Headphone amplifier

The Tom Christiansen Audio HPA-1 is an exceptional headphone amplifier for the most demanding audiophiles and sound engineers. Its high power, ultra-low distortion and exceptionally high dynamic range make it one of the highest fidelity headphone amplifiers ever measured.

The HPA-1 is completely transparent. It has no sound signature and offers precise reproduction of music without any fatigue.

Audio Science Review's Opinion

"The Tom Christiansen Audio HPA-1 delivers exceptional measured performance. It has no weaknesses, either subjectively or objectively. It is completely transparent and, as such, joins an exclusive club of half a dozen headphone amplifiers that deliver such superlative performance. The cost is high, however, second only to the Benchmak HPA-4. Whether the look and feel of the unit, plus the superb brand support, is worth the extra money is up to you to decide."
