Pricewise, the X9 is a bit more expensive (similar to the HD65 I think) but reviews (some, anyway) seem to say it's got better graduation etc than the 700x. Replacement bulbs seem to be a similar price - around £100 so really, it is going to come down to informed opinion by current users I think. Maybe the distance you'll be sitting from it / image size may be relevant too?
For example, I can't sit more than 8 feet form the projected image, although the projector could be mounted up to 10ft from a screen. This would give me up to an 84" diagonal to work with. Whether one of these PJs would give a better focussed image at this seating range I don't know.
Expert advice and opinions needed here (by two of us it seems)
Edit - The X9 is a bit brighter apparently too. There's a distace calculator on the InFocus site InFocus Distance Calc which seems to work OK if you remember to select the model in the top box first (I didn't at first)
i did find a small review by projectorpoint.co.uk:-
"Having done a side by side comparison of the Infocus X9 and its direct competitor the Optoma HD700X (using the high def version of Casino Royale) as our test dvd we noticed the following between the two models :
The X9 is the brighter of the 2 models on paper at 1800 lumens (the HD700X is 1300). In eco mode brightness wise the X9 is on a par with the HD700X but take it out of eco mode and the 500 extra lumens is indeed noticeable.
Like the Optoma HD700X, the zoom range is very limited producing very little flexibilty in where you site the projector. To make a noticeable increase or decrease in image size, like the Optoma requires you to physically move the unit backwards or forwards. However at this price point this for us is acceptable.
Colours & noise
Both units provide natural looking flesh tones but where the InFocus X9 truly excels and has the HD700X well and truly beaten is on the colour graduation. This was visably noticeable in the opening crane scenes on Casino Royale. The HD700X produced a lot of yellow banding around the sun whilst the X9 was faultless. On the same image, noise levels were mid range on the HD700X but again faultless on the X9.
The X9 has a 2 year warranty whilst the HD700X has only a year.
So which is better the InFocus X9 or the Optoma HD700X?
As with all projectors image quality is subjective. For us both projectors are a fantastic entry level projector in the world of high definition and we would be more than happy with either model. However if we must choose we would say that for us it would be the X9 for its outstanding colour graduation and the ability to produce images with colours from light to dark and everything inbetween with faultless detail."
Cheers Gary. I read the same review. But call me an old cynic, but I always have a mistrust of reviews - you never know who's on commission (and I'm not implying anyone is). Someone who's seen these two PJs would help a great deal.
For the price of a x9 you could probably pick up the hd65 but which is better?I reckon you would need to view the hd700x hd65 and x9 in a showroom with the same video source to make a good comparison,its been said theres nothing between the hd65 and 700 so surely the 700 is the winner here on price and value.
