The Calrec UA-8000 "Polar"
And yes, it is transformer balanced all over; inputs, outputs, hell even insert points and tb mic inputs. All Lundall transformers.
Completely transparant sound.
Only bad thing is that the channel compressors are a bit too subtle for use as an effect. Not that they dont compress, you just dont hear them as much as you sometimes may want (like the SSL's). I was told the comp's vere co-designed with Mr. Mases of Maselec.
I have a complete DIY project of the UA8000's EQ module - PQ1549 - on my page, for those that want to have a shot on a project like that:
