Hi
I have used an Audio Precision to test these results and for one the output compensation is not sufficient to tame the HF peak when fed a decent length of cable (different values needed) and
the 100uF caps result in a 2dB rise at 10Hz. Take out one cap and the rise is about 1dB and take out both and it is 'flat' (actually about 0.2dB fall which is correct for this transformer).
The caps ARE in series because your schematic shows the physical 'centre tap' not being used so the current HAS to flow through both and not into a 'mystical' null point half way along the windings.
