Iceboy, I don't see a problem at all with using -b 320 in LAME if it's for your own personal use, is never going over a network, and you don't care about the extra space it takes up. All of which you've stated. LAME's VBR is meant to be as efficient as possible in the way it provides high quality at compressed file sizes.
Although, to be honest, your argument of "I dont believe in giving every frame anything less than the maximum for the best sound reproduction" could very well be used to justify keeping uncompressed WAVs around (or encoding into the lossless FLAC format). After all, MP3 is lossy. Don't you want the maximum quality for every moment of your audio? And there's certainly nothing more maximum than the exact original file! (Or one that outputs to exactly the same, in the case of FLAC.)
The point is that MP3, at any bitrate, is meant to reduce the size of audio files. The goal of high quality VBR modes, notably the old --alt-preset standard and newer -V 2 --vbr-new, is to use just enough bits to attain audio that is audibly no different from the original. Admittedly, this is only a goal, and the implementation is based on the very complex human hearing model and can never be quite perfect. However, with that disclaimer out of the way, a huge majority of folks will never hear any difference between such VBR modes and 320Kbps CBR. Many people actually have a very difficult time hearing any difference between files just over 128Kbps and the original audio, when challenged to a scientific double-blind listening test. Seeing the 320, much larger than 128 or 160 or 192, has a strong psychological effect that can cause you to think it sounds better when that is not actually the case.
But, as I said, it's your choice to make. Encoding in 320Kbps isn't a sin, maybe just a bit wasteful, but that's all.
