I should note... that the H590 does not route the external preamp directly to the amp of the H590, but to the preamp of the H590. So... while you can add some tube effects to the H590, you can do so only through the H590 preamp. But, you still get some of the benefits of the external tube preamp.
Hegel says they do this to assure the correct matching impedence between the preamp and amp - which assures the Harbeths benefit from the H590.
Whatever... it works well.
