My Yamaha S-1500 finally crapped out on me (the second S-1500 to go bust in three years – I’m really not the biggest fan of Yammys right now!), so I picked up a Sony NS75H and an Oppo 970H and did an exhaustive comparison on my three-year old Hitachi CRT RPTV (51S700), connecting the players with both component cables and HDMI-DVI cables.

The short version of this post goes like this: both have great pictures once you have done a lot of calibrating. If you don’t care about having a universal player, go with the cheaper Sony. It features great usability and has a picture that is very competitive with the Oppo.

What I like about the Sony:
The response times seem a smidge quicker than the Oppo, and Sony’s interface is very intuitive and easy to use. I would say Sony had the edge here.

Sony’s remote, while hardly exciting, is well-laid out and ergonomic, as well as easy to use in the dark. Edge again goes to the Sony.

Sony has a memory function that remembers the last 40 DVDs played and will restart them at the point at which they were stopped. Very useful for me, but you can also turn this function off.

Front-panel LED easy-to-read and not obtrusive.

What I don’t like about the Sony:
Front-panel LED is blue – looks cheap.

Entire player looks cheaply made, though it does seem sturdy enough. Just doesn’t fit well with higher-end components.

What I like about the Oppo:
Universal player plays SACDs and DVD-As.

“Direct Play” feature can (sometimes) allow you to skip intros and get straight to the movie. This didn’t always work – you really have to time it right.

Amber LED looks a lot nicer than the cheaper looking blue, though sometimes the display itself is a bit harder to read than the Sony (less space devoted to text).

What I don’t like about the Oppo
Front-panel LED is BRIGHT! Wish there was a way to dim it.

The remote is poorly laid out, packed with buttons, and unintuitive. Very hard to operate in the dark, as the buttons are all the same size and spaced perfectly evenly. Really don’t like the remote…

Lack of any kind of "Resume Play" function after shutdown.

DVD tray looks a bit flimsy (I’m sure it’s not) and is a bit awkward to load and unload.

Like the Sony, the player looks cheaply made, though, again, it's sturdy enough.

Performance
Both players required quite a bit of calibration, but both had similar pictures once calibrated.

Both players passed blacker-than-black.

When using HDMI, both players had some issues with the color decoder, requiring me to crank up the green a lot on both players (up 15% on the Oppo), and the red a little on the Sony (up 3%). There was also a -.07 YC Delay error on both players at 1080i. Switching the Oppo to 480p corrected the error. Color accuracy was less of an issue when using a component connection.

Overscan was more of an issue on the Sony, with about a 5% loss all the way around (6% left, 4% top, 5% right, 5% bottom). Overscan with the Oppo ran 5% left, 1% top, 5% right, and 1% bottom.

Oppo seemed to handle the 3:2 pulldown a bit quicker than the Sony, and seemed to have an overall edge on deinterlacing as well. However, the Sony did a great job and Oppo’s lead was not significant in this area.

Surprisingly enough, the 1080i picture on both players was very soft, requiring me to increase the sharpness to at least 50% to get proper detail. The component picture also required sharpening, but not to the same extent as the upscaled picture. The picture got noisy very quickly, however, so it took a while to find the right balance between acheiving detail and being overwhelmed with noise.

I’m less skilled at determining audio superiority. Somehow I feel like the Sony got just a little more mileage out of a soundtrack, but they both sounded good.

Conclusion
I haven’t made my final decision, but I’m leaning towards the Oppo, despite its drawbacks. The picture seemed to be just a touch better than the Sony, and it’s easier to return the Sony than the Oppo. My Yammy still plays SACD and DVD-A (only the video chip is fried, apparently), so I *could* continue to use it for audio and the Sony for video, but it would be nice to have one player for everything.

So, for anyone looking at these two players, my recommendation would be to go with the Sony if you don’t need a universal player. The differences between the two in terms of PQ wouldn’t be enough for me to justify paying an extra $50, and the Sony seems to be the more user-friendly of the two.

Thanks for the great review! Did you compare layer change on the two players? I know that the Oppo is supposed to be undetectable. What did you notice on the Sony? If you could time it that would be greatly appreciated.

Hey! Thanks for reminding me about layer change. I haven't watched a full DVD on the Oppo yet, but I have watched a couple on the Sony. I remember seeing one layer change, but it was very fast (like a frame stutter). Blink of an eye. Don't know if I could measure it if I wanted to...

Tonight I'll fire up Gladiator and check out the layer change.

Checked the Oppo for layer change - either I can't remember where the layer changes are on my DVDs, or the change doesn't stop the Oppo at all! It's good when I can't figure out where the layer change is... :)

I just wanted to thank you for the great writeup! I was debating over which Oppo to get and then saw the NS71HP at Costco (which is, as far as I can tell, the same model as the Sony NS75H,) and couldn't resist.

What kind of calibration tools do you use?

Thanks!

I use Digital Video Essentials and the AVIA calibration disc. I also use a few discs that I've been using for years to test a system (Sleepy Hollow, Matrix Reloaded, Gladiator, Star Wars, and a few others). They are not all reference level DVDs, but sometimes, that's the point! ;-)

djironic,
Thanks for checking the layer change. Kris at Secrets should have his review of the Sony 75H up very soon and we will get a measurement there. I'm using an older Panny (not the Faroudja one) and the layer change is very noticeable so besides video performance the undetectable layer change is my Holy Grail! Oppo may be where I wind up as well.

The NS71HP, from what I'm told, is simply a Costco-exclusive version of the NS75H. Some minor cosmetic differences on the front panel, but the internals and rear panel are identical---and it includes an HDMI cable!

Guessing the cosmetic alterations (HMDI blue front panel LED seems to be smaller on the 71HP, for example) may have been done to lower the cost slightly.

One thing to keep in mind with these players is that Sony has incorporated a 'fix' to correct the vertical squeezing which occurs when the image is upscaled (a problem with the MediaTek chip). Oppo offers a beta version of this fix. However, in both cases with the players, the 'fix' causes severe horizontal resolution loss on resolution patterns which is why Oppo doesn't implement it.

The vertical squeezing is what accounts for no overscan on the top and bottom of the image for Oppo. If your display has overscan, you may not even notice this. However, there is a minor distortion in picture geometry.

Hmmm - so i either get a squeezed picture or I lose 8% vertical? I guess losing the vertical is preferable to squeezing, but neither sound like a good situation. :(

BTW, the 'fix' must be more than beta at this point since it arrived with my new Oppo. The firmware I'm running is the latest production firmware...
