Just integrated the E50 in my setup: Node as input (fixed volume), connected via USB to the E50 (used to control the volume), then ARX RS-1 as HT bypass, and AHB2 with mid-gain settings (17dB amplification). I’m however a bit surprised by my listening level, typically -40dB. Is my understanding correct that 0dBFS then corresponds to 42.5mVrms at the output of the E30 and 300mVrms at the output of the AHB2? My loudspeakers have a sensitivity of 89dB SPL at 1m with a 2.83V input. So the maximum SPL level that can be reached, with the E50 set to -40dB, is about 70dB SPL, which seems very low. Mind you, it is in the same ballpark than the peak SPL measured with an App-based SPL meter when played hot-mastered music (Adele)…
