My normal volume on the Denon during the day time is -12dB to -15dB, depending on the song.
At night time, my volume goes down to -25dB.
So I've listened to both the Orions and Salon2 @ -25dB at night.
I think the Salons still have the slight edge on resolution/detail. I think dynamics is about even at this low volume level.
So which speakers are you considering?
