INTEGRATED AMPLIFIER
Production start: 1995
The CSA8, CSA18 and CSA28 was offsprings of the original CSA14 from 1993.
The CSA28 is exactly like the CSA14 with the add on of remote control. As a special feature, the remote control digital receiver circuitry are completely shut down, when selecting the inputs manually.
The CSA18 was like the CSA14. Hovewer, the duble triode tubes in the CSA14 power amp. inputstage was here replaced with the exelent low-noice Toshiba audio N-Fets type 2sk147 (4ps.)
The CSA8 was like the CSA18. Hovewer, omitting the RIAA section.
About CSA14:
During the 1990s a series of hybrid amplifiers named “Copland Synetic Ampliers” in short “CSA” was introduced to the market. They were all employing the Copland CSA hybird circuitry design originally developed by Copland in 1980s and put into work for the first time in the CSA14 integrated amplifier launched in 1993. The CSA circuitry employs one or two dual triodes in a differential input stage direct coupled to a solid stage class A Cascode Output.
