All I can say is you must try this! 10 band EQ, with selectable ranges of +/- 3,6 or 12 dB. There are sliders for 31, 62, 125, 250, 500, 1k, 2k, 4k, 8k, & 16k (hertz) frequencies, plus one for gain. The EQ operates extremely smoothly, with only a few milliseconds before the setting is applied to whatever your listening to, and no disruption. The sliders flicker red with the music gain threshold for each frequency indicating that it may be too much and cause cutting out or digital distortion. It has individual sliding, narrow banding or wide band (where several slide together, slightly less than the one next to it). -Here's the kick in the ass... Mixzing allows for each song, album, genre (IDK about play list) to have it's EQ setting REMEBERED! So far the only down side I have found is that only MP3 format is supported by the EQ, but they are working on other formats. This is VERY cool!
