Our Oppo BDP-83 Blu-ray player improvement mods are extensive, and the results are well worth the costs.
Many machines have now been completed. We continue to customize these even though they are no longer made.

These improvements in the
performance of this great Blu-Ray player are brought about in the now
unified modifications...
The "Full Force".
We dropped the basic as nobody *only wanted* the basic, so it is just a
part of what has now become a set of complete modifications, depending on the machine.
Here is a description and pictures of what to expect.
These are pictures of the stock audio board as it comes out of the player.
..
We replace the two prong AC inlet with an immersion LN² cryogenic treated grounded version
inlet, and properly ground the chassis, both as a safety issue, and
that it turns the metal chassis into a proper Faraday shield that keeps
noise out of the chassis rather than leaving it a floating antenna that
takes in RF and transmits it to the electronics inside.
We replace the
AC fuse with a superior high grade circuit breaker, which eliminates the FM
distortion and higher power-line impedance that the fuse creates. (# 1 in picture below) We
replace the AC wire with our JENA Ultra-Wire that has lower graininess in
sound than the stock wire. (#2 in picture)
Picture of the AC power board modifications (#1 #2 and #3 in picture below)
.
We take the power supply's as shown below (different versions and
variations) with JENA Ultra-wire leads and ultra fast and ultra low
noise Schottky's Diodes are installed:
.
And they get our anti-ring treatment...
Explanations of the science of this found here: Q&A
.
We replace the 3 rectifiers that feed the analog board with real
Schottky's parts (#3 in picture above)...this reduces avalanche noise in this delicate voltage
position. We add high speed bypass caps to the final filters that feed
the analog stage on the power supply board.
On the analog board we add about 30 parts. The stereo out jacks are
replaced with immersion LN² cryogenic treated Cardas jacks with JENA LABS
Ultra-Wire hookup. The op-amps are replaced the latest National
Semiconductor LM4562 parts. The output of the stereo set is direct
coupled eliminating the caps in the signal path. The final filter
electrolytics at the stereo set are removed and replaced with the best
possible, the Elna Silmic II silk paper electrolytics. Some of the
small value bypass caps on the audio board are removed and replaced
with current generation ultra fast monolithics, as well as almost 20
more of these being added to bypass the remainder of the electrolytics
and poly caps on the stereo section of the audio board. If the
multi-channel output is to be used, we will do the same op-amp upgrade
and direct coupling, and power supply improvements to the multi-channel
side of the board as well.
All the ICs on the audio board are treated with Silent Running® Audio
dampening material. The main mother/video board has ALL of the ICs,
crystals, inductors, and the digital video output jacks treated with
Silent Running Audio dampening material. The bulk of the chassis and
the cover is also treated with a combination of Silent Running Audio
and Cascade Audio Engineering® Vibration Blocker 2 damping
materials. Q&A

Back of modified Audio Board.
The DC power filter we designed and built for these audio and video boards is called the Full Force.
It replaces the original harness that was there which was unfiltered for both boards.
More information below about this significant enhancement.
We suggest the base model 83, not the SE which is more expensive...The
DAC is slightly better on the SE, but the analog stage that follows it
cannot be made as good as the less complex analog stage in the regular
edition. We have BOTH here, and modded the audio boards boards to the
same extent, and the standard version IS the musical winner, at least
after we do our re-engineering. The SE board requires 3 dual op-amps
after the DAC and it cannot be reduced. The standard can be direct
coupled and use only 2 dual op-amps, and employs a less complex path
for the signal to be damaged in.
NEW...
We also replace the economy feet with our damped product All Current Modified Players come with our latest compound rubber + density filled design.
Great feet for your BDP-83.
Notice that we treat the base plate of the player with antivibrational VB2 and that we leave the ventilation ports intact.
.
We use 6-32 stainless button head hardware to securely fasten the new feet to the base of the player.
We developed these for our Platinum Power Conditioners... They work very well.

"Full Force" mods include...
..
Above right is the actual Full Force Bipolar DC Power Filter in current production.
Inside of the above player are the Full Force power filters (2 types.)
JENA Labs designed this compound filter to feed the audio board with REALLY low noise DC power.
The second power supply filter is seen. (Full Force filter#2)
.
We do attach a special JENA LABS nameplate to the
front of the player, signifies that the mods are genuine and that you
own this great machine.
Detail of anti-ring fin treatment to main board. IC's now get VB2 and cap's get SRA anti vibration material respectively
No-one in the business does such a comprehensive rebuild for this low a
price.
"Full Force stereo" (Bipolar DC power filter for audio board and video board) - with all else included $1100.00
If you DO
select the SE edition of the player, the cost is $1125, because of the additional
op-amp replacement costs.
"Full Force *SE version BDP-83-SE player" (Bipolar DC power filter for audio board and video board) - with all else included $1125.00
Plus shipping and insurance added which depends on your location.
