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


I am reading all this stuff about buying high-end DACs to bridge the gap from PC to system. Why aren't more of you running a signal adapter from the PC to your Pre/Pro or Receiver? Many Pre/Pros and Receivers have excellent DACs. We spend big bucks on these pre/pros and then ignore the DAC capabilities. Your thoughts?

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.
You are right. If you had a high-end processor like the Theta Casablanca, there is absolutely no reason to buy a separate DAC.
I've been wondering about the same issue for a while. I haven't currently delved in, so my comments are based on reading.

You can buy a used Proceed AVP or Theta CasaNova for less than 1000. Some commonly mentioned DACs are the Benchmark (around 1000), the Del Canto (2500) and the Musical FIdelity xDac (like 1500.)

So it seems a matter of how much you want to invest. A true high end DAC can exceed the price of a very nice pre-pro. So it makes sense that it would probably better the pre-pro when you consider the many functions of the latter. With that said, the pre-pro is pretty versatile and something like a used Proceed or Theta are big bang for the buck.

Just some thoughts.
Sorry I've been late to respond back, Puerto. I was agreeing with your original point. What I stated about ADC applies when the chain is Digital Source > DAC > Processor > ADC > processing > DAC. In other words, if you have a digital out from the source and you throw a DAC in the chain before the processor, it may well be that the processer immediately (and without option) does an ADC. This would be the case with Meridian for example.

I guess I meant to say that adding a DAC in that specific instance is actually a negative since it causes two more conversion steps to occur.

But for many (those without high quality digital domain processors) the outboard DAC is better than a cheap one that my be "onboard." But only if they have an analog pass through (that avoids the ADC - DAC step in the processor). Sorry I was not more lucid!
