Please note: I despise vinyl due to its inherent flaws, but accept the current situation of the formats. Due to this it is extremely likely I will be purchasing a turntable within the near future.
There is no [or should be no] question that CDs are technically superior to vinyl and have potential for higher sound quality. Ironically, this technical superiority hold CDs current downfall - the ability to increase compression has led to the loudness wars. These 'wars' are not physically possible to the same extent on vinyl because of limitations in the technology. Due to this current issue with CDs and vinyl's 'immunity' to this problem is why vinyl, can and in many cases does, sound better [more lifelike] than CDs. Of course, for the previous statement to be true quality gear must be used along with a well kept album.
Of course there are still high quality recordings being released on CDs, but this practice seems to be falling out of favor in the mainstream being forced to 'audiophile' companies, sadly.
