了付好耳机，你需要个耳放因他能比糟糕的声卡或者随身听驱动耳机振膜更好。
With decent headphones, you need an amp because it can drive the diaphragms of the headphones much better than a crappy sound card (or CD player).
头领的EF5台式胆石混血耳机放大器（$399）是两箱式组合设计，一个是分体电源，另一个是耳放。
Head-Direct's EF5 Desktop Tube Hybrid Amp ($399) is a two-box affair; one chassis is the power supply, the other is the amp itself.
好吧，这使我不仅仅需要一个200美元的耳机，还要几百美元的耳放和DAC。
Ok, so that makes what I need not just $200 for headphones, but a couple of hundred for an amp, and the same again for a DAC.
