When Richard Schram founded Parasound in 1981, he combined experience in retail, original equipment manufacturing, consulting, in addition to friendships with some of the pioneers of a burgeoning high-end audio world.
The legendary circuit designer John Curl was one of those early associations, the result of which is that his name adorns the faceplate of a number of Parasound’s most esteemed creations.
As Schram has explained: “When we develop a new product we take the carpenter's adage "measure twice, cut once" to the extreme. Each new model is tested, improved and re-tested under worst-case conditions. It comes to market only when it is a finished product that's ready to stand the test of time. In fact, we don't really know how long our amplifiers last because people write to thank us because the Parasound amp they purchased in the mid-'80s still works perfectly decades later.”
Below are a sampling of products from Parasound’s award-winning Halo line.
