Quality amplification can improve the sound for any pair of good headphones

Depending on your headphones, there’s a good chance a quality headphone amp — or a headphone amp/DAC (digital-to-analog converter) combination — can breathe new life into your music. A headphone amp raises the low-voltage audio signal from a source device (be it a turntable, PC, or smartphone) to a sufficient level such that it can be converted (or transduced) into sound waves by the speakers inside your headphones.
