It was certainly low. I could remeasure with the doors open to the equipment but likely in the 30s (db). But at my listening position, during quiet scenes

I didn't really sound like a fan but when I powered it down, I could hear a layer of sound disappear from the listening position (8 ft away). Granted these are small improvements but they add up. Now, when the system is on, I can hear myself think - and it is odd feeling in the absence of other no audio noise. Odd in a good way. Subjectively, the dynamics, dialog, etc are all improved.
I don't have any equipment that can measure so low, but needless to say, I can't hear any equipment now, no HVAC noise but if i shift my body in my chair, the cushions moving is the loudest thing and can be heard all over the room!!
It's hard to quantify or qualify but the sheer quietness is certainly adding to the overall excellent sonics.
