All other products have been discontinued and are considered "legacy." What is considered "legacy" today was cutting-edge technology not so long ago, and what is cutting-edge technology today will certainly become legacy tomorrow. However, this isn't really a problem if you own one of the listed products or are looking for one on the used market. The quality of our products is so sophisticated that you can enjoy music with them wonderfully. Of course, "better" is always the enemy of "good," and therefore I never let up in my efforts to continually push the boundaries.
