For those interested, the eac3to (SSRC) resampling graphs are now online here:

As far as I can see, eac3to belongs into the top group of steep resamplers. It's intentionally not as steep as the original SSRC algorithm, but still belongs to the steepest algorithms in the comparison. However, if you are willing to sacrifice high frequency response and if you don't mind some aliasing artifacts, there are other resamplers which have noticeably less ringing. I've learned that there's not one "best" resampler. Going steeper gives you get better high frequency response, but you buy it with stronger ringing. So the "best" resampling algorithm/parameters depend on the material and also on your taste...
