Audion Silver Night HP1 Headphone Amplifier
The Audion Silver Night HP1 is a remarkable headphone amplifier that stands out in the high-end realms of headphone audio. Let’s look at its features and capabilities:
Unique Design and Attributes:
- The Audion Silver Night HP1 is designed around the award-winning Silver Night amplifier.
- It shares many attributes with its namesake, including hard-wired in-house output transformers and single-ended circuitry.
- Notably, the HP1 incorporates a new output transformer, allowing it to drive headphones with precision.
Switchable Output Impedances:
- The HP1 offers five switchable output impedance options: 8, 32, 150, 300, and 600 ohms.
- This flexibility ensures compatibility with a wide range of headphones, allowing you to optimize performance based on your specific pair.
Balanced and Single-Ended Outputs:
- On the front panel, you’ll find both balanced and single-ended headphone outputs.
- These outputs are available via either a Neutrik 6.3mm jack or a 4-pin Neutrik XLR socket.
Stereo Input Channels:
- The HP1 features three switchable stereo input channels, providing versatility for connecting various audio sources.
Optional Balanced XLR Inputs and Outputs:
- For those seeking additional connectivity options, the HP1 offers optional balanced XLR inputs and outputs.
- This makes it suitable for use as part of a comprehensive media center setup.
Quality Components and Unique Circuits:
- Audion prioritizes quality by avoiding the use of Chinese components.
- The Triode-based amplifiers within the Silver Night series utilize unique circuits and Audion’s proprietary output transformers.
In summary, the Audion Silver Night HP1 is a rare gem—an SET (Single-Ended Triode) headphone amplifier that delivers exceptional sound quality. Whether you’re using high-sensitivity headphones or seeking an esoteric listening experience, the HP1 has the potential to elevate your audio enjoyment

Description
The Audion Silver Night HP1 hard wired 300B headphone amplifier is a unique product from us and features 8, 32, 150, 300 and 600 ohm switchable transformer output in either balanced or single ended mode. With 3 stereo input channels and a straight through un-attenuated output for direct connection to a power amplifier or similar.
All of our single ended designs use unique circuits and are auto-biased so don’t need regular bias changing or complicated setting up. The HP1 in fact uses a very similar circuit to our already renowned award winning Silver Night.
Sonically, The Triode valves used in the Silver Nights give subtle nuances and texture to the music allowing un-paralleled music finition retrieval. The 300B is a very well know valve that can reproduce delicacies and yet be punchy at the same time.
The Silver Night HP1 300B headphone amplifier is a truly capable product featuring many additions that we have been asked for in a headphone amp, (integrated pre-amplifier, balanced headphone sockets, plenty of power to drive difficult headphones and many output impedance options). The HP1 is designed for ease of use, quality of sound and versatility – “We know you will like it”
The chassis is made of military grade aluminium, with a durable black powder coated finish. The top plate and badge are finished with mirror polished stainless steel.

Options
Product options for the Silver Night HP1 include the optional XLR balanced input output option on the rear
Product options for HP1 headphone amplifier are limited a little by the amount of space available within the chassis, however we are still able to fit a remote control volume or a 48 way stepped attenuator, better signal capacitors, as well as better power supply capacitors and even more silver wire for the full audio path and now we can offer WBT Nextgen RCA terminals, as well as various valve options.
Upgrades & Classes
Upgrade options and upgraded product categories direct from the factory.
We offer 2 upgrade classes for the Silver Night HP1 stereo headphone amplifier.. The upgrade classes are
Insignia Class which uses a full silver wired audio path (less internal interconnect), better graded components again in the audio path, tantalum resistors in the critical places and WBT RCA’s.
Excelsior Class uses the same as above but with the inclusion of Teflon/Tin foil V-caps, Internal Solid Silver wired Interconnect, a 43 way Stepped attenuator, better power supply capacitors, more tantalum resistors and WBT RCA’s.
There are options on both classes for solid silver wound secondaries or primaries and secondaries on the output transformer.
