"High Performance A/V Modifications & Products"
Introduction:
The long anticipated Oppo DV-983H Universal Player is now here! This MSRP $399 unit
utilizes the optimum Anchor Bay VRS video processing circuitry for stellar upconverting
standard definition DVD playback performance. High Definition video formats (ie: HD-DVD &
Blu-Ray) are not supported. Our ingeniously engineered & professionally installed
modifications provide a level of reference level quality of sound and video that is just not
found anywhere in the standard definition DVD marketplace today. We can confidently
state that this is the best looking standard definition digital playback source we have
experienced to date!
How does it sound and compare for the 2ch audio enthusiast? Comparing the ASi Modified
DV-983H W/D-Clock to the stock DV-983H is pretty remarkable. The stock unit has a
compressed and dynamically limited sound to it in comparison. The soundstage sounded
like it was mostly trapped inside the speakers. The clarity and definition was just not there
compared to the modified unit. Amusical is the term that comes to mind on the stock vs.
modified DV-983H. A quick and easy A-B proves the modification makes for a real world of
an improvement! This DV-983H really breathes... it sounds wide open, spacious, very
musical and balanced from top to bottom with no exaggeration in any specific frequency
bands! How does the ASi DV-983H W/D-Clock compared to some pretty expensive stock
digital sources on hand ($2000-$9000 units)? Well, first the stock DV-983H does do a
decent job against other stock units that are seriously more expensive. No doubt about it.
With the ASi DV-983H W/D-Clock we immediately heard a greater sense of resolution,
music sounded free flowing into the room with great presence and control, we had a much
larger, wider, deeper soundstage, with exceptional crystal clear vividness in voices, with
great separation of instruments and refinement of brushes and cymbals and great
dynamics. This player is truly a dream come true for the standard definition DVD player and
universal audio format enthusiast!
Note on New Modified Unit orders(7-9-2008):Units are sparse at this moment, maybe
1-2 max units I can get, please email before ordering. Once the unit is in possession, they
take 7-10 business days to build, test and ship out. 1 Year full warranty!

Oppo DV-983H Modification Descriptions & Prices
Modification Package Descriptions
Upgraded IEC Connector for better grip onto power cords-
We add a high quality IEC connector that is cryo-treated to the rear of the chassis for use
with high performance aftermarket power cords. The reason is the stock connector doesn't
grab and bite onto some power cables that well and they can fall out, this upgrade will
ensure a tighter fit. We also correct the backwards polarity wiring issue in the stock design!
NOTE: The stock connector and supplied AC cord with the DV-983H is a 2 prong version.
You need to supply a power cord for the unit. We highly recommend using an aftermarket
power cord for improved sound and video, it truly deserves it
Ultra Low impedance Rubycon capacitor replacements-
We replace an abundance of Switch Mode Power Supply and DSP/Analog board voltage
rail decoupling capacitors in all critical areas of the player to the ultra low impedance
Rubycon capacitors! We also replace the OEM main SMPS reservoir capacitor with a new
special low impedance version that allows for substantially more storage and filtering.
Very Nice improvement! A HUGE change in total sonic tonality and character and as well
as providing the video section with substantially less noise for cleaner output. The stock
capacitors are very poor in comparison of the factors of impedance and ripple current &
will not let you realize the full potential of this unit!
Ultra High Speed Diode Bridge-
We replace the stock noisy/glary/grainy rectifiers with very low impedance ultra fast
rectifiers. These are absolute superior to the stock diodes rectifiers, removing the glare,
grain and grit from the sound and video and allowing you to realize a much cleaner audio
and video performance! !
Qty: (3) DEXA UWB (Ultra Wide Bandwidth) Ultra Low Noise Voltage Regulators-
The UWB Regulator is a high end replacement to the OEM 7805 +5vdc, OEM 7812 +12vdc
and OEM 7912 -12vdc voltage regulators used to regulate DC voltage in the Oppo.
Unfortunately the OEM 7805/7812/7912 regulators have very poor noise performance.
Especially if there are external noise sources around the OEM regulators, like ripple or
load fluctuations. In comparison to all the OEM regulators, the UWB's have more than 100
times better ripple rejection, 10 times lower noise, and no line and load regulation error.
The result is a drastic improvement across the entire spectrum and more dynamic range.
2ch Analog Output Stage Rebuild-
We delete the OEM Analog Output stage after the DAC Chip (all capacitors, analog
filtering, opamps, etc) in favor for our optimized version using the very best sounding
opamp on the market feeding the new 2ch analog output jacks, bypassing allot of stock
circuitry. We replace the OEM capacitors with Ultra low impedance Rubycons. We feel that
this minimalist approach will most likely be of higher resolution than if you compared it to a
outboard DAC. (The factors of connectors, coupling caps, digital cables, impedance, input
receivers, filters, stock electronics, etc.. come into play in the outboard DAC)
High Performance RCA Connectors for 2ch out-
We add a set of very high quality Vampire RCA jacks for the 2ch output section to vastly
improve the signal integrity over the stock jacks!! These are wired via Silver Wire from the
optimized 2ch output section
HDMI Video Output Board Modifications-
Replace OEM capacitors used for critical voltage decoupling and storage in the areas
around the ABT Scaler/Deinterlacer chipsets to the Ultra Low Impedance Rubycon
capacitors for a substantial improvement in video performance.
Internal Soundcoat Damping-
Apply Soundcoat damping material to specific areas to minimalize the amount of internal
vibrations and ringing.
E-A-R Specialty Composites Vibration Isolation Feet-
E-A-R Specialty Composites is a leading manufacturer in the high performance vibration
isolation and damping material industry. We add a trio of their vibration isolation feet in
specific areas on the underside of the Oppo unit. There is essentially no OEM feet and this
gives the unit a much more stable stance as well as controlling vibrations at certain critical
points to enhance the performance of the unit in a whole.

DEXA D-Clock Reference Clock Upgrade-
The OEM Oppo 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
DVD playback. The ultra-low jitter and noise performance of the D-Clock immediately
releases impressive sound quality from the Oppo DV-983H & 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!

7.1ch Analog Output Stage Rebuild-
We delete the OEM Analog Output stages for the Multi-Channel outputs after the DAC
Chip (all capacitors, analog filtering, opamps, etc) in favor for our optimized version using
the very best sounding opamps on the market, bypassing allot of stock circuitry. We
replace the OEM capacitors with Ultra low impedance Rubycons. The modified outputs are
rewired to the now isolated RCA outputs on the rear since there isnt enough room to mount
new jacks for all signals. This mod will now enable you to have a completely modified ASi
DV-983H with all analog output channels modified to enjoy your multi-channel music or
movies! ALL ANALOG OUTPUTS IN THIS UPGRADE ARE MODIFIED THE SAME WAY
AND WILL HAVE THE SAME QUALITY SOUND FOR STUNNING MC PERFORMANCE.

Doug is extremely
professional,reliable,easy to
work with,and great to talk
with. I got his fully modded
Oppo 983 and the work is
top notch. The performance
of this player is incredible,
even right out of the box.
Awesome job! Thank You!

I received my ASi Oppo
DV983 and have run it in for
about a week and all I can
say is I am blown away with
the sound & the video is
very film like. I own a non
modified Esoteric DV50S
and the modified oppo is
clearly and significantly
better across the board for
audio and video. A job well
done by Doug and ASi ! Get
one of these, you wont
regret it!
