Not at all. You would hear it in slower passages as well where the O2 despite it's speed advantage loses out on resolving that information. He's talking about stuff you would hear regardless of speed, for example ambient cues and subtle dynamics in recordings that have that information. None of my metal is well enough recorded to portray that information. I'd need some obscure Scandinavian symphonic metal band remastered by LFF most likely. Could be you are fine w/ the ODAC/O2 combo for your content which is a good thing and huge money saver.
I seriously think the CD player is doing weird stuff man. This is why I got a separate ODAC in it's own box among other reasons.
