If this is done well this will be really interesting...
afaik the VHP series as a whole has no opamps, the VHP-1 doesn't, and the VHP-2 is an extension of that
as far as an upgrade from the Prelude, remember, it'll only be in sound quality, not in performance, as its still based on the 8788 (an amazing piece of kit, as far as music/movie quality goes), but it'll slug down for gaming and other things which the X-Fi processor will scream through
now, that shouldn't stop anyone from this card though, lol
and if that wasn't enough, they have the XT option board, which brings 5.1 to analog RCA line outs (noice!), no idea how much more that'll cost (guessing over $200 from the look of it)
per their specs, its a JRC 4580 for all channels of analog out (looks very nice)
and TPA6120A2 for the headphone stage
and here's the TI IC:http://focus.ti.com/docs/prod/folder...tpa6120a2.html
which looks superb
as far as the op-amp/no-opamp thing, CI claims the VHP series have no opamps, but instead use current feedback, which is what TI is claiming for the operation of the TPA6120A2, so I'm guessing there is some discrepancy in what CI is really claiming
I'd love to hear this card side-by-side with my CIA setup, but idk if I'm willing to buy a third
