Sure, I am a total audio 'ho, and I'll take a musical fix when and where I find it. But I want to be sure no one thinks that I think this can really be done on the cheap. It would have been more honest (and more helpful) to say earlier that I am not sure exactly how much my brother spent on his A/V system, except it was between 50 and 100k (USD), for the A/V system, alone. In the meantime, I have tried various amounts of booze to go with the PBS/Ovation/TV operas on my own and others' "big screens" with nowhere near the hit I got from the grand, high $$$$$$ system. Maybe there is a "Bang-for the Buck" way to do this, but I believe there IS a sensory threshhold that must be crossed, here; and since we, as humans, are over 80% dependent on our eyes for information, I would not underrate the visual components, here.
FYI, my brother said his A/V contractors had done recent local "concert hall" and University Music Hall "Reinforcement" systems; and IMO, it sounded like it...
Yes, I am currently biased against hall "reinforcement" that I hear; but I have to say, his home opera sounded "authentic", in the "modern" sense, and the vivid imagery somehow combines to put it "over the top"; "better" than seats I can afford, anyway, not to mention the "captured" epic performances!
