fuck me.
after listening (probably for too long) to:
master DAT > headphones (DA-20 MKII > Sony MDR-7506s)
master DAT > receiver (DA-20 MKII > 20' Radio Shack coax > Denon AVR-1603 > Sony MDR-7506s and B&W DM302s)
transferred version (DA-20 MKII > 20' Radio Shack coax > Waveterminal 2496 > Wavelab and Sound Forge > wav > Waveterminal 2496 1/4" outs > Denon AVR-1603 > Sony MDR-7506s and B&W DM302s)
master DAT > sound card > receiver (DA-20 MKII > 20' Radio Shack coax > Waveterminal 2496 (analog out mixer set to DIGITAL IN only, -10 dBv > Denon AVR-1603 > Sony MDR-7506s and B&W DM302s)
of the same shows, SOAD 04-24-05 (sparge's modSBM-1) and the aforementioned local band (my modSBM-1), i have to say that there is, without a doubt, a serious problem with the digital in of my sound card. no doubt about it. believe it or not, everything sounds flawless (or ALMOST flawless - i might be imagining some crackling still in the SOAD tape, but the local band show - using MY sbm-1 - sounds fine... unbelievable) without the sound card. the difference between the Waveterminal sources and non-Waveterminal was distinctly and immediately audible.
well, blow me down. how fucking retarded do i look now?
while looking at the Waveterminal 2496 mixer, i noticed one more test i need to conduct: changing the clock source from INTERNAL to DIGITAL IN. could this, of all things, be the cause? we'll see in a minute...
there's one flaw in this theory, though. the soil tape i retransferred last week sounds clean. if the sound card is being screwy, then that tape, too, should have demonstrated the crackling noise...
