Vandersteen fans..need your input (TREO CT)

Hey Guys, I love my TREO CTs, but I feel like they don’t really start to shine until I crank up the volume to 85dBs or higher. I feel like the details are missing at lower volumes. I know I have a lot of acoustic issues in my space, but generally speaking, at what volumes do you guys listen to your system. Just to give you an idea of my system, I’m using an Ayre AX-5/20 integrated, Aurender N100H streamer, Denafrips Terminator DAC (also an Ayre Codex DAC), AQ Earth XLR cables and AQ GO4 double run bi-wire speaker cables. Any of you guys do low volume listening...like the when your family is a sleep. Any general tips to improve the low volume listening experience? I suspect I would benefit the most getting room treatments but it’s not an option for me at the moment sharing the living room.  Thanks in advance.
Also, check out this link on youtube, it’s rare to see TREO CTs in videos on the web.
