Dynamic range is important too. As a rule of thumb you get 6 dB of dynamic range per bit of sampling rate.
96 dB between the loudest and the quietest sound? That may not be good enough for some classical music and the dynamic range of human hearing is much greater than that.
The one that he pointed out just happend to be a USB DAC used for PC. But they do come in other variant
You're still reading a CD which is just as prone to error as playing it on a CD player, no? Wouldn't it have the same error correction going on?
He means that the first time you are ripping it it can still have errors ... if errors getting past CIRC are a problem (which they aren't, since they generally don't, but I'll play along for the moment) they are just as much a problem while ripping.
This is a key point.I admit unless I'm using some high end headphones I would have trouble noticing the difference between a 320kbps MP3 and a lossless recording with most source material. But as Blazkowicz pointed out, certain types of music lend themselves better to compression than others; throw in a complex album where I know every little nuance and detail, say Yankee Hotel Foxtrot by Wilco, and I'll spot the difference pretty quickly. Womanizer by Britney Spears... not so much
