It also depends on the spectrum of the material you are listening to, and probably a whole 'nother handful of factors. For example, I have good hearing up to about 22KHz, and spotty up to about 24KHz (with a couple of spikes of tinnitus down below 8K :-)). For pop music, or music just kind of playing in my living room, I'm quite happy with my cheapo receiver that only goes up to about 15KHz. For classical stuff or uncompressed folk music, I like my nice Sony headphones that go up to at least 22KHz. The same is true for video. For watching CNN, or most network TV, an NTSC monitor works pretty nicely, even if I can see the interlace flicker, as long as the ambient lighting isn't flourescent. For movies, or for things like weather maps or financial charts, I'd love to be able to see them in HDTV. -- Amanda Walker InterCon Systems Corporation "Many of the truths we cling to depend greatly upon our own point of view." --Obi-Wan Kenobi in "Return of the Jedi"
