This is our fully modified Oppo UDP-205 player including 7.1 rebuild. There
is no other modifier in the world who does such mindblowingly precise
applications of so much exotic EMI/RFI shielding, resonance control and
circuit rebuilds with many upgrade options like we do here. If your looking
for the best sounding & performing Oppo 205 mods in the world, this is it!
This pic is of a 100% STOCK Oppo UDP-205 for comparative
purposes, please look back and forth between this picture and
the picture of the modified 205 above it, night and day!
All modified units owners are sent pictures before shipment.
This is a pic of one of our modified 205's with the power
supply lid off and the 7.1 channel board pulled out so you
can see the rest of the modified unit.
This pic is of the USB and Analog stage. You can see the
XLR and signal transformer we fabricated into the rear panel
for the AES/BEU input upgrade. The analog board has been
fully modified and you can see 5 tweaked Bybee Music Rails
to drastically lower power supply noise on the modified
power supply that feeds all those modified circuits.  
5 Bybee Music Rails  (DC power supply noise reduction
circuits) that are tweaked out and coated with C37 Gold
Standard and the precise application of Audio Magic
Ultimate Black Out paint on eveything for ultimate
shielding/resonance control.
This is our 7.1 channel rebuild mod pic. After doing alot of
customization, we can fit 8 high end tweaked out custom ASi
signal coupling transformers across the 7.1 circuit board. This
unit also has 8 WBT Nextgen copper upgrade tweaked out
connectors for the whole package!
As one of the upgrade options, we add 2 Bybee iQSE panels to
the Oppo 205 power supply and one as shown here mounted
on the shielded top lid over where the power transformer is to
quiet down that area of the player.
Here is a rear shot of the fully modified player. Please notice the 7.1
WBT nextgen RCA upgrades (with Audio Magic Black out paint RF
screen mask precisely painted over all connectors and rear panel for
extreme RF control). There is also a AES/BEU XLR input added.
Before (stock) & After (modified) pictures:
This is a before and after pic of the 7.1 channel circuit board rebuild showing
you how drastic it is. The bottom circuit board is the 100% stock 7.1 circuit
board and the top circuit board is the fully modified 7.1 circuit board with 8
high end tweaked ASi custom signal coupling transformers for the best
sound.  You can see the Audio Magic Black Out paint on all the parts.
The pic to the right is another pic of a 100% stock oppo (top) in
comparison to the fully modified oppo 205 (below) it.  This pic has the
units 7.1 channel boards and power supply shells removed to show
you the power supply underneath and modified parts.
Here is the shielding shell lid that fits over the power supply
inside the Oppo 205. The left lid is 100% stock and the right
lid has been completely shielded on both sides and a Bybee
iQSE panel has been mounted to clean up noises inside the
modified power supply section of the Oppo.
The other side of the shielding shell lid to show you
the difference between stock (left) and modified (right).
Everything is heavily shielded!! No other modifier shields like how
we do with multiple kinds of precise shielding done throughout.
This is the left side of the player with the shielded power supply lid
and shielded power supply toroid transformer and wiring.
