Seems to be OK there, safe before clipping yes, but still wonder if 250 Ohms is adapted, all blocks when added in presets give too low volume, always end up having to add 8 to 12 dB to get good volume. Hesitant to change headphone for the 80 Ohm version... hmmmmm
Note: am also doing these tests w/ single coils, likely not helping, colder mics than humbuckers...
