Thanks Caleb. The Radial looks a bit more robust, but costs about 3 times as much as the Peavey. I know it doesn't have the inputs or digital outs the poster CJ was looking for, but I haven't seen something like that without proprietary drivers.
The one potential advantage of the Radial is that the Peavey is 48 kHz max and the Radial would let us play back raw 24/96 ProTools files. I am not saying 24/96 recordings sound noticeably better than 16/44 in a live setting, but for using original recordings as backing tracks in live performances, sometimes we want to mute the tracks of the 1, 2 or 3 performers who will be performing that night. Obviously, in the studio we could do several mixdowns with different performers muted on each, but sometimes we are in a rush and just want to bring a copy of the latest multitrack mix and mute the tracks we need to mute. We have done that a few times and used the headphone out but it would be nice to have the flexibility to use the USB digital out and get a little better sound.
Scott, how do you like the Radial USB Pro you just got?
