Sorry, have not posted since original post. I've been out of town on business, finally back!
Unfortunately, after watching a few Dolby Vision titles (specifically Spider-man Homecoming, but others as well) I've noticed a very obvious lip sync issue. The actors lips on the screen are moving about a second after the audio plays. I should stress this only happens on DV titles, I have not run into this issue with HDR or 1080p Blu-rays.
There is a new firmware that came out while I was out of town, and after downloading it just now I will watch the same DV movies again this week and see if anything has changed. *crossing my fingers*
As far as overall impressions, I LOVE the build quality on this. Its built like a tank. The loading is whisper quiet, and feels high quality. It loads movies slightly faster than my previous OPPO 203 and my current Panasonic UB900. I wish I still had my OPPO 203 to do a true A-B comparison, but alas I returned it back to OPPO.
As for picture quality, it looks great. Very natural colors. Although I feel the OPPO 203 seemed sharper? Cant tell if its some sharpening filter action going on with the OPPO but anyway, it seems more natural on the Cambridge. The colors however look better on the Panasonic UB900, no doubt. If Panasonic ever came out with a 4K Dolby Vision player and kept everything from the UB900 internal processing the same, that would be my next and probably final 4K player purchase.
As for the audio quality (using HDMI out) the SACD titles I've played sounded very good. FYI my current receiver is a Pioneer Elite SC-LX502 which uses an AK4458 768 kHz/32-bit DAC (there is no DAC in the Cambridge itself). I'm using a very affordable set of Pioneer Elite ATMOS 5.1.2 speakers (designed by Andrew Jones, formerly designed the TAD $80,000 Reference One speakers), take it for what its worth. But it makes me happy to hear SACD and regular CDs sounding about as good as I can expect from my modest Pio speaker setup. Color me impressed.
I'll post more impressions as time passes on. But for now, I'm keeping the CXUHD. It does all I need, (Dolby Vision, impressive SACD playback, and built like a tank). The Cambridge name/reputation doesn't hurt either. This is one player I feel will last me awhile. And I'm also keeping it because there is nothing currently out there that is perfect. The OPPO has its chroma issue, the Panny doesn't play DV, and the LG (while able to play DV) is too cheaply made in my opinion. I want something that will last awhile, and not give me disc transport issues after 3-4 years. So until Panasonic makes a 4K Dolby Vision player and has a Chroma processor like the UB900, I will stay with the CXUHD.
