About the HVA-1
The Conrad-Johnson HVA-1 is the company’s first dedicated headphone amplifier, designed as a reference-quality single-ended Class A triode design for low-impedance headphones. It uses a 6922 tube front end with a high-current FET buffer stage, two line-level RCA inputs, and a single 6.35 mm headphone output. The amplifier is built with CJD Teflon capacitors, Vishay resistors, independent DC regulation for each channel, and a discrete stepped attenuator.
