My guess is that you would be much better off buying a decent preamp with an analog volume control than adding a separate DAC to your system. Digital volume controls are lousy in my experience and I have had little success going amp direct from a digital source (DAC or CD player) into a power amp.
Manley makes some great preamps that would probably sound great with your Manley monoblocs...if I were you, I would look for a Manley Shrimp before plunking down a lot of money on an outboard DAC.
