Hi hotaudio40:
Do you have a standalone USB DAC or a USB DAC+amp with standalone DAC function?

Then there is NO caps in the Audio signal of the DAC. Now this WON"T WORK if your amplifier is DC coupled, but as far as I know, 99.9% of amps are AC coupled. I do make DC coupled amplifiers, in fact all my TPA6120 models are DC coupled now, so you CAN NOT use this DC coupled DAC with my high-end headphone amps... at least not in DC mode. But you can use it with just about all other amps as far as I know. You'd have to check the specs on your amplifier or look at the schematic to see if the inputs are AC coupled. Chances are they are. In this model, NOT THE ONE ABOVE, that one is AC coupled... I put a switch, to select AC or DC output coupling of the DAC. It seems to work fine with the amps I've tried, but I know that they have AC coupled inputs. I'm going to call it the "DAC STRAIGHT DUAL MODE" It is built, just not listed anywhere till testing is finished. hotaudio40 |

I just want to find a affordable decent usb DAC connect my PC(foobar2000) and little dot mKIII amp. Could you please suggest one model for me? Just simple and better SQ. |

(or a 5000+ ohm HP So, yes you can use it for your Little Dot MKIII A normal amp has an input impedance around 50.000 ohms If it is an capacitor-less version of the DAC supreme, it uses the PCM2702. Well the best DAC depend a little on your budget. The DAC DESTROYER and then MARK IV USB DAC use the PCM2705 chip HOTAUDIO SUPREME use the PCM2702 All of Daves DAC's have a pre out (except HOTUSB 1), so you can use all of them to feed your amp... I have the supreme, and I use it to feed a Head-direct EF-1 and I am very pleased with that DAC. So the supreme will be a safe bet. Correct me if I am wrong Dave. |
