Low volume listening dynamics

At the risk of upsetting the true audiophiles......I have two separate solutions in different rooms for low volume listening.  In my office, I use the Adam F-5 active nearfield monitors, and their built-in adjustable treble and bass EQ setting to boost low end bass response and high end treble response.  In the family room (which is my main listening room), I use an Emotiva XMC-1 sound processor and have set up a dedicated EQ preset with individual frequency adjustments to optimize for low volume listening.  The older we get, the more 'help' we need to compensate for low volume listening.  In the past, I have liked only one "Loudness" feature, and that was on an old Yamaha receiver I had I college.  I don't like the Loudness feature on the XMC-1, but I do like the parametric equalizer that I can tune to my own flawed ears.  Good luck.

Relating speaker sensitivity to low volume detail seems incorrect to me.  One of my systems has really excellent low volume realism, and the speakers are the lowest efficiency of any I own - 86 dB.

glassrd, no upset at all. I have been doing essentially the same thing for 20 years. You have just programmed your own loudness compensation.
The unit I have allows you to program 8 loudness compensation curves each one active in a specific volume range then the unit jumps from one curve to the next as you adjust the volume. Dynamic Loudness compensation. 

Have to second the opinion about the Schiit Loki. Vacuum tube system with sensitive speakers (Audio Physic Scorpios 91 dB) sounds more satisfying, but certainly not live, at lower listening levels. At normal levels the Loki is bypassed. 

Adam F5 is an interesting new thought to consider, thank you.
