C22 fully balanced?

Does anyone know if the new McIntosh C22 reissue (couple years old now) operates fully balanced? I know it has balanced inputs & outputs...but my understanding is that that alone does not necessarily mean the circuitry is wired to make the most out of it. 
I don't believe the C22 is fully balanced. The C1100 is. I do like the retro style of the C22. It looks good with MC75 or MC275 amps.
And the Audio Research LS28?

The only entry level fully balanced preamp I've come across so far is the Allnic L1500.
