Not an intentional bump, but gotsta say...
Now that the 20thA 4x12 loaded with V30's has completely smoothed out with its break in period, this thing sounds 
out-f*ckin-rageous.
My love for this amp will 
never die...  Imagine, it started perfect.  Now, after several months, the cab when cranked and mic'd compared to what I was recording a few months ago??  Noticeably different - and I loved it as it was!!!  But it just so happens, ya, it's done now - completely preened and pounded (with love).  Sounds just bloody unbelievable, I didn't think it could get better - it did.
I've heard some rumors that KT77's (specifically Genalex/Gold Lion) are the bees knees in this head (the EL34 loaded version).  I can't imagine it getting better.  If and when my tubes go or blow, I may try them out, but I'll make sure to order another quad of EL34's as well - this thing is just perfect to my ears.
THANK YOU REINHOLD!!!! 
 
The official end of my review.
