Recommendations for a new integrated amp for Vandersteen 3a speakers

I've owned 2 of the integrateds you are looking at.  First was the Vincent.  I liked it but it had problems with the tubes.  German design, chinese build.  Sound was very pleasing.  Laid back presentation.  The music traveled to you it didn't attack. Had tone controls which is rare. So after that I traded to the MF 6si....not 6i.  Overall I like the MF better.  This thing is a beast and will handle anything you throw at it.  As you raise the volume you feel it building power without loss off nuance.  You can play a great classical piece and let flow and right after that smack on some hard rock and it will give you the meat and potatoes without sacrificing detail.  Lastly, I've heard the rogue as well that is a fine choice too.  good luck.
