Extracting high-quality audio from Blu-ray players can be problematic in that the HDMI signal format interleaves video and audio data into a single transmission medium. While a convenient means of transferring A/V data between components, the process of combining these signals invariably imparts a level of digital jitter to the audio data sometimes as high as seven nanoseconds. For the purpose of comparison, a good CD player's jitter specification is in the picosecond range, i.e., three orders of magnitude less. In practical terms, it is difficult to decode HDMI audio without employing extensive re-clocking circuits, thus inflating the cost of a good HDMI audio pre-processor.
The simplest, most cost-effective way of dealing with the analogue audio issue is at its source. And this is what Nuforce have accomplished in the Nuforce Edition BDP-93NE and BDP-93NXE. By replacing the analogue output circuit board with a proprietary design, the 93NE and 93NXE delivers the highest possible levels of the natural, beautiful sound that has long since established Nuforce’s enviable reputation. We’ve every confidence you'll agree that the Nuforce BDP-93 Extreme Edition equals or exceeds the performance of the world’s best digital audio disc players.
The OPPO BDP-93 Nuforce Edition player and 93NE upgrade board features:
All 8-channels have been re-engineered to deliver ultimate audio performance.
On-board linear processing circuitry delivers highly regulated and filtered DC power to all analogue output stages for lowest noise and distortion performance.
Output stage designed to avoid the need for a signal-degrading muting circuitry.
Advanced analogue filters eliminate phase shifting within the audible bands.
High performance op-amps for a warm, vibrant, seductive sound.
A special 'minimal phase shift filter' is used in the audio band to preserve the best sound quality. This filter has a gentle roll off curve to minimize phase shift. FR spec: +/- 3dB from 15-50kHz.
Supported sample rates: 44.1, 48, 88.2, 96kHz, 192kHz, 16-24-bit
The 93NE board's sonic goal was for 12AX7-type triode characteristics without tubes.
