Slightly more rational than what? :)
It's ironic that I've posted the Lavry link myself recently in a similar discussion.
However, there is quite a bit out there explaining why some feel that higher than what may at first appear to be sufficient Nyquist rates can be useful in some circumstances. The explanation is not that Nyquist/Shannon were wrong but many who have made incorrect assumptions about real world converter hardware filtering. As I understand it, in order to overcome these real world limitations within reasonable budgets is where higher sample rates may start to make sense over more expensive filtering hardware etc when ultra low distortion is necessary.
As I've mentioned earlier, I'm no DSP expert so I'm probably the wrong guy to try and explain it all. I'd end up with some BS about imperfect brick wall filters, finite band limiting is impossible and some hand waving and be totally embarrassed but it is a fairly common topic via search.
I believe this linked white paper may start to hit on some of these subjects. I'll try to remember to ask my buddy at work about this stuff and see what he says. It's all very confusing for me.
Whatever the case it's easy to find many search hits suggesting even 96kHz sampled to 44.1 ruins quality even when "perfect" 64 bit algorithms are utilized.
I have not yet tried to verify any of it myself.
