The Liberty B2B-1 can do both, for balanced you'd need two of them for a truly differential amplifier, IMO Vastly superior performance to running them Single ended, if the rest of your system is balanced.
And yes I do make them, there reviews here on AG and on Stereophile and Positive feedback too.
Good Listening
