Balanced Signal Path Question

So I have a condition where I have a single ended source output feeding into a passive TVC volume control which then outputs via a balanced signal to my power amp. 

My DAC is a Metrum Amethyst, passive is a promithius standard TVC, and my power amp is a red dragon s500.

The root of my question is whether a passive TVC that is truly balanced can convert a single ended signal to a balanced signal. Both my amp and passive are true balanced conponents and I would like to have the benefits of that, possible running a long interconnect between my passive and power amp.
