I'm still using the Bravo, but now it's with the Bel Canto DAC2 and it sounds great with the XCANS amp into a D7000. That's a keeper of a setup.
But the main reason I posted was because I think I finally figured out why the Bravo isn't one of the components that supposedly improves with the optional Supplier PSU, according to Firestone. I have been participating in the iPad DAC thread, and basically some USB DACs work without a powered hub, and some draw too much power from the iPad and shuts down the digital audio output from it. The Bravo is of the latter category, meaning it needs a powered hub in between the Apple iPad Camera Connection Kit's USB output and the Bravo.
This makes me think that there is no interaction between the incoming AC power required to operate the Bravo and the USB receiver component of it, and that the USB receiver is entirely bus powered so the AC power is going toward reclocking or something. So the Supplier's "better" power would therefore have no impact on the sound quality?
Anyways I finally found the original AC adapter, I've been wanting to get the Supplier out of this new setup for a while now for aesthetic reasons. So I will test this theory and see if I notice anything different in the sound.
