-110db is audible if you use some high quality monitor. And dont forget the noise will accumulate during the mixing session, so if you do lot's processing, after mixed the whole session, you may hear the difference.
If you need some analog processing and need D/A or A/D, the resampling may has negative effect if the algorithim is not good, for these, you can check on src.infinitewave.ca. Although the test result varies from what I tested, SRC function in some of the software are really awful. However, as I read in Pro Audio maillist last year, if the coefficient is just 1:2, 1:4, most plug-ins and DAW will work without problem and my test proved the point is correct, so I think if are working on CD medium, you can try upsampling to 176.4KHz and resampling to 88.2KHz during the analog procession if you pay attention to the quality. But upsampling the session only to 88.2KHz and avoid multiple SRC will save a lot of time.
I am going to design an ABX double bind test to see if the improvement is really audible
