Conrad Johnson Design HVA1 headphone amplifier


More information about the latest Conrad Johnson Design amplifier. The HVA1 is a reference quality single-ended class A triode amplifier designed to power low-impedance headphones (around 20 to 32 Ohms). The HVA1 accommodates two line-level inputs. Power output is 3 Watts into 20 Ohms. The enhanced triode circuit (similar to that introduced in our flagship GAT preamplifier) employs two 6922 vacuum-tubes for voltage gain coupled to a high-current FET buffer stage (source follower). Each of the two channels is powered by its own Independent DC regulator. CJD Teflon capacitors and Visahy resistors are featured in the circuits. The level control is a discrete stepped attenuator constructed entirely with Vishay resistors. The circuitry is housed in a heavy, elegant aluminum chassis dressed with anodized brushed aluminum panels on front, sides, and top.

The US suggested retail price for the HVA1 is $7500 (international prices are set by conrad-johnson importers and will vary depending on shipping costs, duties, taxes, etc.). HVA1s are now available for immediate delivery.
