At 27 inches long, 77 pounds, and $7895 list, the SVP 420HB from SIM2 Multimedia is the least expensive, smallest, lightest CRT projector I've ever had in my home—although it's not exactly what I'd call portable. (Normally, my personal schlep limit is 55 pounds. One martini takes it to 65, but 77 pounds would mean a week in bed.)
It's an article of faith among audiophiles that you can "hear" materials. It just stands to reason that, if a loudspeaker cone has a certain sound when tapped with a fingernail, then everything it reproduces will be colored by that sound. This is why an audiophile will tap the exposed cones of an unfamiliar loudspeaker to see what they sound like. But not every material has a characteristic sound; some aren't stiff enough to vibrate. A wet dishrag, for example, has no sonic "signature." Only if you hit something with it does it make any sound at all, and then it just goes splat. But any material stiff enough to push air without wilting is likely to have some kind of resonant mode that we can hear, so you just know that a metal loudspeaker diaphragm is going to sound metallic.
Something that never fails to irritate me is an intemperately enthusiastic review of an outrageously expensive product. I'm sure this is partly because I hate reading about something that might just be every bit as good as the reviewer says it is when I can't afford to buy it. But I think the greater part of my pique is because I suspect the reviewer was so awestruck by the product's princely price that he couldn't bring himself to find fault with it. Oh, sure, he'll pick a few nits just to show how perceptive he is, but his "report" will essentially be an exercise in idolatry, with nary a question about value for money.
