James 寫:这次ＲＡＹＭＯＮＤ等弟兄来玩，真令人高兴。尽管三个系统都没有调试过，但是“丑媳妇也要见公婆”。目前影院系统碰到的问题是：
１）高音号角有“嘶”声。如果跳过ＥＱ８０２４，“嘶”声就消失。试着把ＥＱ的高频处衰减，不起作用。ＭＡＲＫ提议把ＥＱ的接地点悬浮处理，等有空试试看。
２）亮度不足，线条粗，看上去好象有层雾。最近去了上海９寸管发烧友ＴＯＮＹ家，震撼！决定采取下列措施：
Ａ）把幕布换成高能布。因此要把ＣＩＮＥ７拿下来，放在茶几上（要买个结实点的茶几），所有的线重新布局。
Ｂ）买一台ＤＥＮＯＮ３９１０，用它的数码输出。
Ｃ）买一台倍线器。最好是二手的ＦＡＲＯＵＤＪＡ。
３）自从上次ＡＬＡＮ ＬＥＥ来调试后，没有再调过ＣＩＮＥ７。要把说明书找出来，“黄酒吞服”后，细调一下。
采取上述的措施后，图象质量应该有所改善。不知大家有何建议？
谢谢。

I believe all of your proposed move will surely improve the picture quality from your projector. However, for my personal point of view, I think you should do it step-by-step and see the improvement by each addition of equipment.
(1) Fine tune the projector as at present the both side of the projected image are slightly curved not straight. Besides, its seems to be a little bit out focus. These two parameters are very easy to adjust by yourself.
(2) Use your new Denon 3910 Component out to see picture improvement.
(3) Buy a second hand Faroudja line doubler to enhance the resolutions.
(4) To take some samples of differenct screen materials to see any improvement in picture quality. You may not need to use high gain fabric. There may be no need to re-locate your projector from ceiling hanging to table as well as re-wiring tasks <--- big project.
I hope the above can give you some simulation or thoughts for possible enhancement with wasting a lot of efforts. I am looking forward to re-visit your great setup after you have fine tuned them.
我上次去落大魚!
