The amplifier sets a new standard on cost/performance ratio

Elemental Amps is proudly to present the Watson, a class-A valve/Mosfet hybrid headphone amplifier. Targeting entry-level price while with high-end performance, Elemental Watson 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 Watson in a dual mono configuration, a highly touted feature in high-end gear. Two military grade 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 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

There is nothing like cost down design in Elemental Watson except cosmetics. 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 gain adjustment of amp with linear potentiometer.

 

The Heart of Watson, 6AK5 military 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 for audio amplification 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.
