-Power Supply upgrades/rebuild-
Replace all critical diode bridges with Ultra Fast Diode Rectifiers for removal of glare and
grain. Replace all key capacitors in circuit with and abundance of Rubycon Ultra Low
Impedance capacitors for substantial improvement in power supply filtering.

DEXA D-Clock Reference Clock Upgrade-
The OEM Esoteric master 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 and video formats with "jitter". The DEXA clock has an extremely low phase noise
oscillator (around 1.5 picoseconds Jitter RMS) and dramatically improves all areas of CD,
SACD and video playback. The ultra-low jitter and noise performance of the D-Clock
immediately releases impressive sound quality from all Esoteric Models & shifts the
players tonality to remove hardness & harshness; the overall frequency range is more
natural and unforced. Lower frequencies on CD/SACD/DVD 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 and video performance!

2ch Analog Output Stage Parts Improvement
The 2ch analog output stage section is addressed with better signal parts for a much
better sounding 2ch output. The OEM capacitors are replaced with ultra low impedance
Rubycon versions, the current to voltage and/or buffer opamps are replaced with the best
sounding versions on the market made by National Semiconductor.
This all brings a nice improvement to the overall tonality and sound staging of the 2ch
output.



If you have the budget for MAXIMUM performance.... Check out the Level 2 mod.
Introduction:

Introducing our tried and true high performance modification packages that will take
your Esoteric unit to a much higher level of performance across the entire audio
spectrum. These mod packages are designed to significantly improve the 3 main
circuits inside the unit: power supply, clocking for servo and DSP, and analog output
stage. Since we have worked on virtually all the models, we have found that the
modifications are just about the same from model to model, hence we have made
these modification packages that will encompass all the models equally.  This mod
package will make your unit (ie: DV50 or DV60) sound better then the other models
above it in the line. Also, if your unit has video capabilities, this will look better as well.
If you already own a Esoteric UX/XO series unit, then this mod package is your answer
to take your unit much further and eliminate the utter need to sell your machine and
look for  something else. We have modified a pretty long list  of the Esoteric units and
all the owners are extremely satisfied and are keeping their unit for the long haul!  We
have 6 years experience of modding the Esoteric Models.

Level 2- "Signature Version"  
Modification Package Descriptions (applies to all one-box player models)
$1800 Total, includes return Fedex ground services, 10 day turnaround


NOTE:
Power Supply Modifications and Clocking upgrade is the same as level 1 mod,
the ONLY difference between Level 1 and Level 2 is the type of 2ch analog
output stage mods. Level 1 is a "parts swap" type of improvement (ie: superior
opamps, voltage capacitors, etc), and Level 2 is a "full rebuild" using ultra fine
quality audio signal coupling transformers or ASi discrete analog rebuild for the
XO-3/UX-3 models, silver wiring and WBT Nextgen Connectors for the best
performance.

-Power Supply upgrades/rebuild-
Same as Level 1   

DEXA D-Clock Reference Clock Upgrade-
Same as Level 1

Analog Output Stage Rebuild using Ultra Fine Quality Audio Signal
Transformers
(Note: Esoteric XO-3/UX-3 players use different mod, look below)
This is a complete rebuild of the stock analog output stage. We can totally redefine the
Esoteric 2ch output sound to create a much larger, livlier and authoritative output stage
with loads of dynamics, speed and resolution. We replace an abundance of OEM
capacitors with the Rubycon Ultra Low Impedance caps. We disconnect the OEM 2ch
analog output stage, and rebuild it using the highest performance I/V opamps, custom
made Ultra Fine Quality Signature Audio Signal Coupling Transformers, and various
amounts of ASi Silver wire is used. The output is true 100% balanced on the XLR
outputs, and/or single ended is done  optimally as well.
Here is the DEXA D-Clock (under 2 picoseconds of jitter!) to
provide much better performance over the expensive Esoteric
G-03X clock, saving you thousands of dollars!
Fully Optimized "World Class" Sounding ASi Modified Esoteric UX-3

This and various other UX-3, XO-3, XO-5, DV-50, DV60 and SZ-1 units done in
recent times have taken quantum leaps over the most expensive single box
esoteric units and other expensive units on the market as well. Great
modification platforms!!

Level 3- "Statement Version"  
Modification Package Descriptions (applies to all one-box player models)
$2300 Total, includes return Fedex ground services, 10 day turnaround


NOTE:
Power Supply Modifications and Analog output stage rebuild is the same as
level 2 mod, the ONLY difference between Level 2 and Level 3 is the DEXA
Neutron Star Flagship clock.  This is the package you want if your looking to
achieve world class state of the art performance!

-Power Supply upgrades/rebuild-
Same as Level 1 and 2   

DEXA Neutron Star Flagship Clock Upgrade-
This flagship clock upgrade will replace the stock master oscillator that feeds the internal
DSP circuitry control chip for the very least amount of noise and jitter possible and the
highest potential of performance that is possible within todays technological limits. With
the Neutron Star installed, the sound is so much more analog that you are detached
from the fact that you are actually playing a CD. Video is substantially improved on
models with that feature. Unprecedented World Class Performance

Note: Esoteric XO-3/UX-3/XO1-D2 players:
Since the design of the XO-3 and UX-3 is single ended only topology and Dual DAC
configuration in the XO1-D2, we have done extensive R&D into which is the best
sounding output stage configuration. We have found that a discrete modified output
stage rebuilt around our standards sounds the best. This
drastically shortens the
output stage for much purer sound. Since the signal coupling transformers are typically
used only for dual differential circuits they will not be used in the output stage mods for
the XO-3 and UX-3. We feel the sound is MUCH better with the discrete ASi rebuilt
circuitry for these models instead added the transformers for these specific units and
the XLR and RCA outputs will still both work together and perform the same.

Now your music is so much quieter, cleaner, clearer, more vivid,more resolute with no
lack of dynamics! Much more music, emotion, and drive over stock. Makes you want to
listen to your CD's instead of your vinyl !! If your using the 2ch analog outputs, you
need this modification to realize the most performance from your Esoteric model!

Esoteric DV-50 Level 3 Analog Output Stage Rebuild
Notice the DEXA UWB Ultra Low Noise Regulators (blue leds),
abundance of capacitors replaced, & signature audio signal coupling
transformers in place to rebuild analog output stage among other
mods performed in this world class rebuild!
I turned the lights down and look at the cool blue led's from
all the DEXA upgraded parts installed. Enough light in there
to light up half of the room!  =)
