SPEAKERS THAT SOUND ALIVE & DYNAMIC AT LOW LISTENING LEVELS

@kjl1065 If you haven’t done this already, I recommend you treat your room with acoustic treatments before replacing your speakers.  I had my system dialed in pretty good in my 2-story family room after treating the room as much as I could.  However, I just moved my hifi gear to my newly finished dedicated listening room.  After my positive experience upstairs with room treatments, I installed ASC tube traps, 16 ASC Soundplanks for the side walls and 3 GIK absorption/diffuser panels for the back wall and it was amazing how the flutter echo, room boom, etc., was eliminated with these treatments.  I could hear more details in the music, at much lower db, that I couldn’t hear upstairs in the 2-story family room because I couldn’t treat the room like it needed to be treated.  It would have become an eye sore.  The proper room treatments will give any speaker the opportunity to showcase what the manufacturer intended.  I replaced a lot of gear over the years and never focused on my room with bare walls and few reflective glass photos or artwork hanging until years later.  I read about room treatments over the years, but just didn’t care to pursue it.  I was focused on the gear.  I finally bought room treatments a few years ago and that changed the sound of my setup dramatically.  Not treating the room was a big mistake and it caused me to swap out gear that may have been just fine.  Treat the room as best you can if you haven’t done so yet.  I like GIK’s prices, but they recommend tons of treatments and it becomes ugly and over damped if overdone.  ASC costs more, but their Soundplanks are tasteful and they don’t overpower the look of the room and the room still sounds live and not over damped.  The last piece of my puzzle is an area rug which is being delivered today!  This is just my experience and opinion.

Godspeed to you on your hifi journey!

I like this topic. In the real world don’t we tend to listen at modest volumes? Like others here I often listen at low volumes early in the morning while the house is asleep and not missing any detail or dynamics at low volumes is something I enjoy and now require with any system changes. I feel my current setup is superb at it. I’m using Cube Nenuphar Mini’s with a Line Magnetic LM845 Special and a pair of REL S510’s. Fantastic at low volumes and high as well. Most Friday or Saturday nights my wife and I listen and she’s a bass head and specifically listens to songs with bass. She gets a kick out of any track that makes the windows rattle. 
I’ve used other amps that also sound great at low volumes including First Watt and Primaluna. I think the commonality is speakers with good efficiency and tube amps or amps that are lower wattage but can deliver those watts regardless of volume. 

I listen to my large desktop audio system at very low volumes ~12/hrs/day. I've had quite a series of 2-way speakers on the desktop, augmented by a JLAudio e110. It's a 13' x 13' room, so this is fine. I can recommend 2 speakers that always satisfy at low volume:

• Pretty much anything by ATC
• Harbeth 30.1s

I have extensive experience with EQ. Please reach out to me. 

Bass and treble boosts are my forte and I can point you in very much better directions than Loki Max. I’ve owned it and it was greatly inferior to a pro analog piece I own for the use case you described
