The massive resurgence in the popularity of headphones, spurred on by the smartphone revolution, has created a renewed interest for high quality headphone amplifiers. Like the other components in the Reference 501 system this is a Dual Mono design, with each channel featuring a discrete, all Class-A circuit designed to eliminate any possibility of crosstalk and signal interference. Specialist audio-optimised MUSES8920 OpAmps help provide high-resolution analogue output for any connected headphones.
 
Damping factor, in conjunction with output impedance, is a measure of an amplifier stage's ability to correctly control the headphone driver's diaphragm (the element that moves and so creates sound). Adjusting the damping factor for a given pair of headphones will allow a reduction in distortion and a flatter frequency response. Low end Headphone Amplifiers don't offer such flexibility but the HA-501 provides five user-selectable Damping Factor settings.
 
With a frequency range of 2Hz-100kHz and 1,400mA of output power per channel (at 32 ohms impedance) the HA-501 has more than enough current drive capability not only for the majority of regular headphones (with an impedance range between 80-250 ohms) but also more esoteric, high-end 600 ohm designs. And if you do have several headphones an auto-muting function will ensure you don't get deafened when switching between models with different impedances.
 
As you will have gathered by now the TEAC Reference 501 concept doesn't really do compromise, either on an individual component or a collective system basis. It is a mini hi-fi system whose aim is simply to be the best of the best, with genuine audiophile credentials and offering a level of engineering, flexibility and sparkling performance that puts it, assuredly, in a class of its own.
