences like this challenge my natural tendency to believe that something that measures better should sound better. I’m starting to believe that measurements have little meaning because it’s become unquestionably clear that individual preferences simply do not align with measurements.
Objectivists accuse subjectivists of being subject to expectation bias, placebo effect, etc. Is it possible that the primary factor in objectivists preferring the sound of equipment that they believe to be superior based on measurements is a result of the same factors?
