Couple of things here
The ON/OFF contrast performance of the SONY SRX-R608 measures 10,000:1 peak and circa 8,000:1 when accurately calibrated. There is no scenario wherein it measures 15,000:1. And further to my measurements confirming as such, this information is from SONY themselves. Screen is irrelevant with respect to contrast within blacked out environments. Ambient light rejecting screens can help to reduce the negative impact on contrast performance due to environmental light, however no projection screen exists which is able to increase the dynamic range and hence the ON/OFF contrast performance. Negative gain screens will deepen the black floor however concomitantly will lessen the white level as well, akin to an ND Filter. Consequently, "15K:1 with iris and screen"
is incorrect misinformation.
The SONY SRX-R608 is essentially a stripped down, compacted, budget version of the SONY SRX-R815 with the target demographic being small cinemas where a lower price than the SONY SRX-R815 is desired and where retaining reference performance over the long-term is not a priority. Wherein, both the SONY SRX-R815 and SONY SRX-R608 have essentially the same identical luminance dynamic range and hence contrast performance. Both projectors are singular blue-laser through yellow phosphor panel SXRD LCoS and utlize color filters to achieve high coverage of DCI-P3 color gamut within BT.2020.
However, the SONY SRX-R608, being a stripped down, compacted, budget version of the SONY SRX-R815, does not have the tools that come with the SONY SRX-R815 that are used for optimizing and retaining the baseline image quality over time, which includes image uniformity as well as any drifting or degradation with respect to contrast performance. So in this regard you get what you pay for. Wherein, personally, I consider these features of the SONY SRX-R815 to be all-important, especially when the intended usage is home theater, and particularly high-end home theater, which is the application here.
The fact of the matter is that Barco's new Series 4 range of D-Cinema projectors, which are full RGB laser projectors with native 4K 3-Chip DLP TRP chipsets, and which are very similar cost to the SONY SRX-R608, significantly outperform it with respect to both "colorimetry and MTF"
. Where the SONY SRX-R608 achieves 100% coverage of DCI-P3 within BT.2020 the new Barcos achieve 99% coverage of BT.2020. Remember the SONY SRX-R608 is only singular blue laser; and there is quite simply no contest as compared with full true RGB laser as far as color performance is concerned. And with respect to sharpness and MTF it should be noted that we are comparing LCoS vs DLP, wherein the latter is superior with respect to not just sharpness and MTF but also image uniformity as well, as typically also RGB pixel alignment and chromatic aberration to boot.
So, no, the SONY SRX-R608 is not the best projected image at CinemaCon 2019 as far as "colorimetry and MTF"
It probably was/is as far as contrast and black level performance is concerned, however given the competition are touting the usual circa 2,000:1 - 5,000:1 ON/OFF contrast performance of almost all D-Cinema projectors this is not really cause for excitement. SONY's objective here was and is to simply have better contrast performance than the competition and in this regard 10,000:1 ON/OFF contrast achieves this. Is this the level of contrast performance that we desire or consider acceptable for high-end home theater, taking the performance of other high-end projectors into consideration, such as the JVC RS4500/Z1, JVC RS3000/NX9, SONY 995ES, SONY 885ES, and SIM2 HDR DUO PLUS? Nope. And not even close! It's even a step down as compared with the SONY 5000ES.
There are other projectors with superior colorimetry and MTF. There are other projectors with significantly superior contrast performance. And there are other new projectors in the pipeline as well which will outperform the SONY SRX-R608.
And for what it's worth, you can't really properly evaluate the performance of a projector at a trade show. You need to do so within a controlled environment; which is precisely what I have done. SONY Europe headquarters is located only 20 minutes away from my home and I have had numerous opportunities to spend entire days there comprehensively evaluating their D-Cinema projectors; as well as at Alan Gouger's; and in my A/V laboratory.
As per usual I am just being completely impartial, straight, and honest here… so sorry if I am being a party pooper!
This is most certainly is not the successor to the SONY 5000ES that people have been and are waiting for. Hopefully we will soon be seeing a new projector which qualifies as a proper upgrade from the SONY 5000ES. The SONY SRX-R608 is not that projector
