As result I am clearing out my TCA headphone amp offerings. The TCA HPA 10 will be discontinued once the current inventory has sold. The TCA HPA 10 is a nimble, yet powerful, headphone amplifier.

the THD+N of the HPA-1 is still below the measurement limit of the APx525

It should be noted that the distortion is nearly two orders of magnitude below audible at all power levels below clipping

The HPA-10 shows no residual mains hum

To further increase the performance of the output stage

In addition

Common-Mode Rejection

2 Hz – 550 kHz

The THD+N vs output power plots mostly show the THD+N floor of the measurement system
