I have a Lexicon CP-3, a sound processor/pre amp. It runs a couple of Adcom amplifiers, GFA 555 II and a 5 channel Adcom whose number escapes me right now. The CP-3 is 1992 vintage which means it does not have the newer technology like Dolby Digital Surround or DTS. It does have Dolby Surround. Will there be much reason to hang on to the Lexicon anymore? I currently use it simply as a pre amp for the Adcom 555 II and run two speakers. If the Lexicon is pretty much outdated, would there be a way to continue to use the Adcom amps in a surround sound enviroment? Could I take for example a Marantz, Pioneer AVR etc., and use just the pre amp section and utilize the power of the Adcom's or is it just really unnecessary? Thanks in advance, Rat...
