Designed without DACs for improved noise and picture quality! Noise? Really? I think they have to mean it's quieter than the Oppo surely? It would actually be a noisy picture because all 4k pictures are the same, right?
WHF reviews suggest not all 4K players are equal in picture quality.
If you check AV forums reviews (those reviewers are professional TV calibrators too), you'll find this in every single review:
"As long as the player isn't doing anything it shouldn't be, the 4K images produced over HDMI will be identical from one player to another."
Back in the days of DVD and composite, S-Video and component analogue video outs to an CRT display, there used to be quite a noticeable difference between a budget and an expensive DVD player - one assumes component quality, ability of the drive to pick up all the information from the disc with minimal error correction, and the digital to analogue circuitry with regards the video side of things would all be superior on the higher priced machine.
Of course with HDMI, it's all digital from disc to what is effectively a digital display with LCD panels, so in theory there shouldn't be any diffence in picture quality.
However, the same could be said of CD transports using SPDIF or Toslink to a digital amplifier; it's essentially a digital signal from disc to a digital amp, and so all transports should sound the same.
I did an matched level AB comparison between my 3 CD/DVD/SACD Sony players using SPDIF out into my Sony TA-DA9000ES digital amp, and to all intents and purpose on unfamiliar music, they sounded the same, despite a difference in cost from the cheapest to the most expensive of circa $2,500. And yet,,,, on disks and music that one knew really well, there was a refinement, subtltie and nuance to the sound that the cheaper player could not manage; broad strokes yes, but nuance and differences in tonal timbre, smoothness, detail resolution all favoured the more expensive players. A close thing, but the difference was there on critical listening to well known recordings.
Having said that, in a blind AB on unfamiliar music, I doubt one would easily pick the difference...
Similarly I think with digital video, I would hesitate to say that picture quality across different players will be absolutely identical, but rather more alike than dissimilar.
Probably diffcult to spot any real difference on unfamiliar films, but I would think the advantages of better quality transports, less error correction, compoent quality, circuitry design would all make small but subtle differences one might only notice on very well known films, and even then probably only noticeable in certain scenes - but it is likely to be there no matter how hard it is to easily detect visually.
Certainly if you want to run a calibration test disc and calibrate the player/and or display, the cheaper players offer at most one or two picture modes; if you want tight control over picture parameters for calibration purposes, then the likes of the Oppos and Cambridge players will offer a lot more control of picture parameters that can be adjusted to ensure accurate calibration.
That plus the noticeably better mechanical construction re casework etc, and a nicer remote, attention to sound as well as picture quality, would make a ES Sony, Oppo, Cambridge, or other 'high end' Bluray player an attractive prospect re ownership despite the higher price than more budget orientated offerings.
Generally, but not always, one gets what one pays for...
