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 stock 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 and DAC. 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!

~Digital Input connector upgrade to WBT Nextgen
Copper (Add $40) or Silver (Add $80)
Replace stock BNC connector with WBT Nextgen copper or silver version for optimal
connection via RCA input. Removes eddy current issues and minimalizes unneeded
contact surface area for the best signal transfer characteristics.
The prices went up from WBT recently......

DEXA Neutron Star Flagship Clock Upgrade Add $400-
This flagship clock upgrade will replace the regular D-clock in the premium modiifcation
that feeds the internal DSP and DAC chips for the very least amount of noise and jitter
possible and the highest potential of performance that is possible within todays
technological limits. The improvement is about 40% over the already potent D-Clock
and allows you to hear deeper into the music with more clarity and finesse. Well worth
the price for the best performance possible!

Complete Analog Output stage Rebuild- Add $500-
Completely disconnect the stock Benchmark DAC1 analog output stage (many
active parts) and replace entirely with passive very high quality Audio Signal
Coupling Transformers (also other parts upgrades included).
The stock Benchmark DAC1 output stage is mediocre in build and sound quality.
However, there are MANY ACTIVE parts in the signal path, such as cheap industry
standard op-amps and transistors. There are also many resistors in the signal path as
well. This is not the most optimal topology for signal coupling and HF filtering.
Our approach is simple and instantly effective:
Completely disconnect the entire active analog output stage, and replace it with a set of
very high quality Audio Signal Coupling transformers! Now with the transformers we can
now effectively and inherently provide galvanic isolation from other components in your
system. The transformer stops High Frequency noises that occur from other
components in your system. The noise floor in your music drops to a complete dark and
black level. More detail comes out of the music. The soundstage appears much larger,
wider deeper with a bold lifelike stance.
If your looking for the best sonic performance from your DAC1, this modification is a
must for a complete transformation of your sound. Only available here at ASi!
XLR outputs are 100% true balanced and is the preferred output connection.
The internal gain controls and calibration controls do not work anymore, they are part of
the stock circuitry that is bypassed and rebuilt upon.
