LEJONKLOU Giella & Giella ∏ Headphone Amps


Headphone amplifiers that give the kind of exciting, visceral sound Lejonklou HiFi products are known for but now when driving headphones.  They also make an outstanding single input preamp.  They may even convert non-headphone users!


Your headphones need a language


Giella is an all analogue headphone amplifier with a single purpose: To give you a thrill when listening to music.


Therefore its design is simple, yet extremely refined. Like with all my products, the electronic components are measured and selected into tolerances that are impossible to buy. And the specific combinations used in Giella are chosen with hundreds of comparative listening tests. It's all about listening and deciding what's better and what's worse. What makes the music more gripping and what makes it less.


Giella started with a circuit idea in 2014. The original design was simpler and about 2/3 as expensive as the final version. In the summer of 2020, I had tuned every part of the original circuit and couldn't improve it any further. I enjoyed listening to music with it, but I wasn't thrilled. I knew that it wasn't good enough. So I redesigned it with a different set of components and the power supply used in my Moving Coil phono stage Entity. This new version of Giella was a completely different beast. After spending a few months tuning it, I found myself using it every day.


There's no DAC or remote control in Giella, because the absence of anything digital inside Giella helps it reach a new level of performance without adding massive cost.


Giella can drive any pair of dynamic headphones, with outstanding musical quality. The better your headphones are, the bigger the difference will be when comparing Giella to other headphone amplifiers.


The only extra feature on Giella, apart from controlling the volume and driving your headphones, is a left and right analogue output. These can be connected to a power amplifier and speakers. Giella will then function as a very high quality pre amplifier. A compact and very engaging system, perhaps for the office or the cottage, can be built around Giella.


Giella ∏ was designed to take Giella even further in allowing it to power the least efficient dynamik headphones at the lowest frequencies to the highest levels.  A much more potent regulation stage allows the Giella ∏ to output over 5 times the voltage at 20Hz into a 32 Ohm load!  This more powerful supply according to Fredrik “kicks the circuit of the Giella into a higher level of performance”.  It definitely improves the musical perfromance into any headphone and as a preamp too.


Giella is Sami for 'language'.
