SPEAKERS THAT SOUND ALIVE & DYNAMIC AT LOW LISTENING LEVELS

Op, just one more consideration:  Don't forget noise reduction.  You haven't specified your room acoustics or what you are using to reduce signal/source noise.  My goal is to attain a complete black background in the listening space, so that the sound shines through.  I find isolation/dampening and power conditioning help make a significant improvement in enjoying music at any volume level.  I've worked many tweaks into the system just for that purpose. Also, it makes a difference what time of day or evening I listen.  Evenings are flat-out the best for me.  But early mornings can be also be good, as there is, theoretically, less noise from the power grid coming to the house.  The right equipment is vital, but if you  want to "feel" the music at low volume nearly the way you do at higher levels, I suggest you put work into reducing noise, as much as finding better gear.

RC + PEQ from Wiim, possibly with a Umik-1. You could EQ the L/R channels separately as well as the subwoofer to achieve better integration of the system. Minimize possible phase shift with proper settings in Q, slope, target curve, and so forth. Very effective. Not compared to the Loki Max yet, but I believe the digital EQ coupled with RC is more precise / effective than analog EQ.

Right now, at 5 AM, my room's ambient noise is about 25 dBA, and I'm listening to my system at 50 dBA. The low frequencies below 100 Hz are boosted by about 5–8 dB (I limit it) using PEQ. The bass notes in this setting are clean and articulated. The overall soundstage shrinks, but hey, let me know if you have a better way to maintain a similar soundstage at this low volume level.

I agree that hearing aids should be your first upgrade. A nice tube preamp might be next step. 

@deep_333 I have long been intrigued by that speaker pictrued but have never heard it. At 103 dB/watt is should excell at low volumes. I do worry that it doesn’t have the mid bass driver that this manufacturer usually uses. However, the designer prides himself on a flat frequency response so I’m sure he has it figured out. I do have a lot of experience with this brand (although not in my system right now) and the low mass midrange array is one of the best upper midrange performers I’ve ever heard and it does sound great at low levels.

Try hORNS out of Poland. Beautifully engineered and designed speaker line that give Avantgarde a run for the money.

I have the hORNS Universum MK4, paired with Jeff Rowland 925 monos and Rowland Coherence II preamp. Sounds amazing at low volume regardless of the input.
