Well guys... I have good news & bad news.
I managed to fix the issue with my HD70 on my own, which means that I probably wont be sending it to Optoma for repairs. This means I can immediately ship out the Acer to Art by mid next week. As a result, we will get our review of the Acer unit much sooner than expected.
After re-attaching my HD70, I have to be honest and say that the color reproduction of the HD70 is much better. Hopefully, Art will be able to calibrate the Ace to look alot more natural. It's almost too sharp on many tests I've ran.
At this point however, to my semi-trained eye, the HD70 is a better projector for video color reproduction. The Ace can probably be calibrated to display just as well but we'll have to wait on a more experienced calibrator for that.
I can tell you, if comparing the HD70 to the Ace "out of the box" with only Color, Tint, White & Black adjusted... the HD70 is the clear winner. Beats the Ace on black level also.
P.S. I apologize for my posts, as they may seem to be random but I am giving it to you as I experience it. Plus, so far I may be the only guy here with both the HD70 and Ace in his immediate possession and at this price point, these 2 units are head to head. Anyone who is considering buying the Ace, is more than likely a candidate for the HD70 and vice versa.
