E17 versus E7
Not even close. Aside from the improved features and specs, the E17 also blows the E9 out of the water. There is no comparison here. Tonally, the E7 sounds thin on the mids and lows, and the soundstage is not that impressive. If I can add something, also put congested mids into the list of the E7 features. The E17 on the other hand has a much bigger soundstage, and a more likeable tonality. Good full mids, good bass, spacious sound, all around musical.
