Shiitaki, I actually do use error correction. It's awesome. I can burn a whole cd in a half hour! lol
Soundgasm, I guess I could describe the sound difference with cd as a fatter, fuller sound with a very distinct sense of presence. Coming from the NAS it just seems lifeless and thin. The bass is actually a bit more textured (which I like) coming from the NAS. CD not so much. While I suffer a lack of the audio lingo as well I think what I used to describe it should suffice.
And I have done an a/b between these. Both with a slightly different and distinct flavor. It is quite evident. And that is the part that really bothers me. Everyone is so anti-cd now and claiming insane results with digital files and I've done everything and taken every step to ensuring I'm doing it correctly with no besting of the cd. From a PS3 no less!
So either everyone is caught up in the convenience of going digital and trying to justify it by saying its better or I have some serious equipment issues. I might not have high-end gear but come on, at nearly $7k retail it isn't exactly the most basic entry system either.
