Not that good I guess.īasically, they alter the output in very, very subtle ways that you can’t quite put your finger on but they are doing something underneath the hood for the nuances of the signal. All of this topic is some fairly complex mathematics that just scrambles my mind even though I was pretty good at math back in the day. I don’t know much about Finite Impulse Response vs Infinite Impulse Response to begin to explain any of that. It gets much more in-depth and far beyond me with the impulse response characteristics of each filter (pre-ringing, echo, etc) and the way the each type of filter will affect the phase of the signal. If you want to dig, that’s the matrix x-sabre pro MQA model DAC with an ESS 9038Pro chip. These aren’t labeled on this chart and it’s late so which one is which is up in the air. Fast roll off and slow roll off become more obvious when you see charts like this. Most obvious is that the filters impact where and how the frequency rolls off at the upper extreme around the Nyquist frequency. including me.īut I’ll try since you still have no replies. It’s a really in depth topic that most aren’t really equipped to explain.
