Yes, you need both in order to hear a sound outof your headphones/speakers. In my experience, the medium of sound(headphones/speakers) make the single largest impact on soundquality, followed by the amp, then theDAC..
Beside this, what is the difference between a DAC and an amp?
A digital amplifier is really a DAC with ahigher voltage level to some degree. The way they achieve that isdependent on the design. Now a digital amp is built to takea digital input stream and create a high-level signal that issuitable to drive speakers directly.
Likewise, do I need a DAC with my headphone amp? Analog components like a turntable or tape deck don'tneed a DAC – they already put out analog low-voltagesignals – but digital audio devices like PCs, smartphones,iPods, or tablets need both a DAC and headphoneamp in order for you to hear sound through yourheadphones.
Similarly, how important is a DAC?
a good dac increases quality, and volume. Itbasically takes the job of converting to analog form the PC's soundcard to a stand alone device. Sometimes using an AMP without adac may lead to white noise depending on the quality of yoursound card.
What is USB DAC up used for?
The USB DAC converts digital audio signalsfrom the computer to analog signals for the amplifiers andspeakers. Although an analog connection can be made via the outputson the computer's sound card, purists maintain that external USBDACs provide superior conversion and better soundquality.

Do DACs really make a difference?
A massive difference. If you don't use aDAC you won't hear anything at all. DACS can sounddifferent to each other but maybe in ways that you won'tperceive. Some DACS sound brighter or warmer but these canbe tonal characteristics rather than having anything to dowith quality.What is a DAC for audio?

WHEN NOT TO USE AN AMP! Most in ear headphones or earphones aretypically highly efficient so they work well with smartphones orother portable devices without requiring an amp.

DAC. Stands for "Digital-to-AnalogConverter" and is often pronounced "dac." Since computersonly recognize digital information, the output produced bycomputers is typically in digital format.

Once the DAC converts the signal, an amplifiertakes over. The lightning port and lightning input are bothdigital, so the phone does not need a DAC anymore. The iPhone 7 can thus be more battery efficient, andhave room for other components (like a bigger battery) inits slim case.
