Could you please elaborate?
yes, but in what way?
as far as value goes, an XITE-D is about $300 more than a 14dsp card, but it's 2 1/2 times the power. an XITE-1 is about the price of 2 1/2 14dsp cards, but it's 6-10 times the power of a 14dsp card, wplus it has a really good pair of mic pres with hiz inputs.
it's hard to elaborate about the sound. i would hope that it would suffice to say that the XITE is more transparent and has a much lower noise floor. in addition because all the dsps are on the same board and because there's less chance that a big device would have to span more than one dsp, there are less potential phase issues with an XITE.
the reason for latency is that the processor needs time to do it;'s calculations. the cpu does much more than hand the audio to the Scope card and receive it back again. even with multiple cores handling multiple threads, it can only do one thing at a time per core. for realtime work, that means doing a bit of a job, moving to the next job and so forth, hopefully arriving back at the first job before the time runs out for playback. if it's too late, you get a dropout. there is a physical limit to just how much work can get done.
i hope this helps...
