So in the past few months, I added a convolution filter to my speaker system for room correction (frequency response & phase) which significantly improved the sound over the parametric EQ corrections I was using before. And then yesterday, I realized I never added any subsonic filter to the convolution filter and adding that for the subwoofers (and speakers when playing them alone) also dramatically improved the clarity of the sound.
What I realized (even for myself) is that how easy it is for us to start ignoring sonic distortions.
I used to think that I have tuned my stereo system as close to the Focal Utopia headphones via parametric EQ alone but in reality, I have just trained my ears to ignore the bass frequency and phase distortions or the low bass rumbling I’m getting from my subwoofers or speaker woofers that is causing loss of clarity in the higher bass frequencies. Now that I had both fixed, I find that I can hear the difference between Focal Utopia headphones much more than my speakers in terms of these aspects.
The reason why I’m posting this in the Watts Up forum is that I remember seeing lots of posts saying they don’t find Chord DACs special or they don’t hear any improvements from M-Scaler. I used to chalk it to poor hearing or people have such terriblly recorded music sources that their systems need lots of euphonic distortions.
But in reality, I’m more and more convinced that our brain accommodates to all the sonic distortions from most music systems that they are easily capable of ignoring:
1) Noise floor modulation (which sounds very harsh to me and IMHO is what makes digital sound digital)
2) High noise floor (which reduces transparency and soundstage depth)
3) Poor transient accuracy (which is why poor, short-tap-length filters are widely accepted)
4) Harmonic distortions (which can sometimes be euphonic but causes loss of details and transparency)
I think the whole situation is made worse since most of us don’t listen to live unamplified music that often. So it’s easy to forget what undistorted music sounds like.
I think I have mentioned before that I think the reason why Chord DACs are much more popular with the Head-Fi crowd than high-end stereo crowd is because of the lack of additional components (preamp, amp, speakers, subwoofers, room acoustics) distorting the sound. But I sometimes wonder if Chord has already reached the maximum number of people it can reach because it’s hard to come to terms with the fact that our ears are learning to ignore or even prefer distortions.
