OPPO BDP-83SE - Nuforce Edition 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. Nevertheless, imposing as little as possible along critical signal paths is clearly preferable. The result is a better power supply and optimized analog signal paths. As always, the proof is in the listening. The improvements in stereo (CD, SACD, DVD-A, BD Audio), and L/R/C movie outputs are clearly audible.
