So, I would like to have mp3 files close to 192 kbps. I listen mostly metal (various types - heavy, power, black, ...) and --alt-preset standard seems to create mostly bitrates of 200-250 (tested with several albums). I consider this to be too high, how should I create the files to get lower rates? Should I use ABR with --alt-preset [rate] or maybe some VBR command line (for example, edited -r3mix), using -V[n] to adjust the bitrates? Any suggestions?

Considering that MP3s primary function is to reduce bitrate while maintaining a fairly high degree of quality (but not audiophile/archival), it is understandable why the creators of the spec choose 16KHz as a cut-off. I've encountered a variety of musical tracks where I could not ABX a file with a 16KHz cutoff and a full-bandwidth one. I'm not saying this occurs in the majority of files, but this phenomenon does exist. This is because many CD tracks don't even store sonic data up to 22.05KHz...some experience significant roll-off above 18KHz or even less.
