The Low Volume Loudness Dilemma

I love the power and detail of music played at what I call "Actual instrument volume" which is pretty loud and dominating. 

I like music in the background when I'm reading or entertaining. The problem is that the fullness and richness is thin to gone at low volume. This seems to be the case no matter how much a system costs. I listened to a Burmester rig driving a set of Wilson Alexx V speakers in a perfectly tuned listening room with cabling that costs more than my Lexus and the "missing music" at low volume problem was there too. $350,000 in gear couldn't fix it. 

I did the unthinkable - I bought a DBX 2231 equalizer off of eBay for a couple hundred bucks and messed around with the sound curve. Viola! "Loudness"!  I know this is sacrilege and may cause excommunication by the purist class but I am able to get full rich sound at low levels. The Eq also compensates for the anomalies in my listening area (large great room with other rooms connected to it.)

I don't have the square footage or budget to build a proper dedicated listening room with all the sound management treatments so I'm "making due" with what I do have. 

Does anybody have some guidance or constructive thoughts on how to get full rich music at low SPLs?

The third is a Loki Max remote EQ in my main hifi pile...this thing is brilliant.

I had a Loki Max on order when you wrote this; got it two days ago and have been fiddling with it. I agree completely with your assessment! My initial setup is to use the presets to approximate different equal loudness Fletcher-Munson curves.

The loudest I typically listen is about 80 dB SPL, but I do a lot more listening in the 65-70 dB range. With the Loki Max, I now can dial in the appropriate F-M curve to have a richer, more detailed soundstage at lower volumes. 

I hadn't really thought about it before, but F-M curves lead to the logical conclusion that, if your system is truly linear at all listening volumes, you can optimize the sound for only one listening level. The others really need to be corrected using EQ based on the science of equal loudness perception.
