Meanwhile, the UK-based Dutton Laboratories, through its Dutton Epoch series, has released 52 four-channel SACDs that feature works by 20th-century British composers. The label also has 32 soul, jazz, rock, and prog titles, all on 4.0 surround SACDs, under its Vocalion series.
“Quad has enjoyed a renaissance, thanks largely to the rise of audiophile-level home cinema systems,” says Dutton Labs label chief Mike Dutton. “I also think that, despite the quad LP and tape cartridge having been killed off by the format war of the latter 70s, there has always been interest in quad/surround sound, mainly because, when done properly, it sounds great. My own interest in quadraphonic sound began during the early 1970s when, in my teens, I acquired a decoder and began buying Quad LPs.
“The classical recordings we make for the Dutton Epoch label are in 4.0 because in 5.1 the center channel makes the front stereo image less wide, and the use of the bass speaker affects the phase/image placement of the bass in the recording when we use a ‘Decca Tree’—a stand with three microphones that capture the basic image. Also, the center speaker is designed for speech in film, really. Many of our classical listeners like a concert-hall approach to recording, so the compromise is 4.0.”
What does the future hold for quad?
“All this is now changing with the coming of Dolby Atmos and 3D recording,” Dutton adds, “which will extend the scope of surround-sound recording in new and exciting ways.”
