DACs and bass response?

I've owned several DAC's to date and some were more on the "thin" side in terms of Bass and others were a bit "thicker".

I have a hunch that the power supply design and how well its isolated from the rest of the sensitive pieces play a pretty big role here.

Of all the DAC's I've tried to date the best ones have been from EMM Labs/Meitner when it comes to deep/textured and clean bass output. I hear DCS is also very good in this area but I've not had the opportunity to hear that for myself, yet.

Totaldac has the best and most focused bass I have ever heard. It is also the most analog sounding digital I have heard.

@luizfcoimba: this is a demo unto supplied by a dealer who assured me it was well burned in. Overall, it sounds wonderful. . . except for the lack of bass, that is. 

@eniac26, paul79, I'm pretty sure I cannot afford Totaldac, Meitner or DCS but thanks for the suggestions. 

Does every component in a system have to add the designers interpretation of accuracy ? Is there not a measurement for bass so we are getting the correct amount of bass on a recording ?
