I could be wrong , the story that I heard was that Mr. Had wanted a speaker designed to work with his equipment . He later tired of the speaker buisness and sold that part of his empire .
The new owner ran it for a number of years then sold it to a guy that works for Monster cable . He had his family handling the day-to-day operations untill they finally went out of buisness .
I have not owned the 5.3i's but did have the 6.2i's and had pretty good success with an Audio Aero Prima Integrated amp . It is a hybrid with a mossfet output . I also ran a Cayin A88 T tubed integrated with good results as well . Both of these are 40w amps .
While they may not be SET friendly I don't believe they require copious amounts of power either . YMMV.
Good luck .
