Let the hive mind of Engadget get that for you.
"As someone who doesn't reside in the USA, I was wondering what would be the best way to get internet for my computer in the US for a couple of weeks? If it were Europe I know I'd look for some prepaid data. Is there anything similar offered by American carriers? A MiFi or a data SIM that I can tether from would work, but I'm trying to maintain a tight budget. Help!"
I'd disagree with you, impakt, but to tell you the truth...I have a 32" TV (big enough for MY living room) and I'd be willing to bet that if I got the SD DVD of 300, I wouldn't be able to tell the difference unless I was paying attention.
As far as SACD and DVD-A, I can't say anything about SACD since I don't have any discs, but the one and only DVD-A disc I have, really, is the Metallica black album (yeah, I know.) The only real difference I could tell is that the DVD-A disc was mixed for surround sound...other than that, nothing much. My ears don't go to the tippy top of the human hearing spectrum anyway, and never have.
With antialiasing, CDs can sound darn good. Without, they tend to have quantization errors. But hey, if antialiasing lessens the impact of quant errors, then is a higher-def audio format even necessary, especially given that 95% of humanity can't tell the difference between a regular CD and a good MP3--and that "audiophiles" think that vinyl records and tube amps sound BETTER? Um, okay, enjoy your "warmer" sound if it floats your boat. The other name for "warmer" is "coloration."
