So would you say that in your specific case going from AN EI to AN HiB C core made a huge leap in transparency, soundstage, detail etc.? What about tonality did it lean out just slightly by going to the new transformer? I ask because one of my amps, the JJ 322, has JJs equivalent to a Super Hi B double C core (grain oriented Si steel with thin laminations of only 0.13 - 0.15 mm) that also weigh a quite a lot (probably at least 7kg) and it is probably one of the most tonally neutral 300B amps I have heard. Only a bit warm but with a lot of resolution and quite well resolved and powerful bass.
The other amp(s) (monos) with the more exotic metals but EI frame have a bit more tonal richness through the mids and bass is similar. Highs are similar. That might not be the trafo but I suspect it is. I had a look under the cover...it is fairly big but needs to be given the amount of current running through it (2 x 6C33C have about 500mA bias current on the plate at 210V).
BtW, have you heard the OTO SE signature, which I believe uses a similar HiB C core (pretty big one from the pictures)? I was thinking about that amp a bit as there is an AN dealer nearby where I live.
