Default driving AlephX unbalanced reasonable?

Hi!

I saw that the AlephX can be driven with unbalanced inputs, however I think this will greatly reduce the effectiveness of the supersymmetrical design, no?

Like in the X-amps that have no unbalanced inputs at all.

Thanks for any insight! Cheers, Hannes

The PL products have balanced and unbalanced inputs and there
is almost no difference in performance. If you ground the - input,
then it amplifies the difference between ground and the +
input.

With a single-ended input you don't get the noise cancellation
from balanced lines, but that is an artifact external to the
amplifier.
