The new S7 has the new C-core transformers which alter the sound a little bit. If you have other EC amps and are used to the EC sound, certain recognizable traits will no longer be there since the output transformers have a very large affect on the amp's sound - even more than tubes. (This is why I also recommend rolling transformers, because it's even more fun.)
The C-cores are less organic sounding. The older EI cores were slightly thicker in the bass and had a little treble bite (I am not implying a negative thing here.) The C-cores have a more neutral textured bass and better detail extraction overall. The highs are brighter, but also smoother. Overall, I feel the new C-cores get out of the way better than the EI-core. I had no issues with it sounding slightly brighter since the presentation was smoother. In any event, the brightness can be tamed with proper tube selection.

I am very interested in this electra amplifier and would also like to know any difference between
the super7 mkI and mkII. Please do share your impressions.
