Grace Design M905 as a preamp


Dear all,

i am interested in the Grace Design M905 as a preamp.
its class A rated on stereophile as DAC, but its actually a monitor controller in a studio application.
That means its a pre-amplifier in hifi speak. When I try and find feedback on the M905 as a pre-amplifier i find no information.

My speakers are ME Gethain RL901k.  

Can anybody help?
