AudioValve puts most of their budget towards the sound quality of their design and components rather than all of the audio jewelry and marketable designs featured by some of the comparable sounding amplifiers on the market. On sound alone it outclasses its price point, as for performance, design, fit and finish it far exceeds our expectations and represents a truely exceptional product at double or triple its price catagory. Sound wise this amplifier delivers great tonality, world class 3D sound stage, a noise floor on par with all but the very best valve based amplifiers, and macro and micro dynamics in spades. The sound quality of the Solaris is of absolute top reference level for a headphone tube amplifier. The pros to this are a very low noise floor, low distortions, high frequence range, high damping, very natural and musical tonality, wide impedance matching, perfect open soundstage and so on. This amp isnt for the weak of heart it is an audioholics dream. Highly recommended is an understatement, we cant tell you how impressed we have been with the arrival of this headphone tube amplifer. Output is 8 to 12 watts depending on headphone impedance and incorporates speaker outputs to drive highly efficent monitors.       Collection is allowed in JHB area, please make contact with us once the order is placed.

Product Overview MSRP 259 Euro    Elemental Watson Class-A Valve/Mosfet Hybrid Headphone Amplifier Features Full Class-A amplification at all stages Dual mono design for best channel separation and stereo Quiet operation during power on/off and low residue noise NOS 6AK5 military grade tubes for longer stable lifespan Extended bandwidth meeting Hi-Res standard Optional pre-amplifier output with dedicated terminals High performance at entry level price The amplifier sets a new standard on cost/performance ratio 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 channels 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 tubes 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.
