Elektra Reference HD Australian made audiophile power amplifier
The amplifier consists of two owersized heatsink blocks for efficient cooling which have the added advantage of enhancing the structural rigidity of the chassis to minimise any microvibrations. The power transformer and supply capacitors are centrally located in the chassis to further reduce the effects of vibration and electronic interference.
The amplifier's circuit, from the input to the output stage, uses an improved linear phase and low distortion current feedback circuit topology. This is optimised for excellent high frequency and phase performance. The circuit board layout ensures the minimum signal path length.
All transistors used have exceptional audio qualities due to their linearity and high frequency performance. The current feedback circuitry allows for fewer parts in the signal path and improved performance over standard designs in terms of phase and frequency performance.
The Elektra Reference HD has a custom designed power transformer to match Arthur's specification. The transformer is fully encapsulated (potted) which both improves performance sonically and further eliminates mechanical vibrations that affect the surrounding circuitry.
Custom designed electrolytic capacitors have been developed to complement the circuitry which uses an exceptionally thick 4N (99.9999%) high purity aluminium foil and a natural fibre (silk) separator which reduces modulation effects, producing a very musical, full and detailed sound.
