Spectral products blend high technology with hand craftsmanship of an incomparable standard. The immense care taken in their manufacture is an integral outcome of the technological vision that inspires them. Spectral’s style of wide bandwidth, super-fast circuit design requires the finest materials and components, extremely close tolerances, and perfectionist standards of soldering, wire-harnessing, welding, finishing and all the other operations that go into manufacturing and assembly. Design engineers everywhere are constrained not only by the limits of the imaginations and the laws of physics, but by what is practically feasible in production. The Spectral design team enjoys the freedom of being far less constrained than most. Our military – and NASA – certified production technicians, representing decades of cumulative experience in Silicon Valley industry, are the most dedicated and skilled in the audio field today. Working unhurriedly on very limited production runs, they welcome the complex challenges posed for them by Spectral’s innovative product designs.
Purchased parts and components must also meet the same exacting criteria as our in-house production. Spectral searches the world for premium quality suppliers, routinely having parts custom made to our designs and specifications. We carefully screen and hand match components and devices, skimming the créme de la créme for use in our products. Incoming inspections, production quality control and final burn-in and testing are rigorously performed to merciless standards. Every Spectral product that leaves our premises must first pass a personal listening test by Spectral’s president and founder. The goal: that every Spectral unit perform as well as the best of its type we have ever produced.
Some might question whether such fanatical devotion to quality is really worth the effort. Spectral has been described as building “museum-quality” pieces. Our view is that recordings and playback systems are the museum of our musical heritage. It is a boon to all that the contents of this museum are accessible to us in our own homes. And it is our privilege at Spectral to play a role in making them available at the highest possible level of reproduction.
