Mixed signals about my mixed bits

    My signal wants to go out of my 'puter , to outboard effects, then back to 'puter.
    I have limited in/outs left on my soundcard (until I upgrade). I now have:

    1 @ spdif I/O (or aes/ebu)
    1 @ toslink I/O (this actually acts as a split off the spdif)
    2 stereo analog inputs (4ch)

    I also have 2 outboard effects I want to use that need routing:

    1 @ Lexicon PCM80 (18bit)
    1 @ Valley 730 dynamap compressor(20bit)

    I'm thinking about two ways to do this:

    One is way is use Toslink I/O with the compressor and use the Spdif I/O with the reverb. They will share the same split signal.

    Another way is to send the Spdif to an older Lucid ADA1000 (20bit) , then send the converted analog signal to a Rane 8ch buffered splitter, which sends signals to the compressor and reverb , then back to the soundcard's analog INs, via the effect's analog I/Os.
    The idea for doing it this way is I can recieve the effects on different channels in my host CubaseSL (4 analog INs), plus have 4 extra signal outs (Rane will give me 8 total).

    Qs:

    1) Are the different bit depths in a chain going to need special attention?
    2) If I go with the D/A (second idea) , am I using way too many conversions and degrading the signal unnecessarily....(Lucid's D to A, and the effect's 2 internal conversions, then back to soundcard)??

    OK,
    I'll ask it this way. Which is better?:

    #A:

    24 bit digital OUT from soundcard, to an effect's 18 bit IN, and back to soundcard's digital in.

    or

    #B

    Soundcard's analog OUT , to outboard's analog IN, and back to soundcard's analog in.

    ?????
    someone's gotta have an opinion.

    option B is better

    A will get you a 18bit signal going IN, whereas B will give you 24 bit after A/D conversion.
    (i might be wrong, but hey its 1:32am and im tired)
    option B is better if you dont go through that same 18bit effect u talked about in option A. (itll still process the sound at 18bit no matter if it gets analog or digital input..)

    still with me?
    i am completely lost:p
    DONT ASK THESE THINGS:) sorry

    how about buying some extra bits for that 18bitter effects thing?

    i have a couple of (or should i say a bit) bits left of my last cd-listening experience. (as a matter of fact i have 8 bits left) wanna have some?




    am i getting too caught up in this audio-stuff?
