He's not talking about CDs, he's talking about picture disc vinyls, and traditionally those don't sound nearly as good in quality as black vinyl, particularly 180 gram, hell, colored vinyl also have been known to be inferior. I don't know why they keep putting out new Maiden stuff on picture disc though, guess they figure people will mainly use them as collector's items, us audiophiles be damned.
Also, I have a jerry rigged set up for my 100 dollar turntable and it still blows away the sound of a CD, not all that expensive actually.
