I've had no trouble playing 192kpbs streams using stock AMPlifier and AHI 4.0 on an A4K with CSII 060. No slowdowns in PIO or DMA modes on the Deneb. Given that PIO worked, I see no reason that rapidroad would not play smoothly when the updated usbaudio class comes out, at least if connected to an Xsurf100 card.
I suspect games that use AHI might cause hiccups, but I never tried. I may get one for MP3 playback alone. Deneb is a fragile device and should probably not be used as anything but a DMA HDD controller.
