As a perfectionist you should be rejecting the notion of using a design beyond its limits. I too once was fascinated by the high contrast images that come out of cameras which have the AA filter removed. But
- this only works if the input signal is bandwidth limited such as to not exceed the sensor's resolution and
- in the latter case you can achieve the same contrast with capture sharpening. Capture sharpening is not cheating, it is an appropriate step.
- If the input signal (scene) is not sufficiently bandwidth limited, you get nasty moiré which is a lot harder to remove than AA-blur. Did you remove the AA filter from your CD player? This only works if the rest of your chain (or your ears) effectively acts like a replacement filter. You don't want to listen to a digital recording where the sampling wasn't done with an appropriate bandwidth filter. Otherwise you'll be hearing things that were never part of the original sound (you'll hear mirror images from frequencies beyond the Nyquist frequency). This would sound terrible but yet you are asking for something very similar for your camera.

What if I like LR which doesn't offer moiré removal? I don't know C1Pro, but as I said AA-blur removal is an easy and natural step, whereas moiré removal is a challenge in damage repair.

Well, if prints are this fuzzy, they hardly can be used as an argument in a discussion about top image resolution, can they?

I suspect you are looking at them the wrong way. Either you are pixel-peeping without normalising different camera images to the same resolution or you are not applying the appropriate capture sharpening (which will differ for each camera).
I may be proven wrong, but I'd be very surprised if we -- some time later -- won't be convinced that the K-5's images provide excellent detail.
