Ian,

Kudos to all of you at Axiom. All specs are impressive so far but I am particularly impressed with the noise floor and the frequency response. It looks like the 3dB point is out in the boonies at around 50KHz. When available, can you post the graphs for 2, 8 and 16 Ohms so that we can see how well the feedback network is designed ? Let us also marvel at the phase response.

And you've managed a really short dead time (maybe 10 nsec or less) with virtually seamless switching to achieve such excellent THD.

I bet there will be a big party at Axiom when you've finally finished this project.
