Sorry Boz, I thought the company was big enough but they did peak many years ago.
They specialize in high quality musical reissues from the master tape on 24kt gold discs or boner inducing heavy vinyl. Sometimes it’s hype and other times it’s a big improvement. They started off in the '70s making half-speed mastered vinyl of popular albums like Dark Side of the Moon and The Beatles catalog on special vinyl. They moved to CD and went gold with the Ultradisc, and made the Ultradisc II in the '90s with the Gain system, then developed a similar system for vinyl after shutting down after while. Check on their history page on that website.
