(Though I'm still wondering if modSBM1> microtracker at 16 bits would be better than straight into the microtracker at 24 bits, skipping the SBM1 entirely. We shall see.)
interesting point...
anyway - i think i found the solution. coresound is going to do the cable for me. i sent them one that had broken today, and len said he would fix it and shorten it for me (as i only need/want 6 inches or so - in fact, it was the fact that the cable was a meter in length that caused the extra stress on the cable, where it broke)...
i also think that the pda i was using is sh*tty and slow, and that i can find another pda that is more powerful to do the job for me. so leaving the dongle the way it is might be a good call. i was just curious if it could feed a standard spdif coax rca connection just by getting a female mini > male rca barrel adapter from rat shack. and you say that i can. that is cleaner than the 7pin/coax cable...
and the custom dual male 7pin cable len is going to make for me will keep me straight and prepared for use with dat, again, in a very clean way (so i can put the dat on top of the sbm1, put a hair tie around them both, and stick the whole thing in a jacket pocket - it is those extra long cables that get in the way when doing that sort of thing
)...
as for tuesday, maybe the cable will be here in time, maybe i can borrow a local sbm1 for the evening, or maybe i will have to do the dongle > barrel connector > oade 7pin > d100. could be rough, but workable in a pinch, i guess...
anyway, thanks for all of the input and help...
