To my surprise, the German magazine Bonedo rates the E-A7 very positively (4.5 of 5 stars).
Unfortunately, it's in German, of course.
http://www.bonedo.de/artikel/einzelansicht/roland-e-a7-test.htmlTranslation of a part of the conclusion, dealing with sounds and styles:
In the 1,100 euro class, the Roland E-A7 provides a new arranger alternative which is absolutely convincing. The keyboard has plenty of excellent-sounding tones and styles and also convinces with its high-quality effects. [...]
