Just curious... do the F700, F900 and F90 all use the same internal processor (or CPU or whatever crunches the code)? I see no mention of the type of processor in any of the specs.

Well my guess is that the CPU's are the same, but they are different hardware.

For instance the 700bt doesn't have MSN Direct, this needs a chip to enable this option, so my guess is that it physically missing.

Also the 90bt has a better amp than the rest, so should in theory have better sound.

Has anyone been able to confirm this? Or should I ask what does Pioneer say makes it better?

Also I had a question regarding the differences between the three units.

The upgrades to the 900 from the 700 are MSN Direct and DVD? As far as the processor and rest of the unit they are identical?

The upgrade to the 90 from the 900 is a better amp? Anything else?

90, being a Premier unit also gets longer warrantly...

Now that I review the spces, the 90 also has 4 volt pre outs vs. 2.2 on the other two.
