I decided to forgo basic nutrition for a few weeks and upgraded to an RME Babyface. Very impressed with the sound so far. In fact I wasn't expecting it to sound that much different to my old Fast Track....lol.....it sure does though.
 
First thing on my mind - does this mean my original ARC2 measurements will be slightly off because of the difference in sound? Is it worth redoing them? Luckily I was too lazy to remove the little pieces of tape I stuck on the floor to mark out the positions...so it's not that much of a big deal if I have to 

Should that make a difference? Good question. I genuinely don't know

I haven't lived with the Babyface long enough to make any kind of definitive statement about the sound other than it sounds better - more focused, more open with sharper sounding transients. But do kick drums sound a little heavier through it? Maybe - I'm also open to that being a placebo effect though. I read reviews of some interfaces and hear people say things about the highs and the lows....wish I could be bothered to rig up both interfaces for an A/B test....

I love my UFX, but did it make a "huge" difference?
I would think/hope more so on recorded tracks; so a cumulative effect.
A few guitar tracks and vocals like I do, probably not as big; but "Total Mix" is worth the price of admission.
I think I would recalibrate, probably just because I can.
Enjoy!

Yeah think I'll pick a nice free rainy afternoon and do it...

I hate these posts.  The only way I can know for sure if an audio interface upgrade is worth it or not, is to spend some nutrition money, and find out.  The ARC system doesn't seem as costly as a RME upgrade, so that's probably first.

Dang these forums.

ARC is going to make by far and away the most difference. I can barely stand to listen to anything now unless it's through ARC, including videos. 

I wouldn't expect the interface to make any difference in terms of room compensation. Changing the microphone positions an inch or two from the previous measurement will have a far greater impact.

I guess in retrospect it was a stupid question, since it was the interface I changed, not the room or the monitors! My brain is running on fumes....

But isn't the interface in the signal chain?...both in and out.  However, I wouldn't think it'd make that much difference...no more than your RME upgrade  :-D
