Stand alone CD Player vs. BD/DVD Player

[Ryu77]

I've just begun researching the merits of having a dedicated CD Player. I've heard it mentioned many times that a dedicated CD Player is superior for music CD playback...

As I have become interested in higher quality audio equipment, the why to the above question has interested me.

I have learnt that it is to do with the laser assembly and the amount of error etc.. However, I can't help but question this theory. Isn't data simply data? Meaning as long as those 1's and 0's get there, they can't be any different to the original. For example if I copy a CD full of photo's and then copy the copy over and over (as long as I keep the disc clean), wouldn't the photo's still look the same from the original? How does the laser in my PC drive affect this? What resides on a CD is digital audio... So if my BD Player bitstreams this information to my AVR, what makes that data any worse off than a dedicated CD Player doing so?

I could understand a dedicated CD Player sounding better due to its superior DAC's and pre-amp stage but if I am bitstreaming, doesn't that mean my AVR is taking care of all this?

I guess my real question is, would I benefit from a dedicated CD Player? If so, why?

I do want the absolute best quality music reproduction possible.
