Sorry, I have disappeared from audiocircle for a long time, way too busy these days. I will try to get Bob Smith to check in more often.
BDP-93NE - for USA customers, we offer FREE shipping and 30 day money back guarantee. I am certain that if you have the standard 93, after hearing the upgrade board, you won't want to return it. For the price of a few family dinners, you get to enjoy a player that sounded as good as many CDP costing > $5000. Someone compare BDP-93NE with a $15,000 Meridian system and commented that they are so close in performance.
BDP-93NXE - essentially the same design as 93NE, but with re-clocking of all the digital signals for better performance. This is not easy to design, so it cost twice the price of BDP-93NE.
If you want a top quality BDP (93 and 95 has the same video board), and truly world class CDP or DAC (if you use HD for music), go with BDP-93NXE. We are waiting for firmware from OPPO to release 93NE.
BDP-95NXE - this is the ultimate audio player. We will be implementing using multiple high-end DAC chips (we like the sound better than ESS DAC on the standard 95) with re-clocking. This is a non trivial design. Yes, it cost 2.5 times BDP-95, but if it is going to deliver performance equal to some of the best players on the market.
We piggy back on the mass production of OPPO to deliver super high-end performance at entry level price. If we try to make such a machine alone, the volume will be so low that to recoup R&D cost, each unit has to be priced in the 5 figure price range. But now we only have to worry about the R&D cost of the analog board.
