IMHO I think before sending review units, or starting review tours, it'd be better for the Aroma company to expand the availability/reachability of their products to many more distributors. Because in my experience, they are very hard to find. There are only two places I've found to sell them; Fujiya-Avic, and e-Earphone in Japan. Perhaps it is the company's priority to serve the local market, so I cannot say much for them to expand abroad. But I think many people would be interested. I've heard and was pretty impressed by their more affordable Witch Girl S, and Pro. Overall sound quality is very good. For the dynamic driver, it reaches quite deep, and sounds very satisfying. The build/design also looks very cool.
