I also wonder how much of the CLASP-grasping is generational. How many Gen Y recordinging artists/engineers care about tape given their general lack of exposure (except by those at least a generation or two older than they are). Just a thought.
I imagine that may be part of it. Although plenty of the Gen Y folks are re-discovering Vinyl, so maybe not as much as you might think. Ultimately, it just depends on what types of sound you are trying to achieve as an artist. There are things you can achieve with tape, from a sound quality altering perspective (by taping at different speeds, for instance), that you just cannot achieve at this point in time with digital simulations. I liken it to photography. While digital manipulation is getting really good, most of the high end photoshop plugins still cannot render a really effective representation of a film shot, toned silver-halide print (such as sepia toning or selenium toning process). They can make an interesting look, but if you compare a print of it to the real thing, it still pales in comparison for lots of reasons. At the same time, I believe we are in the beginning of the digital revolution still, not the end. I fully expect it to continue to improve at an amazing pace.
