I do think that the Luxman M900u has very promising sound qualities - - so much so that it gets me thinking about finding the right speakers to match it! The TAD's are definitely not the right ones, probably more something along the lines of Sonus Fabers would be an outstanding match, I'm guessing.
To stay with the TAD's it would be interesting to try a powerful Pass Labs approach.
