Difference between a DAC and Integrated DAC/Amp

post #1 of 3
Thread Starter 

Ok, so a DAC you cannot adjust analog volume.  The USB headphone amp has an integrated DAC with the headphone amp.  What is the difference in the signal coming out of the DAC>Amp>   and DAC> ?  

 

I'm trying to figure out if I can use the integrated DAC/Amp as a DAC for another amp.

If you're talking about using the lineout there's no difference between one device having an amp built into it or not. It will still be about the DAC section's circuit, having an amp will not adversely affect a DAC circuit - the question is how good that section is. Now if we're talking about the amp section's performance vs a dedicated power amp, the question is whether the power supply design on the DAC-Amp adequately supplies both sections, and how much power we're talking about here (like, don't compare an inexpensive DAC-Amp with a 150mW @ 32ohm headphone amp vs a discrete Class A pure amp with 500mW at 300ohms) that your headphone would need.

In practice, it should all be well under the threshold of audibility. There are better things to worry about go ahead and double amp if you have to. Just don't overdrive the input to the second amp.

The general rule of thumb in modern home digital audio is "If you can, just plug it in and see if it sounds good. It probably does." The only trick comes when you plug headphones in.
