Won't post any links, they are easy enough to find, but it looks like RSH is circling the drain after a "prolonged illness".
Granted, they haven't been a factor in the audio market in years, but this company once was a Cheap n' Cheerful haven (back in the day, some of their low buck speakers were pretty respectable for the money) and at the dawn of time they sold things like the "Lifetime" tube line and Janszen electrostatic tweeters (!). I remember the one near me when I was a kid had an AR turntable; the manager always had bass, treble and midrange all turned up...
They always had that oddball "doohickey" you needed and they were all over the place.
I worked there for a while late 90's- early 2000's. All they were about by that time was cellphones, and trying to sell one to anybody who came in looking for anything else.
