Okay, after spending the last half hour doing A/B tests of 160kbps, 192kpbs, 256kpbs, and 350kbps .ogg files, I don’t think my ears are good enough to hear that much of a difference. I think I’m going to go with 256kbps, but I’ll give everything a listen at home through speakers and headphones and then decide. Maybe my ears suck, or maybe it’s the noisy sound card in this machine. We’ll see.
