I'm using the Delos in a new Graham Phantom II. Once fully setup the treble really settles down to a more appropriate level which is entirely natural in it's presentation. I'm not sure if mine is suffering from "low riding" syndrome but the sound is excellent and getting better as the cart runs in. For me it was also a toss up between this and the Axia. I was seduced by the engineering sales patter on the Delos.... :o)
