You're going to plug the analog output of a DAC cable into the analog output of your pre-amp to connect it to . Although the two buttons have both the same on/off symbol beneath, the left button turns the unit on and off, while the right button goes through the inputs. The bass of the D03 is clearly designed to be completed by an active subwoofer, and that is not an optional, but more of a design choice. The USB input allows for signal decoding as high as 24 bits / 192kHz, the DAC inside being pretty good for the job. I wouldn’t risk it with entry-level amplifiers, I heard some horrendous performance from entry-level AMPs, with some of them having distortion that’s unbearable, buzzing and a high pitched sound, while D03 is clean, silent and plays music.The bass has a much more rolled off presentation over the speaker output, but it has an active sub output, and D03 is more detailed, has less audible distortion and better details than A50. As long as your speakers don’t cost above 1000 USD, both of those are good amplifiers, and the rule here is that A50 has better bass for speakers, if you don’t have an active sub. The main difference between the classes lies in how much power they require and how much heat they generate. For this reason alone, it is the best speaker amplifier you can purchase if you have less than 200 USD.

It was much easier to understand what people were saying (I tried sitting closer to the TV so see if there's a difference and there wasn't much). It has two inputs, one AUX input, which is convenient for traditional wired analog signal input; there is also one Bluetooth wireless input, which can be easily connected to Bluetooth devices such as mobile phones and computers, without being bound.Your stereo system can sound no better than its worst component, and will almost certainly sound worse. Most of the circuitry is digital so the only areas you might want to play would be round the main power supply capacitor. And both the DAC cable and the Modi are USB devices which you are trying to connect with no USB host?
