Funny that you bring this up today; I was just looking at some Chinese built amplifier yesterday that mixed wood and metal the way Unison, Pathos and other manufacturers have done and thinking just how stupid it looks. I do like a well implemented mix of wood and metal, but I cannot think of any audio applications where I've seen it done well. I think it can be quite stunning when done well, but the audio manufacturers seem to be throwing it in as a design novelty rather than something that is well-integrated and thought out as an integral part of a design. Also, it seems like the trend is to make the wood look as if it were a blob of Play-Doh™, all rounded and amorphous looking. Personally I don't care as much how components look as I do how they sound, but to answer your question, well, I guess I already did!
