So I've revisited the issue about the sibilance I've been having with my AT440MLa. I think I might have exaggerated it a little bit.
I recorded a track from one of my records through my computer's on board line-in jack and decided to compare it with my digital copy of the same song. It turns out that I was playing it too loud and it accentuated the sibilance a lot. The amp portion of my headphone DAC+amp is also quite bright so it had really made for some harsh top ends and sssssibilantssssss
Initially I've recorded the track to ask whether the amount of sibilance is acceptable or not, now I don't think I need to ask anymore. But still here's the download link for the test recording if any of you are interested. Sound quality might not be top notch as the on board sound chip is only capable of 16 bit recording.
Warning: Spoiler! (Click to show)
Are the sibilance levels acceptable for an AT440MLa?
Sounds good to me.
