While yes the Modwright is a better unit I fear a similar thing might happen?
I would be shocked if the Modwright didnt out perform the Hagerman. I mean the power supply and the transformer alone are larger than the Hagerman (not that size alone matters) Plus the addition of the Modright capacitors. Not to mention the ability to switch between the 2×6SN7s or 2×6922s on the fly. With the extra cash you could roll a bunch of tubes through there to dial in your warmth and dimensionality you desire. As apposed to a shot and hope you hit the mark with a new DAC.
