Lejonklou Giella PI | Headphone Amplifier
Reference all-analogue headphone amplifier
The Lejonklou Giella ∏ is an all-analogue headphone amplifier with a single purpose:
to give you a thrill when listening to music.
Not accuracy for its own sake. Not features. Not convenience.
Giella ∏ exists to make music gripping, meaningful and emotionally convincing through headphones.
At Authentic High End, we consider Giella ∏ a reference for serious headphone listening — not as an alternative to loudspeakers, but as a complete musical system in its own right.
Why “Giella” — Your Headphones Need a Language
Giella means “language” in Sami.
That choice is deliberate. Headphones do not automatically communicate music in a meaningful way. They need an amplifier that understands how to translate electrical signals into phrasing, rhythm and emotional intent.
Giella ∏ was created to give headphones that language — so music stops sounding reproduced, and starts sounding expressive.
Designed by Listening, Not by Spec Sheets
Designed by Fredrik Lejonklou, Giella ∏ follows the same discipline as all Lejonklou products:
every decision is validated by listening and comparison.
Electronic components are individually measured and selected into tolerances that cannot be bought off the shelf. Specific combinations are chosen after hundreds of comparative listening tests, always asking the same questions:
What makes the music more gripping?
What reduces involvement?
What keeps you listening longer?
Only the answers that served the music survived.
From Giella to Giella ∏: A Necessary Evolution
Project Giella began in 2014.
The first complete design was simpler and significantly less expensive than the final product. By the summer of 2020, the circuit had been refined as far as it would go — technically excellent, enjoyable to listen to, but not thrilling.
That wasn’t enough.
Fredrik redesigned the amplifier using a different set of components and adopted the power supply architecture from the Entity Moving Coil phono stage. This transformed Giella into something fundamentally different. After months of tuning, it became an amplifier he used every day.
When Giella was introduced in December 2020, early feedback was overwhelmingly positive — with one important exception. Some extremely current-hungry headphones revealed limits in bass control at very high volumes.
That feedback was taken seriously.
Work resumed, and only stopped when the amplifier became both more powerful and more musical.
The result was Giella ∏, introduced in March 2021.
Almost all original Giella owners chose to upgrade — a clear indication that the musical gains were unmistakable.
Purely Analogue — By Choice
There is no DAC and no digital circuitry inside Giella ∏.
This is not a limitation, but a deliberate decision. The absence of digital elements allows the analogue signal path to reach a higher level of refinement without unnecessary cost or compromise.
Giella ∏ is designed to reveal the quality of your source. The better the source and the headphones, the greater the musical difference becomes.
Listening Experience
Giella ∏ does not exaggerate detail or create artificial space.
Instead, it delivers meaning.
Music flows naturally. Rhythms lock in. Dynamics arrive with intent rather than force. Headphones feel less like transducers and more like a direct connection to the performance.
This is an amplifier that encourages long listening sessions — not because it sounds “impressive”, but because it makes music hard to turn off.
Power & Compatibility
Giella ∏ can drive any pair of dynamic headphones, including demanding, current-hungry designs, with authority and stability.
It remains composed at higher listening levels and retains control in the bass, even when the music becomes complex or intense.
More Than a Headphone Amplifier
In addition to its headphone output, Giella ∏ features left and right analogue line outputs.
These allow Giella ∏ to function as a high-quality analogue preamplifier, feeding a power amplifier and loudspeakers. This makes it possible to build a compact yet deeply engaging system — ideal for an office, studio or second listening space.
Why We Selected Giella ∏ at Authentic High End
We selected Giella ∏ because it treats headphone listening with the seriousness it deserves.
It does not chase trends or features. It focuses entirely on musical communication. In our Brussels listening rooms, Giella ∏ consistently proves that headphone listening can be every bit as emotionally involving as a carefully set up loudspeaker system.
