I expect some UFX vs Apollo reviews and samples, maybe some of you own both.
Well, like I said, both units are very good, and as I noted in my post, on a standalone basis, not having the Apollo right next to it, I'd be pretty happy with the UCX. I wonder how much of the sound difference comes down to the preamps, and how much the converters. I.e. a standalone preamp into the UCX's converters might sound better. I don't have the time or inclination to do this kind of experiment, though. In any event, the Apollo is a good chunk of change more expensive than the RME; one would expect it to sound at least a little bit better.
Regarding drivers and buffers, I've uncovered two bits of information today.
First, turning off the Input Delay Compensation in the UA console gets my Apollo roundtrip latency down to 5.83 ms (3.44 in, 2.40 out) with a 32 sample buffer @48khz.
Next, I've found a bug (or maybe it only affects me) with RealVerb Pro -- if I change a preset, the console crashes. This is not a major annoyance; I suppose there will be several kinks to work out. Similarly, there are features I would like to see in future revisions of the UA console software, and I'd start with the opportunity to select pre- or post- sends for the auxes. I'd also like more auxes.
That's it for now, back to experimenting with this marvelous new box.
