How can you be sure of this?
Without trying the product for yourself or having an unbiased reviewer like Amir check it out?
Passing judgement on something before ever having an experience with it. That does not seem rational.
You need to read a few DAC reviews by Amir. Dac's are basically a solved problem. Even the least expensive DAC of today measures and sounds (b/c things sound like they measure!) better than state of the art analog tape and vinyl playback. Fact is, any number of extremely well measuring DACs reviewed by ASR have levels of distortion and noise so low as to be inaudible, and all for $100-200 in many cases for unbalanced RCA output, or $200-500 for balanced. Look for the Topping, SMSL, or even the Schiit reviews.
There is no reason I personally can conceive of (at least for measured and, therefore, audible performance) that can justify spending much more than $500 for any two channel DAC. Moreover, if you go to Archimago's musing and read a few of his articles on DACS and jitter, you will come to understand that jitter is not an issue at all with any well designed contemporary DAC--which is to say almost all of them. The most likely exception in that regard are the "audiophile" dacs with ladder resistors, FPGA's, custom opamps, and--worst of all--multibit DAC chips.
