ok.. so what kind of signal path would i need to achieve to TRULY take advantage of recording at 192k?

also.. considering that eventually my cd will need 2 b converted to 44.1k, should i really record at a multiple of 44.1k? (ie 88.2)

i do want my mixes to b ready for surround mixing, etc

any insight would b helpful

To be serious, the studio arrangements needed to be able to hear the differences at high frequencies are not worth it for most. Now… first, work in 24 bits, second if it's going to end at 44.1, 88.2 will do, but it'll be most important in transient heavy signals. Personnaly I'd say, it'll most effective for acoustic instruments, voice, symphonic orchestra and the like, maybe some really fine tuned (real) analogue synth patches… else, it's a waste of CPU and drive estate.

Also, you should try the record the signal at both frequencies and compare if it's worth it. it's not because your interface can go up to whatever KHz that it'll be at its best there… things like the clock quality in the A/D converters do make a difference.
