Yes I used the same speakers for the comparison, and yes the copy sounds less dynamic than the original.
Yes, compressing to flac was really unnecessary. I don't remember why I did that =S
I have had playback problems (skipping) with other cd-r when burning with this burner, but those TY works fine so far. I don't know how this writer is, it's a LG HL-DT-ST DVDRAM GSA-T20N.
How do I check if the original cd is CDDA compatible 16bit, 44.1 kHz stereo audio?
I have tried to convince myself this morning that i'm just imagining, but I'm not. I remember using EAC "paranoid" when copying because for some reason I couldn't get all the tracks to copy with 100% track quality without it. I copied some of the files, uncompressed, again today (without paranoid) and burned them with 16x and I think it sounds more like the original now. But if the write speed doesn't matter then I must be imagining.
Sorry for my English =)
