I tried making an IR of a speaker sim VST but it sounded noticeably duller than the plugin. is this maybe because of the phase information being tossed out when it's made into a zero latency IR? I should try just using an impulse instead of a sine sweep next time
update: tried an impulse, nearly identical results. suspicious… maybe the plugin is doing something *after* the speaker convolution that gets disabled with the preamp or poweramp?
