On the subject of the Savage, I liked it a lot when I first got it.
Then I got the right speakers/cab & loved it (well, not necessarily the absolute best speakers as I've not tried many, but my hunch that the CL80 & K100 combination would be streets ahead of V30s proved to be correct).
Then I swapped the preamp valves & my jaw hits the floor every time I play through it (I did the opposite of what you did & put the JAN 5751 in V1)
OK, I won't pretend to be impartial on this :), but I do think that in terms of tone, gain, intensity & power that it's much better than the PB.
I know what you mean about the Savage's high-mid crunch. It's certainly not "scooped", but for me that's why I like it so much - the sound has so much "body", you just need to match up the correct speakers so it doesn't get offensively nasal. Also, the BBE into the FX loop is a big part of my sound, just makes everything clearer.
Interestingly, I've not got around to trying the E570 into the Savage's power section & brutal cab, but the E570s high gain is kinda half way between the Savage & how I remember the powerball. As I commented on my NAD thread, the mids seem "spongier" & less "stiff" than the Savage. The SE through the MJW pwer amp certainly isn't as shrill into V30s as the Savage was.
