Why are DAC's so much more expensive than transports?

I'm beginning to realize that hi-end audio is not just about achieving some technical absolute. It's also about finding the right sound that each person enjoys.

@jasonbourne71 - I don’t have your experience in audio and hi-fi equipment. I only really started purchasing and listening to nicer equipment the last 4 years or so. But in just that short time, I’ve experienced different dacs and their unique attributes. You seem to suggest they are largely all the same, which has not been my experience. 

To understand DACS you need to.understand the basic modules that comprise a DAC, what they do, and what, if any, impact they have on sound quality. That includes power supplies for both digital and analog circuits, digital input stages including Wifi/Ethernet, the DAC proper, the reconstruction filters, and analog line stages. That's far too much to go into here, so suffice to say any bit-level digital errors are extremely rare, The real ’opportunities’ for SQ impacts lie in the reconstruction filter and analog output stages.
