Will the amp built into my AT2020USB+ mic drive these effectively? Specs are 130 mW (at 1 kHz, 10% T.H.D., 32 ohm load)

130 mW into 32 ohms corresponds to about 2 V. According to nwavguy (http://nwavguy.blogspot.com/2011/06/sennheiser-hd-650.html), HD650 is supposed to be 103 dB SPL at 1 V rms, so the peak output should be about 109 dB SPL.
