Nice work. Unfortunately, shops in Japan change so often that guides don't last long. It's really a nightmare. Also, most foreigners don't realise that a lot of shops are not on the ground floor, or have multiple floors, so miss out on a lot of good stuff.
Dynamic Audio used to have a dedicated headphone shop, around the corner to this store. It's a great shame they've abolished it in favour of other audio gear. There was even English-speaking staff.
