replaced by the LD-S2, one of the first pieces of equipment in the then-new "Elite" lineup. Upgradeability Despite its capabilities, the S1 lacks two features often demanded by LD enthusiasts: a dedicated output for digital audio and an AC-3 output capable of sending out the modulated AC-3/Dolby Digital audio found on most LD releases from the mid and late 1990s. Fortunately, both are fairly easy to add to the player and often technicians that are qualified to recondition the players are also capable of adding the outputs. Subsequent models Later models under the same line include the CLD 2070, 2090, 3090 & 3390. The video of the CLD 2090 was impressive, and rivals the Elite models which were released shortly in the early 90s. Pioneer started the Elite line to separate the mid range players from the higher end players. The CLD 2090 comes with S-video out and optical audio out. In comparison, the video quality even surpasses the late 90s model DVL 909 (LD and DVD player). References External links A page on the CLD-1010 LaserDisc CLD-1010
