Any Ghent Audio users here?
I am curious about these amplifiers and would like to know some opinions. 
Also, if someone compared Ghent products with other class D amps at same price range - Tripath, Ice power, Ncore, etc. 
I'm a rookie in class D and would like to know the difference between the various chipsets. 
(Unfortunately I don't have easy access to listen to them).
