ZenErik, "There is no doubt that the W3000ANV sounds lovely and looks pretty, but "reproduces magnificent natural playback" is what we call marketing BS."
Now how would you go about proving the "marketing BS", unless of course you heard the W3000ANV with and without the "Hokkaido Asada cherry heartwood." If I am not mistaken, high quality pianos are made of cherry wood to produce a certain natural desired tone. I happen to have ATH-W1000X headphones modded with ATH-AD2000 drivers, and the AD2000 drivers sound very natural in the W1000X as compared to their sound in the AD2000, at least to these ears! You are entitled to your own opinion though, but I haven't tried different material with my ESW9's either.
