Well I agree the vocals are up front, I certainly wouldn't call it a bad recording. But if you thought the CD was unlistenable, I wouldn't buy the DL.
The "serious filtering" is a typical comment by people who take 5 seconds to make a spectrum plot with Audacity. Do such posters have any idea what they are looking at? Do they hear anything when they listen that sounds like "serious filtering" or would they know it if they heard it? Doubtful.
