Yes, that's correct. One aspect of the allure of parafeed'ing a pushpull output is zero, rather than very little, DC unbalance across the transformer. Mike posted his thoughts here. I've since measured both channels, and the worst of the two had DC-unbalance of <1mA, so not much here of concern.

That said, I've since put both DC-blocking caps back in, with the center-tap still lifted from ground, and it still sounds awfully good. It would seem a lot of the difference I heard is attributable to whether or not the center tap of the output transformer's primary is grounded.

Regards,
John
