Compact disc
Compact disc (CD) is a digital optical disc data storage format that was co-developed by Philips and Sony and released in 1982. The format was originally developed to store and play only sound recordings (CD-DA) but was later adapted for storage of data (CD-ROM). Several other formats were further derived from these, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video Compact Disc (VCD), Super Video Compact Disc (SVCD), Photo CD, PictureCD, CD-i, and Enhanced Music CD. The first commercially available audio CD player, the Sony CDP-101, was released October 1982 in Japan.
Meridian Audio
The company was the first to introduce active loudspeakers (loudspeakers with power amplifiers inside the cabinet) designed for the domestic market, and was the first British company to manufacture a CD player in 1983. The Meridian MCD, launched in 1985, was the first audiophile CD player. In his review of the MCD, audio engineer and "Stereophile" founder J. Gordon Holt wrote, "For the first time, the sound of the best CDs (Telarcs, RealTimes and Sheffields) is truly liquid and transparent, with an effortlessness that I have not previously heard except from the better analog sources... To date, then, this is the best-sounding CD player I've encountered." Meridian also created the first digital surround-sound processor and the first DSP-based digital active loudspeakers.
