RESULTS
I settled on the 1st one below. With the runner ups as follows:
WMP9 WMA-9 VBR 50-95 KBPS CD 32Meg 16Min
WMP9 WMA-9 VBR 85-145 KBPS CD 54 Meg 16Min
MJ MP3 VBR Normal CD 56 Meg 20Min
MJ MP3 CBR 160 KBPS CD 69 Meg 14Min
For dependable down and dirty speed with MP3 CBR 160, MJ won out on test accross three CDs and three different CDS. On one test it beat MM and WMP by a minute and a half. This was my favorite format.
For now though seeing as how my portable Riovolt being a huge proportion of my listening use, I am going for the tight WMPer WMA Ver 9 VBR 50-95 kbps. Sound and speed both came into play. The quality was very good without all the high pitched noise from the higher VBR recordings. And for speed in a VBR it beat the MJ MP3 VBR by 30 percent. And of course at less than half the size of my old favorite it was a no brainer.
As for my testing limits I was limited to WMA and MP3 and CDA for my portable. I did lots of other sampling that I wont bore you with as they were easily illiminated. I listened with three sets of headphones as well as home speakers.
I am hopefull Media Jukebox will support WMA-9 VBR soon so I can go back to ripping CDs with it. But no matter how you cut it, I will still be using my registered MJ for most of my needs as it is the most powerful, depenable, and flexible of the better jukeboxes out there.
