Yep. I'm fully aware of those "squiggles", and despite somewhat destroyed ears, this disturbs me as listener of recording.
I can adjust to it when editing noise/music on software, as I know it won't be there when final music is ready and stuff is burned on master CDR. But it disturbs me that it IS there until material is out from computer.
For this reason, better speakers won't help in computer listening - it may even damage severely. My current speakers has so detailed and crisp high frequencies, "regular quality" mp3 is pretty much impossible to listen to. While muddy low quality speakers may cloud the shittyness, high fidelity speakers exposes all the flaws.
While some people always conclude that it's just noise what sounds rough and crappy anyways, I tend to strongly disagree and expect highest possible audio quality from noise. If format is able to correct flaws of musical material, it's benefits of it, yet if it increases the flaws, it fails.
Good example is Genocide Organ's latest album. LP sounds about 10 times better than CD. Yes, it is very rough DMM cut. Yes, it adds this layer of distortion on top of just about everything. But just compare CD and LP. Songs like Tamil Eelam or such... What a drastic difference of LP and CD ! While one could complain that LP suffers from lack of fidelity due DMM cut, in this case it basically gives the touch for kind of overly digital multi-effect glitch sound, transforms it to something nasty and warm. Like loudly dubbed tape where format adds little dose of sonic magic in purely mechanical/magnetic/physical process. I would feel kind of sorry for those who'd settle for download, as they'll miss a lot. In same way, in some cases, those who stubbornly worship fidelity of LP in cases where CD is without doubt more suitable, appear as music haters. They worship format, they don't worship the sound/music. So I could merely repeat my previous conclusion: I prefer format what compliments each sound piece. On every level: Sound/presentation/general atmosphere.
