Hi: I am new here and fairly ignorant of the technologies involved. I would like to get an audio system with self-adjusting EQ sliders like my Sony FH 414 had. I could adjust the frequencies for both channels so I could hear drums more clearly out one speaker and Bass guitar out other. I can't seem to find one similar. Maybe the technology has changed? I was told I need to start with a 2 channel receiver and could adjust frequencies for each channel from the remote control. Also, that Sony has a good one for about $200. I really don't know where to start. Any suggestions appreciated. Roland.
