It was explained to me that Cullen was a designer and subcontractor for Paul in the development of several pieces, including the DAC III. Paul gave him the rights to do mods for the units and still have them under the original warranty. Paul subsequently outsourced the production of the units to China under his supervision, but not Cullen. As I understand it, the original units were made in the USA under the eye of Cullen, but not now. I also have heard rumors that Cullen wanted to include upgrades in the origianl DAC but compromises were made to meet certain price points. That is where Cullen gets to do his upgrades. Again, this is all third hand knowledge, not from Cullen or Paul, but from dealers who are close to them.
what gives with PSAudio & Cullen headquarters?
I found it odd that Cullen uses the same photo that PS Audio did/does?? check it out hereCullen and herePSAudio I mean, look at the cars. It's the very same photo. I assume that Cullen purchased the facility from PS Audio? Obviously, one of them superimposed their name on the photo? So where is PS Audio located these days?
