"Turning to the measurements of the - we see a different intermodulation plot. This design is fully balanced so we should expect to see predominantly odd-order harmonics."
That's been egging at me. Is it true that fully balanced design gives predominantly odd-order harmonics?
If so wouldn't they have a natural sonic disadvantage as apparently we love 2nd and even order harmonics.
I've enjoyed some [fully] tube balanced pres that sound great.

Even-order harmonics are generated in each half of a balanced circuit but they have the same phase so when viewed differentially they cancel. The odd-order harmonics are out of phase (along with the fundamental) between the circuit halves and are seen as the signal.

Yuck ... you'd think someone would come up with a clever phase inversion that reverses the effect (for balanced circuit). But then if it were fleetingly small it might not make any difference, other thing unquantifiable and apparently unfathomable to the current set of measurement monkeys and we are were we are ... trust your ears. ;)

bjh,
there is whole gamut of gear out there using a wide range of technologies and topologies. It all appeals to someone so just pick what you like best and don't worry about how it works.

Right on!

Well, I haven't heard any sonic advantage from balanced circuits...or push pull ones for that matter. For coherence nothing beats top notch single ended circuits...whether tube, transistor or hybrid
