To me, the Allnic HPA-300B represents the pinnacle of one's personal preference for SET sound with headphones and is my favorite headphone amplifier of all time - for its versatility in both tube rolling and voicing the circuit to each of our own personal resonance. My own journey has led me to the realm of high-efficiency loudspeakers and single-ended, direct-heated triodes. The HPA-300B excels in all aspects, allowing one to take full advantage of any 300B's sonic capabilities and striking a balance that drives the most challenging planar or ribbon-type headphones without strain and the most efficient dynamic designs without overdriving. The fact that the HPA-300B is also an integrated amp for efficient, SET-loving speakers is a huge bonus. This versatility makes the HPA-300B 'the quiver of one' to serve most every need.

"Context here, as with so much in audio, is everything. There's a reason why almost all manufacturers - Allnic included -produce dedicated headphone and speaker headphone amplifiers. However, Kang Su Park clearly spies a certain cohort of buyers who demand excellent performance from headphones and loudspeakers... and compactness and affordability. Allnic HPA-300B is for them."
- Kevin Fiske, HiFi+, 2025

Context is everything, and the HPA-300B provides the freedom to voice your system. The HPA-300B's MRSP is $13,200 USD and can be factory optioned with the RAAL "Direct Drive" described below at no extra cost.

All current HPAs feature Allnic’s unique 61 step constant impedance bridged type attenuator - allowing for preservation of soundstage and dynamics over the complete volume range and eliminating that often too loud "sweetspot" needed to achieve a truly immersive experience.
October 2025 forward production features an engraved aluminum attenuator cover.
2025 has been monumental for Allnic, with the release of a new Headphone Amplifier product line. Foremost, in collaboration with Danny McKinney, the North American RAAL distributor, Allnic released an optional RAAL "Direct Drive" connection for ribbon headphones to replace one of the balanced outputs.
In the HPA-300B the optional 0.2 Ohm "Direct Drive" output is implemented using Allnic's existing output transformer at no additional cost.
