I'm no hi-fi geek. I'm no expert. But I specced Dynaudio and have NOT regretted it at all. The sound is so rich, deep, and crystal clear - it makes the music you enjoy even more enjoyable. I haven't compared it to the standard speakers in the mk7, but compared to all my previous cars with standard systems, it's just 100% better.
It's a revelation to have a throughly good sound system, so I would definitely recommend it.
