You may get some moire problems with the PLV-60, it uses the same LCD chips as the 10HT which has been known to have a nasty interaction with microperfs in certain setups. I would recommend checking with a sample if you decide on the PLV-60. If you want the 200DM instead you should also seriously consider the Plus Piano at $3k USD, it uses the same chip and to my eyes looked very good (it also has a six-segment colour wheel). At that price you could get two and still save money! http://www.avsforum.com/ubb/biggrin.gif
I didn't know you could get Microperfs without the THX certification! After all the screen was developed in cooperation with THX.
In this case the equalizer is performing a different function than in most cases. It is not trying to correct deficiencies in room response, it is only canceling the attenuation introduced by the microperf screen. I believe that your statement relates more to correcting the effects of standing waves using equalization. In this case, it is difficult to get correct equalization for more than one location because the peaks and troughs of the standing waves are naturally very localized. However the equalizer included with the screen only corrects for the high frequency roll off when the sound passes through the screen, there should be no change as one moves off-axis. Besides, the high frequencies handled by the EQ are not affected by room acoustics because their wavelengths are too small.
Not being an expert in acoutics, perhaps this question is better referred to Russ in the Special Guests forum.
