Read my reply in another thread. The plate-based TS-P682s are superior to the coaxial Pioneers. Of course, if you like you music loud and with solid bass, stick with the 6855/6865s. However, the 682s are much better in the neutrality department and the vocals are far more engaging. Treble is better defined and smooth as well.
I got a Blaupunkt head unit because I wanted to maintain a Euro sedan image.
