Let the hive mind of Engadget get that for you.
"I finally got a new laptop with a lone USB 3.0 port. I'm now looking at getting a USB 3.0 hub with a power adapter so I can use both of my USB 3.0 hard drives at faster speeds. I've read lots of horror stories where some hubs either don't come with power adapters -- and as a consequence the portable drives don't work with them properly -- or they are designed poorly which results in USB 2.0 speeds. Or, the hard drives keep getting disconnected. Do your readers have any suggestions or experience using USB 3.0 hubs? Thanks!"
I don't understand something. Home theater speakers can produce frequencies up to 50khz but these high end amps and av receivers max out at 20khz. What gives.
The average human ear in its prime is only suppose to be able to hear up to 20khz, so what is the point to go above that?
I don't know if this is the answer or not, but maybe inherently, speaker design makes it easier to obtain the higher frequencies easier and more economically. Maybe with amplifies it takes a harder and takes more money to do it, so when you factor in the human ears limit, there really is no point dumping more work and money into going above what it can hear.
Careful not to confuse the rated bandwidth with the complete bandwidth, either. I doubt that Bryston has put a "brick wall" filter in at 20kHz, and the PR says the new models have improved response AT 20kHz, not TO 20kHz. That said, zargon is right -- very few people older than maybe 8 years old can hear above 20kHz anyways.
