Back to topic:
I listened to Stef's clips earlier today, before he pulled them. Some observations: If you want us to analyze amp/cab tone, then turn off the reverb, delay and effects. Play some chords. Nothing fancy, play an A. Play an E. Play a D. Play up the neck, just power chords. Do some single note stuff and let it ring. What you posted made it impossible, IMHO and respectfully stated, for me to judge any base tone differences at all. You didn't even play the same things in the two clips. The clips as posted were not done with respect to judging what you were asking us to judge. IMHO.
In Cliff's clips, the differences are essentially in the playing; the tone was pretty much the same. Anyone hearing a difference would be straining to do so IMHO. The only difference I heard at all was in the playing pretty much.
All IMHO, YMMV and not out to flame or injure anyone's e-cred. Just sharing my thoughts.
