MEASUREMENTS: Oppo UDP-205 DSD Playback (DSD64-DSD512), and PCM 768kHz. Plus CES2019 coverage thoughts...


Alright guys and gals, it has been months since I completed the set of measurements of the Oppo UDP-205 last year (here, here, and here).

In early December, David M wondered how the Oppo performed as a DSD player as I had neglected to measure that.

Over the years, I have measured DSD output performance but remember that this is a little bit of a pain :-). To obtain some results for comparison with PCM in RightMark, what I typically do is take the test signals (originating in 24-bit PCM), convert to DSD using software like Weiss Saracon, and then play back the DSD file through the DAC into the ADC which of course takes that analogue output resampled back into PCM for analysis. Doing this understandably adds other variables to the measurement system which should still be minuscule. Over the years, I have looked at things like PCM-to-DSD converters (here and here) to demonstrate that the conversion programs do have an effect as one would expect with different resampling and modulation algorithms.

A Look at the Oculus Rift Touch VR System! (And the Oppo UDP-20X gets a firmware upgrade for HDR10+.)

Happy 2019 everyone!!!

It looks like Archimago was a nice boy in 2018 :-). Look what Santa brought him under the Christmas tree:


The Oculus Rift + Touch VR Bundle runs very well on that Intel i7 / nVidia GTX 1080 computer I have in my sound room.

As I mentioned last time at the end of 2018, I don't use the "man cave" just for 2-channel music listening (I think instead of calling it a "sound room", I should rename it my "media technology room"). Today, I'll just share a few thoughts on this device. While this isn't the usual stuff I talk about around here, I think it's good to look outside the audio hobby regularly and consider all the things the modern media technology hobbyist can do that vie for one's attention and time! VR being one that's still IMO very much in its infancy...

MEASUREMENTS: Oppo UDP-205 Part 3: Jitter, some conclusions, discussions, and suggestions.


We've reached the last of the "trilogy" measurement posts I'm planning to make on the Oppo UDP-205 (at least for now!). We've already examined some "microscopic" measurements like the oscilloscope reading of square waves, talked about the filter settings and relative differences. Then we've looked at the RightMark measurements demonstrating excellent low noise level, low distortion readings, good frequency responses, and minimum crosstalk across the different outputs.

With this post, let's have a look at the J-Test results from the various outputs to make sure there are no issues, and of course in the process examine temporal stability with the various digital inputs including USB, ethernet, S/PDIF, HDMI, and of course as a CD player. We will then close off with some general thoughts, suggestions, and opinions around this device and broader about the features that might be worth pursuing in audiophilia.

MEASUREMENTS: Oppo UDP-205 Part 2: Frequency Response, Noise and Distortion Levels. (Plus a look at the new v60 beta firmware.)

Let's continue today with the measurements of the Oppo UDP-205 as started a few weeks back when I looked at the digital filter settings and output levels for this device.

As promised, this time we're going to dive into some RightMark measurements of this device looking at the quality from the different analogue outputs, whether the digital inputs make a difference and we'll even explore a little around multi-channel.

As I noted in the preview, this device is based on the ESS ES9038Pro DAC, currently the "top of the line" reference DAC available from ESS. The results here I think would be interesting by providing comparisons with other DACs such as with the previously measured Oppo BDP-105.

MEASUREMENTS: Oppo UDP-205 Part 1: Output levels and digital filter settings... (And a few words about recent Munich 2018 MQA interview videos, McGill listening test out.)

Well guys, with this post, I'll begin a multipart look at the Oppo UDP-205 4K Blu-Ray player as an audio component "more objectively". Clearly, as I presented in the preview a couple weeks back, the UDP-205 is very much a device created to appeal not only to videophiles but audiophiles. Why else would Oppo go the extra mile and use dual "reference" ESS ES9038Pro Sabre DACs, provide 2-channel asynchronous USB 2.0 input, both multichannel and stereo analogue outputs plus balanced XLR? It even provides a secondary HDMI 1.4 "audio" output for lower jitter to an external DAC compared to the higher spec HDMI 2.0 which is of course a necessity for 4K/60fps/HDR video; something that I have not seen before. IMO, for home video purposes as a 4K player, the UDP-203 would in fact be very much sufficient - the upgrades found on the UDP-205 are primarily for those who want elevated audio performance. We'll look at whether this is true through these objective measurements.

For the post today, let's start with a few of the "microscopic" measurements that I typically put devices through. The reason I'm breaking measurements into multiple parts is because there are so many ways you could use this device! You could spin disks and make this a CD/DVD-A/SACD/BluRay-Audio player. Hook it up to a streamer/computer through the USB 2.0 interface. Use HDMI input for multichannel audio decoding. Of course it could be used as a S/PDIF DAC with TosLink or coaxial inputs. How about use it as a DLNA/UPnP streamer (works fine with JRiver, even 5.1 multichannel FLAC)? We'll look at bits and pieces in the performance of this device over the next while, concluding in a general assessment of quality and shortcomings once all is said and done...

A Look at the Oppo UDP-205 & The Great Audiophile Debate AK vs. JA of 2005.

Oppo UDP-205 and Black Panther.
Although I have already collected quite a bit of objective testing results from the Oppo UDP-205, I have not had the time to analyze the data or constructed the graphs and charts due to time constraints. Rest assured, the number, graphs, and charts will come :-).

At the time of this writing, I see that while the UDP-205 is in very short supply if even available any more (excluding the speculative price gouging on eBay of course), the UDP-203 is still available.

Today, as a start, let's just spend some time talking about this device and the features. By now there's no mystery since reviews over the last year have been thorough such as from TechHive and Audioholics. Oh yeah, even The Absolute Sound put in a review. In fact, the Audioholics review provides some excellent data on the performance of the Oppo UDP-205 versus its sibling the Oppo UDP-203.
