My listening room is small, so I am limited in what I can do with it. Have been working on improving the sound for a few years.
I have recently added the Lumin A-1 music streamer, and it has changed my opinion about digital music. Listening to my collection of ripped CDs via my network server and the Lumin is finally enjoyable on the scale of listening to vinyl; It is that good. I have had a many DAC and CDPs in my system over the years, and none has been as good as the Lumin.
I too have a small room, actually smaller than yours. I just added a single sub and like you absolutely love what it added. I am surprised how much low freq information I was missing, considering I listen mainly to acoustic and folk. I am much more engaged now. The improvement has been so good that I am now toying with the idea of adding another sub. Have you considered this? Also curious if you have thought about measuring the freq response of your room? I did it quickly using an SPL meter and some test tones. This helped me tremendously in terms of positioning my speakers. Even in my tiny room where my options are limited, I got huge improvement by changing my speaker position.
