Elemental Amps is proudly to present the Elemental Sigma, a class-A valve/Mosfet
hybrid headphone amplifier. Targeting entry-level price and high-end performance,
Elemental Sigma is a unique product. Just close eyes and hooking up favorite
headphones, you will be surprised by what you have heard. A powerful and delicate
sound accompanied by the warmth of valve, a wonderful combo.
Dual mono construction in a compact chassis
By trimming down unnecessary luxury and focusing on core competence, we are
able to build Elemental Sigma in a dual mono configuration, a highly touted feature
in high-end gear.
Two military NOS 6AK5 tubes are the center piece of each
channel’s gain stage.
They deliver rich harmonics, which are the charm of single-
ended topology drawing countless audiophiles’ addiction.
Followed by class-A power MOSFET output stage, it provides almost limitless driving current while preserving the tube’s charming signature.
The configuration also guarantees best channel separation (stereo image), easy maintenance and adjustment on individual channel.
Thoughtful design through smart simplicity
First, there is no pop noise during power on and off. You no longer have to worry the pulse
energy may cause damage to precious headphones.
Secondly, the volume adjustment is adapted to logarithmic curve, the most natural to human interface and hearing by integrating the gain of amp and linear potentiometers.
The Heart of Sigma, 6AK5 military NOS valve
Developed by Bell Labs / Western Electric and used extensively as an I.F. amplifier in
WWII radar systems, 6AK5 yields excellent high-frequency performance. On the other
hand, a poorly designed 6AK5 tends to be unstable.
We carefully characterize 6AK5 to be audio amplifier that delivers transparent and airy atmosphere rare to find in peer products.
Another advantage is easy to find equivalent replacement at reasonable price for tube rolling.
