Premium Modification Descriptions-
~Power Supply Mods Replace diode bridges with ultrafast rectifier diodes to remove grain/glare and increase resolution and bass. Replace all capacitors in circuit with the Rubycon Ultra Low impedance capacitors for far less noise, faster reacting circuits giving way with much more headroom. We rewire some of the voltage rails to rework the power delivery to critical circuits for lower noise and more current.
~DAC Board Upgrades We replace about a large number of capacitors across the board with the incredible Rubycon Ultra Low impedance series caps. This really brings more life/speed/emotion into the music! Replace ALL operational amplifiers to the best sounding versions on the market made by National Semiconductor! Talk about transparency through the roof! Remove unneeded circuit parts to improve signal quality and integrity.
Internal Soundcoat Damping- Apply Soundcoat damping material to specific areas to minimalize the amount of internal vibrations and ringing.
~DEXA Clock Reference Clock Upgrade The OEM Benchmark clock is a basic pierce oscillator which feeds directly into the ASIC (DSP) chip. Phase noise and power supply injected noise here is high affecting all audio playback with "jitter". The DEXA clock has an extremely low phase noise oscillator (around 1.5 picoseconds Jitter RMS) and dramatically improves all areas of playback. The ultra-low jitter and noise performance of the D-Clock immediately releases impressive sound quality & shifts the players tonality to remove hardness & harshness; the overall frequency range is more natural and unforced. Lower frequencies on playback have greater impact, weight and control. Greater dimension is added to music and movies, vocals and instruments having improved spatial qualities with a more solid, palpable feel. The DEXA clock has a very unique function of isolating the clock signal ground to the power supply ground, so there is no ground loop, and also there is no Mains Noise injection for the cleanest clock signal possible.
The DEXA D-Clock now eliminates the need for a dedicated (and costly) external dedicated power supply due to its inherent mains/ground isolation topologies. Highly Recommended by all means for the best audio performance!
