imo 320k mp3 is totaly worth it. hard-drives are DIRT cheap now, and the price is still dropping like flies. (u like that?)i think the average listener WILL know the difference in thier subconscious, even if they won't be able to figure out what it is. that can actually be worse than someone understanding what's going on and knowing why they are putting up with it, or why they are changing the channel.of more importance is the quality of the end-listener encoder you're using. i recommend using the latest Spacial Audio Encoders for Winamp (btw version 4 is coming out soon). it comes with the newest version i've seen of Fraunhofer's FAST codec, thier current reference coder... and it sounds great below 128k, even compared to the classic Fraunhofer DirectShow + Shoutcast 1.8.0 trick.at radioio i wish we could use AAC though. even a 320k AAC file will beat a LAME encoded mp3 hands down, and 500k AAC is nearly statistically impossable to ABX. but 320k LAME mp3, with good settings on the encoder, such as:-b 320 -q 0 --lowpass 22.05 --interch .001 --priorityusing LAME 3.97b2 you will get nearly cd-quality... i have trouble ABXing almost every test file i have with that setup, and i mostly listen/test/tweak/etc through Apogee DAs. 8)well i was going to type more, but freakn windows just crashed explorer.exe, and it won't come back... so it's reboot time.
