When I went to see the JVC N5 last month, one of the other guys there for the demo had an LS10000 but hadn't yet installed it as his room wasn't finished or ready for it. With the new 4K JVCs being announced, he decided he wanted one so that was his reason for being at the demo, and had already agreed with the dealer doing the demos to trade in his LS for the N5 even though he hadn't yet even got the LS out of its box. He was there with a close friend who also has a home cinema and currently runs an Epson 9300. The guy with the boxed LS had an X30.
We directly compared the new entry level 4K Sony and a 9300 with the N5 in split screen. All were calibrated to D65 so they looked pretty much identical for greyscale and gamut. Quite often it's difficult to tell them apart when they're like that in a lot of scenes, so it always makes for an interesting demo there.
The guys seemed enthusiastic about the N5 and we were all chatting about various things. They knew me from a UK forum and knew I had an LS, and later asked if they could see my set up after we'd finished the N5 demo - that was a bit of surprises but I agreed so it was all back to my place after the N5 demo. I showed them various things on both BD and UHD and they seemed to enjoy it, especially full fade the black - that seems to get a lot of reaction from people who have never had that experience before.
Anyway, I've just found out the guy has cancelled his N5 and is keeping his LS which has now been installed and calibrated by the guy who runs the demos. Amongst other things it seems he felt the "LS trumped the N5 for clarity and detail" and "The demo at yours which put a few things in perspective, spending x more amount doesn't necessarily equate to a perceivable difference!! ". Those are quotes from the guy's PM so are his opinions not mine. He has a Panasonic 820 and a HDFury Vertex so can make use of WCG and HDR.
I didn't say anything at the time of the N5 demo, but I didn't think the N5 was that impressive or did anything better than the LS except for the tone mapping (and lacks FFTB), but with the likes of the 820/420 that seems to have equalled things out a bit there. I had also checked out a scene which seemed to have a some film grain going on with the N5 but not on the LS, even at full laser, so it seems the JVCs still add image noise to everything, but I need to double check that to be sure, though I'm 90% sure that's the case. I think Ekki had seen it on a paused grey field when he did some preliminary testing with a new 4K JVC so I think that confirms it.
I've had a few people round for demos at my place because it's not easy for people to see the LSs at dealers, so I get the occasional message asking if a demo is possible, and it's not unusual for them to buy an LS on the back of it. The Epson laser must be doing something right then.
I really hope Epson have a 4K laser in the works and haven't dropped it entirely as so far I think that might be the only thing that will entice me to upgrdae, as nothing else I've seen so far has done that.
