Initial report on the Savant Prestige:
These are the things I notice vs. K10 as of 10 hours burn in, I am not considering this a review.
1. much less bass response
2. wider soundstage (stock cable)
3. harsher highs, but not as harsh as the 4S. Somehow the Savant reminds me of a refined Noble 4S.
4. Sounds amazing with metal...
5. Still above everything, it retains Noble mids.
