50% non-refundable deposit is required to reserve a start date and finalize order. Remainder due upon completion, prior to shipping.
Return shipping is not included in the mod price.
We do not supply the Oppo-95 players. You may order from Oppo and have units shipped directly to us. Retail price for Oppo 95 player (stock): $995.
Stock player is switchable – 110V/220V – we can build our external supply for 120V or 220-240V.
Region Free upgrades are available for $250, installed (when included with our modifications). This will allow a player purchased in the U.S. to play all regions of DVD, DVD-A and Blu-Ray discs.
I just can’t believe how nice the player is already sounding (and only with about 10-15 hours on it on my end). My friend came over yesterday and had to pick his jaw up off of the floor. It has really been a pleasure going back through my somewhat neglected CD collection and listening to things all over again. Many thanks! I think the try strengths of the player over stock are the wide soundstage, the clean and clear highs, the tight and detailed bass and the extremely low noise floor. The dynamics are pretty much off the charts as well. My wife is really enjoying it all as well—a major bonus! Ya done well, man… - J. Strid – May 2, 2011
Obviously the advantage of the 95 is that it plays all formats and has great video too.
Another advantage to the Oppo 95 is its USB (24/192) and eSATA data interfaces. This allows for music stored on external HD or other USB or eSATA compatible storage device to feed music directly to the Oppo. This does require a monitor be connected to the player to show track listings, etc.
The Oppo Tube Mod for the 95 includes the following:
- Removal of all feedback-based op-amp analog circuit.
- Direct coupling of DAC output to ModWright’s I-V circuit.
- Direct coupling of I-V circuit to ModWright’s fully balanced 6SN7 based Class A tube stage
- Top quality parts throughout, including MWI capacitors and Takman Japanese carbon film resistors.
- External tube-rectified high-voltage tube supply powers ModWright tube analog stage.
- Optional ‘Truth’ umbilical between external tube supply and player provides clean and pure DC power for improved detail, dynamics and soundstage.
- Upgrades to stock digital power supplies for lower jitter and less digital edge.
- Enclosure and drive vibration damping for lower jitter and less digital glare.
- 5AR4 tube rectifier and 6SN7 driver tubes allow for broad range of tube rolling, to obtain the right tonal balance for YOUR system.
Recommended Tube Upgrades for the Oppo BDP-95 Mod:
- Output Tube: Sophia Electric 6SN7 – Galen Carol Audio
- Rectifier Tube: Mullard, Amperex or Phillips ‘GZ34’
Sonics benefits of the tube mods: A fuller, richer midrange and even more extended highs and expanded soundstage. Bass is extremely deep and well defined. The overall presentation combines midrange warmth, broad bandwidth, sparkling detail and resolution, WITHOUT the common aggressive edge and glare found in lesser digital components!
The lack of feedback (inherent in op-amp based analog stages) and the clean and simplified signal path of our 6SN7 tube-based circuit with tube rectified external power supply, simply lets the music through.
The ModWright Oppo 95 tube mod IS superior to our previous tube mod for the BDP-83SE.
Results of listening tests of tube-mod Oppo 95 and stock Oppo.
Both on redbook CD and DVD-A, via RCA outs only so far. Same cabling used and same system.
We happened to have a pair of KWA 150 Signature Edition’s running in mono to my Daedalus Ulysses. Preamp was LS 100.
Using same cables, compared a stock Oppo-95 to the tube-modified proto Oppo 95.
What jumps right out at me is the increased soundstage depth and width. Secondly, the low- level information and aural cues are simply much more apparent with the modified unit. Detail and resolution excel with the modified unit, over stock, and stock is GOOD!
The key differences are resolution, micro-detail/dynamics, decay and a natural ‘ease’ to the music.
Sonics benefits of the Solid State mods:
The solid state mods include replacement of the first stock op-amp stage with our own discrete circuit. The second and final gain/buffer op-amp stage is biased properly and revised for optimized sound.
In addition to the power supply upgrades and damping mods that are included in the tube mods, we also upgrade all key signal path resistors to Japanese carbon film resistors.
The end result is a clear improvement over the stock player, ridding the music of digital edge and glare and providing a significant improvement in overall musicality. The lower noise floor and cleaner signal path allow for a broader soundstage and greater refinement of overall resolution and detail. This is due largely to ridding the circuit of one entire op-amp stage, as well as upgrading the signal path resistors and improving the remaining op-amp stage.
We offer the SS mod as a less costly alternative to the tube mod and offer it as both a 2CH only and a 2CH and MCH option, in which case both stereo channels and all eight of the multi-channel circuits are upgraded in the same way as the stereo channels.
