I just purchased a new Alpine CDA-9887 to upgrade my daily commute car. It'll be matching with McIntosh amplification, Eclipse component mains and in-door Tang Band subs. My main intent in my commute cars is always the best SQ possible. My question: does anyone here have experience with Alpine's Imprint system? Is it worth the $200 for the calibration mic and interface or should I stick with my tried and true EQ based on RTA readings?
