OPPO 103/103D Mods
2-14-2014: Oppo has done it again....raised the bar. The new 103D has better picture and sound via HDMI (even without the Darbee processing). We have changed all the caps in the new power supply to lower impedance ones for better performance and also have added cork damping under the power transformer and are now damping the main processor heatsink (all for better audio and video).
The two mods available for both the 103 and 103D are:
1. HDMI/Digital out mod: We change the switching power supply to a linear power supply, modify the transport, remove the toslink connector, install a super low jitter clock on the main processor using our custom shunt regulator and install the $400 AudioMagic Pulse Gen ZX. This mod makes the picture, the HDMI audio and the coax out much much better and also makes the 7.1 analog out better. $1050. We can also do the mod without the AudioMagic Pulse Gen ZX. Call for pricing.
2. Analog output stage mod: We replace the entire output stage in the front two channels with our own zero feedback fet buffer circuit. This gives one volt RMS per phase. We also add a WA Quantum dot to three power supply caps and one to the DAC chip.....also damp the heatsinks on the regulators. An additional $200. This output stage makes the two channel outputs sound even better. Really great sound now. This mod is available only in conjuntion with the above mod. Not solo. You really need to clean up the transport and jitter to get the analog out to sound really great.
If you only are using the Oppo for its digital/HDMI outs then the modded 103D is the only way to go. The 105D has the same digital out/HDMI out capability.....you get the 105D cuz you want the super duper analog out capability, direct DAC inputs, headphone amp and better digital volume control..

RIC , I am still amazed at the difference in the audio and video after your Mod.
I compared my friend's un-modded 103 to the Tweak audio digital mod and the Modded diff was significantly better.
THANKS again and have a great New Years.
Way better sound using the new linear power supply. Check out the size of that tranny! We mount the transformer on cork and tie it down with cable ties....much better sound than using a steel plate and screw.
Ric, thanks, your mods to the 103 are outstanding! Got the power supply mod, too, and am using the 103 as a transport. Resolution, inner detail and presence are all WAY better than the stock 103, even though I did not opt for the Pulse Gen mod. Also the bass firmed up and deepened. Highs are clearer and applause is very realistic sounding. Really sounding awesome now...for me the transport really IS roughly half the sound quality...(!) Thank You! Best wishes

Just listened to my Oppo with LPS installed and after 100 burn in on XLO track. Sounds very good, more dynamic, smoother, more articulate.
Ric Schultz at Electronic Visionary Systems did me a big favor recently by installing OPPOMOD's Linear Power Supply in my modded Oppo 103 (modded by Ric earlier in the year). In addition Ric upgraded the stock caps in the LPS and provided a better physical interface for the big honking toroidal xformer in the LPS. Mods Ric provided for the Oppo 103 include Audio Magic Pulse Gen ZX, analog and digital mods, damping for chassis, caps and transport, etc. In addition to Ric's mods I have incorporated a few of my own, including WA Quantum Chips, Marigo VTS Dots, Golden Sound Acoustic Discs, Moingo discs for transport, tray masking, Leaf Green Cream from PWB, Quicksilver Gold Contact Enhancer, etc. Thanks to Ric for extraordinary sound in terms of dynamics, realism, articulation, and air. The Oppo drives a Bada Hybrid SET headphone amp with naked Sennheiser 600s. Cabling by Analysis Plus and Nordost. All power cords burned in on Alan Kafton's latest Audiodharma Cable Cooker and all cabling cryogenically treated. More analog than analog.

Thank you for the great job modifying my Oppo 103.
