Oppo UDP-205 4K UHD Blu-ray Player is designed for the audiophile and sets a benchmark for performance combining 4K video playback with reference quality analogue audio. This version has been tweaked by Audiocom to offer multizone and multiregion support.
Everyone for whom the theme of high-quality sound and the correct picture from one source is relevant is at least heard of the OPPO BDP-105D Blu-ray Player. This device for the last couple of years was considered one of the most successful for home theater in terms of its functional capabilities and performing talents. However, the massive transition of TVs to 4K matrixes and the emergence of Ultra HD Blu-ray at once pushed the Full HD equipment into the second echelon.
Isolated power supplies for the digital and analogue circuit board practically removes damaging intrusion. The correspondent circuitry is power-driven by an immense toroidal power convertor for greater effectiveness and pointedly inferior external magnetic intrusion likened to the old-style coated steel core.

However, for us the situation is greatly mitigated by the fact that not a single localized film on ultra-high definition discs in Australian stores can still be found. By the way, few people know that some international releases contain subtitles, and sometimes (albeit extremely rarely) even soundtracks in Australia.
But, anyway, and the video content in 4K every day becomes more and more, so that none of the developers can afford to ignore its existence. OPPO Digital responded to the new trend with an enviable efficiency – first with the ultra-high definition player UDP-203, and now with the uncompromising audiophile model UDP-205.
Relative connections of the new player with the BDP-105D are guessed at first glance, even the profile of the metal front panel is identical. The most striking difference is the increased display screen, which is now placed not on the side, but on top of the optical drive tray. And from the front panel, the HDMI / MHL port disappeared, which is absolutely logical – the idea of driving video from mobile gadgets over the wire has long lost its relevance.
The absence of the letter “D” in the designation of the new model indicates the absence of the additional Darbee Visual Presence video processor. In the past generation of players, it was used to improve picture clarity by optimizing it using sophisticated algorithms developed by Paul Darby. Now, the OPPO developers reasonably reasoned that with the advent of technologies like 4K and HDR, the need for expensive artificial enhancers has finally disappeared.
From the back side the devices are almost indistinguishable. Only after looking closely, you can notice the appearance of the two two-fifths of two sockets for trigger mini-jacks and ground terminals.
However, the appearance is deceptive: a pair of USB connectors now conform to specification 3.0, and the Ethernet port from 100-megabit has become gigabit.
A set of two pairs of very good balanced and ordinary linear output connectors remained in the same place as the digital audio ports. The most valuable of them is the asynchronous USB input, which turns the player into a high-end external DAC with support for DSD512 and PCM with a sampling frequency of up to 768 kHz.
The HDMI outputs of the UDP-205 progressed to version 2.0b, more precisely, only one of them, since the second is now designed exclusively for outputting audio streams to a receiver or an external surround processor. About the value of this solution, as well as about many other details of the work of the video path of the models of the new generation, we described in detail in the UDP-203 test. All this information is also relevant for UDP-205, since the video path for both devices seems to be almost identical. Let me remind you that it is built on a custom OP8591 chip, specially developed by MediaTek for OPPO. In fact, this is a quad-core processor with an ARM architecture, in which the hardware level supports a variety of functions for processing ultra high-definition video content, including decoding of H.264, HEVC, VP9 4K and Hi10P streams.
But on the implementation of the sound part, our subject is much closer not to his brother, but to the audiophile progenitor of the BDP-105D. However, the differences are quite weighty in both cases.
The digital path of the BDP-105D was built on the ES9018 DAC – the top representative of the respected, but far from young, Saber 32 Reference line, developed by ESS Technology back in 2008. Last year, it was replaced by new 32-bit SabrePro chips, led by the flagship ES9038PRO, which, as you may have guessed, became the soul of the “two hundred and fifth.” It differs from ES9018 by the separate power supply of I / O, control and conversion units, DSD support over PCM, as well as the presence of a completely new programmable non-linear distortion compensation unit. And ES9038PRO is interesting for a record dynamic range – 140 dB. For the linear output of the UDP-205 itself, this parameter exceeds 120 dB.
The chip is eight-channel, so the developers simply took the second ES9038PRO, and built a multi-channel output on it. Let me remind you that in the junior UDP-203, the analog signal 7.1 is formed by the Asahi Kasei Microdevices DAC AK4458VN.
Another significant difference from the younger brother is a separate linear power supply for analog circuits, built on a toroidal transformer.
The two models use the same OPPO proprietary disk transport, but in our case it is mounted on a two-layer chassis with improved anti-vibration properties. The drive reads almost all 5-inch laser discs of household formats, with the exception of long-rarities DVD-RAM and HD-DVD.
Oppo UDP-205 – Advanced Imaging
Oppo UDP-205 4K Ultra HD uses a dedicated 4K UHD Blu-ray decipherer System on Chip with the quad-core OP8591, which bids the most supreme progressive image decoding and processing knowhow accessible.
Reference 4K Ultra HD
4K UHD format enables HDR video and an expanded colour range for more natural and realistic colours. HDR10 provides an accurate HDR to SDR conversion for older displays. Oppo UDP-205 4K Ultra HD augments lower res videos to the 1080p resolution of a Blu-ray disc (which is 4 times larger) to a compatible screen. Support for Dolby Vision will be available in the future via a firmware upgrade.
Reference Level Audio
Reference level sound is provided through the analogue outs and increased power of the built-in headphone amp. A dedicated, high-precision HDMI audio clock significantly reduces jitter and eliminates timing errors allowing you to enjoy your music with increased accuracy.
Armed with double ESS ES9038PRO 32-bit HyperStream DACs, Oppo UDP-205 has finest in class 140dB dynamic range for both stereo and 7.1 channel analogue audio.
4K UHD Playback
It’s able to play media files, 4K UHD Blu-ray discs and user generated content. Backing for decrypting the HEVC, H.264, VP9 4K, and Hi10P video codecs is supplied. Oppo UDP-205 4K Ultra HD enlarges subordinate res data up to 4Kx2K at 50/60Hz to a suitable display, four times the resolution of 1080p Blu-ray disc.
High Dynamic Range
One exhilarating portion of 4K UHD arrangement is the addition of HDR video and an extended colour variety. HDR10 format is also skilled in delivering an exact adaptation from HDR to SDR for older displays. Provision for Dolby Vision will be obtainable via upcoming firmware advancement.
Alterations can be applied to hue, saturation, brightness, contrast and sharpness reimbursing any boundaries initiated in other home theatre equipment or just to match your own individual taste.
4:4:4 Colour Space
Oppo UDP-205 4K Ultra HD reserves all current SD, HD and UHD resolutions counting 4K@60p, 4K@50p, 4K@30p, and 4K@24p by means of several colour spaces such as PC RGB, Video RGB, YCbCr 4:4:4, 4:2:2, and 4:2:0.
