This OPPO has all original everything, double boxes, packing, remote, original PC and HDMI cable, manual, bag...The mechanical condition is excellent, I've never had a problem or a hiccup. The cosmetic condition shows some light wear on the top and one side, otherwise excellent. I am the second owner, but like a lot of us, I have switched to streaming music and no longer need this. This unit has a combined 2070 dollars of modifications between the ModWright and NuForce companies, in addition to the 899 cost of the standard machine. 1295 for ModWright + 200 for balanced out by ModWright + 75 for ModWright hardwired fan + 500 For NuForce Mods, please see pics for modwright receipts.
The ModWright mods include these per ModWright via e-mail Customer Service as the 83 SE is no longer on their website.: -
"2-Channel Solid State Mod ($950) Upgrade of stock power supplies. Burson Clock upgrade. Installation of proprietary, dedicated analog power supply of our design. Upgrade of Stereo Left and Right analog channels only with our discrete FET-based circuit. Damping mods to chassis and drive. - Multi-Channel Solid State Mod ($345 additional) to include them in the discrete FET-based circuit modification above."
"- Upgrade of Stereo Outs to Fully BALANCED - XLR Connections ($200)
Later on, he (the original owner) sent it back in to have the fan hardwired in. I am not sure why we did this off hand but I believe is helped with noise from the fan."
From Dan Wright via a separate e-mail:
"The XLR outs are fully balanced. The unit does use four DACs per channel for Stereo playback, but the output from the four DACs is still differential - i.e. the output is +/-L and +/-R. We use four channels of our mod board to allow for both +L, -L, +R and -R. The remainder of the channels are for FL, FR, C, SL, SR. The RCA's are wired from the XLR +, so that both XLR's as fully balanced outputs are available as well as in-phase RCA's."
In regards to the mods by NuForce:
Nuforce worked in tandem officially to use the Special Edition as a base to build upon.
~upgraded audio section:
~a better power supply: The original BDP-83 has a single +14V rail that is shared by the analog audio section (+/-14V) and the BD loader (regulated to +12V). The SE now has a separate +12V rail for the BD loader, isolated from the dedicated +/-14V rail powering the analog audio section. The SE audio board also has additional linear regulators to further smooth out the power and to provide enough local reserve current for better bass, according to Oppo.
~upgraded DACs (ESS Technology ES9016 4 DACs per channel vs. Cirrus Logic CS4398 1 DAC per channel) and increased frequency response (up to 44kHz at +/-0.2dB)
dedicated stereo output uses another 8-channel Sabre32 Ultra (ES9016) DAC chip by stacking 4 DACs for each of the Left and Right channels to achieve even greater audio performance
~Replacing critical analog components with the high-grade equivalents NuForce uses in its high-end audio components:
Superior high-speed power regulation on both DACs and all analog power rails. Improved power supply regulation also applies to the 7.1 channels
High-performance parts and related circuits/component values replacing the stereo channels’ monolithic devices.
Bypass the Stereo and 7.1 channels’ output muting circuits. The SE’s relays are better than the standard BDP-83’s muting transistors.

Sorry, no trades. The price includes PP fees and shipping. I will only ship to the lower 48 states (CONUS). Please spend a moment to review my feedback and purchase with confidence!
