Why use a headphone amplifier?

The standard headphone sockets on speaker amplifiers or CD players are not a very good way of connecting reference headphones, they may allow sufficient volume levels, but this has nothing to do with “properly” driving that headphone.

A quick inspection inside these pieces of equipment, often reveals a very basic circuit for the headphone output, with many speaker amplifiers simply having a tap from the speaker line with resistors, some may go a little further & have a low cost op-amp based circuit, however these are quite often very basic in design using lower grade components. A dedicated headphone amplifier is designed for use only with headphones, as such it provides a pair of headphones with all they need in order to be properly driven, a poorly driven headphone can often sound flat or lifeless.

Reference quality sound...

Our reference headphone amplifier delivers a true reference quality sound that is both neutral & uncoloured, having a completely even frequency response regardless of whether the headphones are 25ohms or 600ohms, retaining all the musicality & dynamics with power that makes music so much more enjoyable.

Being neutral in this way avoids many of the usual pairing problems, the amplifier basically allows you to hear how your headphones are supposed to sound.

We have built these amplifiers for many customers from enthusiasts who just enjoy listening to music, to voice over artists & home recording studio owners, it is the result of years of design & perfection, therefore the amplifier has gained a reputation for its sound quality & attention to detail when it comes to build quality.

High power for demanding headphones...

The reference headphone amplifier has been designed to meet the requirements of all headphones & has been extensively tested with a majority of popular models from Sennheiser, AKG, Beyerdynamic, Fostex, HiFiMAN etc, including the infamously hard to drive HE-6, of which the headphone amplifier effortlessly drives with plenty of headroom in reserve so musical transients are never restricted or compressed.

3 Stage adjustable gain...

High power is not always required, especially when using very sensitive headphones, therefore the amplifier has a three position gain switch at the rear of the amp, this allows you to fully customise the power output to perfectly match any type of headphone, any of the three gain settings can be used regardless of input level.

Hand crafted front panels...

The front panel, volume knob & even the feet are all machined by hand here in the workshop. Crafted from solid aluminium bar stock, they are all individually machined, finished by hand, anodised & then screen printed, these are all individual processes that we perform right here in the workshop.

A high quality preamplifier...

The amplifier can also be used as a very high quality pre-amp, the gain can also be adjusted to match the input sensitivity of any power amp, in recent tests this has proved to be an excellent feature & allows all of the qualities of the amplifier to be transferred to active studio monitors or a home Hi-Fi speaker system.

Soft start feature...

The amplifier also features a unique soft start, this virtually eliminates any turn on transients & helps to prolong component life, it is a feature often commented on & appreciated by owners of the amplifier.

Quality components for performance & long term reliability...

Inside the main aluminium chassis you will find some of the very best components, these have all been chosen not only for their performance, but also their reliability over the more common & cheaper components often used. Vishay Dale precision resistors are used throughout along with various other high quality components from Panasonic, Alps, Wima etc.
