Remastered 2015 Tusk CD versus 2004 CD

[Nomad7]

Greetings. Super into the Tusk Deluxe set now. I also created stereo tracks from the 5.1 disc and have played "Sara" 418 times according to my iTunes. Love the vocal put up front etc.

My question here for those who know audio etc is what are the differences between the Tusk 2015 remastered version and the 2004 version. I have "Sara" from VBFM in my iTunes library at 700+ plays. I assume that's the same "Sara" from the Tusk 2004 remaster. Is the 2015 remaster better? I can't hear much difference but my ears are aging!
