I have survived enough products disappearing to not worry such things. I'm pretty much set for life, audio wise, anyway, and can always DIY a power solution for good tunes. I have 3 amp kits worth of parts in my closet, yet. The next best thing cannot possibly be audibly better than where I have been thus far. My bedroom system doesn't even have subs, and I enjoy it as much as anything else. The band has been in the room (or better) with me for decades, regardless.
Once umbrella corporations became commonplace with food and everything else, brand names don't mean the same to me, nor loyalty, for that matter. Not as they once did. How many brand names are we going to really need to rebadge Icepower, ATI, Hypex and Purifi modules into?
