Hegel Integrateds: Anyone using the internal DAC?

Thinking about a used H70 integrated. I would like to know your thoughts on its internal DAC. Has anyone found the Hegel's internal DAC to be better than their separate DAC? If not, was it close? Either way, what was the DAC you had that you preferred or didn't prefer?
Hegel is primarily a DAC specialist, you cannot go wrong with their DACS for the money!
