Hello,
I have a D200 mkIII and no noise with my speakers that are sensitives : 95db/w/m (Tannoy GRF).
But you should check the gain setting of your amp. On GamuT amps you can set the gain between around 20db and 35 db. The default setting is high : aver 30db, if I remember.
You can test with a lower gain, like me : I use the lowest gain in my system.
In order to modify the gain, you have to remove the top plate of the amp and select with some little switches (two by side, located on the top of the power circuitboards).
Best Regards
