Brief listening notes on the latest revision of WES:

At first, the most striking feel is its realistic sound. Dense high-resolution packs much of the detail. It is tonally balanced thorughout entire audio frequency range. There is no noticeticable addictive to tremble and bass, and the mid range is warm and full. The SR-009 certainly is the best headphone Stax made to date.
