At this point I would consider Lexicon and Theta as modders as well as the aftermarket companies like Modwright, AsiTek and EVS. The distinction between the manfacturers is aftermarket modders atleast are giving you an idea what they are replacing from the oem Oppo parts.
I like Theta products very much, but again from the looks of some of the internals shots as well as the soundstage article, the power-supply seems to be the only thing that has been changed, atleast Theta gives us that, (On a side note I am kind of suprised Theta didn't come out with with a Bluray player based on a Pioneer platform, considering their long time use of their pioneer based players and transports) whereas Lexicon seems to make more ambigous claims of all the re-engineering that their team has done.
This is what Lexicon claims they have done to re-engineer the OPPO:
“What are the differences to the OPPO?”
When we specified the BD-30 we focused on premium video & audio performance, fast response times
(*1) , and a mechanical construction that upholds the lexicon tradition of excellence
(*2) – Some parts are similar to the OPPO due to the fact we purchase subassemblies from the same contract manufacturer. We then ship this subassembly to Indiana and complete the manufacturing in the States. We load in application specific firmware
“why does the Lexicon cost more?”
The BD-30 is the highest performance blu-ray player available today and when you see the unit, you’ll realize that the product not only is the highest performance player, but is build to the highest standards in the USA. It is then shipped with Joe Kane’s setup disc
(*3) and supported with world class customer support
(*4) "
(*1) Faster load times that the stock Oppo...Ok, that will be interesting to see, Surely not worth the +$3000 price hike
(*2) Hmm, Ok a thicker aluminum faceplate, still looks to be a steel chasis and same the Oppo feet.... maybe less resonance in the chasis with the use of the aluminum and a stonger chasis and probably tipping the scale at +30lbs
(*3) Oppo ships the S&M and AIX calibration Disc, what is Lexicon's point other than marketing and name dropping of a respected individual in the A/V community?
(*4) No way, Lexicon can even come close to Oppo's level of Customer Service
I think the only weak link for people that are craving a little more performance out the stock Oppo- is within the OPPO analog IC. These manfactuers don't need to necessarily swap out the DACS (they are quality DACS), but the analog circuit needs some reworking as well as the removal of some parts (i.e. opamps)
