Is USB overrated as decent digital source?

I traded my fully modded Modwright 999es for an expensive USB converter. The converter/DAC outperformed the 999es on every level. I will never go back to a CDP. BTW, The Modwright was much more expensive than the converter plus a DAC.

Modwright $1500 to $2500. vs.
Converter $400 to $950 plus the price of the DAC of your choice. Mine total was $1100.

Expensive ? What about the Hagerman Technology HAGUSB for wopping total of $129?

That is the first one I would try to do the switch to USB digital.

I have an Ayre D1xe player over 10K, and I just bought a Wavelength Cosecant USB DAC a couple of months ago. The Cosecant is every bit as good as the Ayre and when you add in the benefits of having you music in itunes it's the clear winner.
