Need some feedback TO PROGRESS.....SM7b / JCM 2000 / Steven Slate drums

Another Quick question for everyone.....I'm Running an M-Audio Delta 44 as my audio interface
I'm Looking to upgrade to a RME 400 or 800 fireface
How much will this increase my quality???
I'm assuming quite a bit right????
 
what direction exactly is that bender? i will give the track a listen when i get home......thanks dude
Do you think i pushed the Volume way to much?

I pulled the gtr body out front more and added a bit of bottom and air and hopefully it feels a bit deeper.

no opinion on the level, other than it's hot so FYI I lowered it to give me room to work.
