All the *real* X-Fi cards can output without resampling, the ones I've tried worked well in foobar via asio (I haven't tried kernel streaming). eax5.0 in gaming mode was just an added bonus
I know there's alot of driver support grumbling about creative on the net, but I have had no problems with the X-Fi's in Vista x64. Can't say the same for the Chaintech AV-710
Under $100 new, that you can find online and in stores, I'd suggest the half-sized X-Fi XtremeGamer,
$50 after rebate at newegg. It's a squashed XtremeMusic sans gold plating and expansion options via I/O console or I/O drive. It does however have standard pinout for front audio ports on standard ATX cases.
If you're lucky, you can find the discontinued X-Fi Xtrememusic new online (here's
one for $50) otherwise ebay is your only source. Make sure you get model# SB0460, (SB0670 is an oem card that had functionality limited, and drivers direct from creative or from
retail cd's don't work for it). Has that funky 10-pin plug that only works with front audio on oem case by dell, gateway, etc. (There are a few individuals around the net who sell adapters to standard atx cases, myself included)
Either way, If you're going to use analog outputs, I'd recommend
hotrodding your X-Fi at least with a replacement op-amp on the front L/R. If you're not into soldering, check the thread, there was someone offering to mod cards for others.
(Don't bother with an X-Fi XtremeAudio, it's really an Audigy SE so good luck getting playback without crummy creative resampling.)
I bought the Elite Pro once with rebate, sold the I/O console (same thing as optional I/O console upgrade kit creative sells, I didn't need it, plus the opamps and dacs in it are inferior to the ones onboard the elite), and ended up with my money back after 2 months
which worked out well with 3 month billmelater
Anyway, except for the Elite Pro, all the full-sized X-Fi cards are the same, differences being whether it has 2 or 64mb of memory, whether it has a glowing logo block (and color), and what extras are packaged in the retail box. The Elite Pro has 64mb of onboard memory of course (and blue led lit logo), but it also has an improved pcb layout, upgraded dacs and op-amps, and better and larger capacitors. It has 116db SNR as opposed to 109db SNR the other X-Fi's have.
I haven't seen any reasonable benefit with additional onboard memory (pssha, *xram*), save in battlefield 1942 -_-
