Why buy a DAC when you have a high end pre/pro?

Kjweisner: No Problem - I got it now! We are on the same page.

Kjweisner: But I'm suggesting that this a DAC transfer. It comes digital out from the PC or Mac and into the Digital "in" of the processor. The Processor, in turn, does the DAC work and gives the speakers an analog feed. Maybe I'm just not understanding what the need is for ADC. Enlighten me please!
I'll be the first to admit that I am not a total expert.

Audioengr: I took the time to read a review on your Proceed AVP (it was very complimentary) and one of the highly touted features was the internal DACs so I have to imagine that your external DAC must be really special.
I did start using my CDP as a transport and noticed an immediate difference (for the better) by using my Krell Pre/Pro as the DAC. I guess you start with the Pre/Pro or Receiver and then experiment from there and take note of what your ears are telling you. Budget also becomes an issue for most of us.

Bmdduck: Your thinking is perfectly logical. Putting your Pre/Pro to the test first seems to be the best first step. One can always add a DAC (and more money) if the pre/pro is not living up to the listeners expectations. I certainly don't mean to imply that money spent on a good DAC like the Benchmark or Bel Canto, for example, is a waste of money. . . It may very well be the next step up the ladder for those who want more! My budget tells me exactly how much I can't live without!
