Congratulations on acquiring the MA-2 amps! Hope you enjoy them as much as we have here; I cannot imagine ever going back to a tranformer coupled amp after living with these beautiful OTLs.
I drive mine with an Aesthetix Io Signature (with volume controls) using the single-ended RCA outputs (gasp) to great effect. I have yet to try them with a balanced cable so I don't know if that would improve the results I'm getting, the single-ended sounds so doggone good.
One thing that has made a very handsome improvement, however, has been the change to Sylvania 6SN7-GTAs for the input stage. This seems to be a very nice combination with these amps.
