What's going on with Shelter Audio (Japan)?

Their presence seems to be disappearing, or at the least receding. MusicDirect shows the flagship Harmony model "No longer available". Needledoctor is no more but they showed it "out of stock". Shelter Japan's website has axed much of the lineup in the past year, including the 9000/7000/5000 models and the Accord (smaller sibling of the Harmony) which had only been introduced in 2014! My email inquiry about re-tips/rebuilds (I have both a Harmony and Accord) to the supposed NA distributor (Axiss Audio) went completely unanswered. I'd hate to think they may be winding down for good, but the superficial signs aren't good. Anyone here know anything?
