some thoughts- if you just came from a high-noise environment such as work or the noisy highway commute, your ears will take a good while to re-adjust their fletcher-munson loudness thresholds. just like how your eyes [when exposed to bright light] take a good while to adjust to low light, so too your hearing must similarly adapt to quiet after loud noise. so wait at least a half-hour before you listen to music after work. also if your room is too crowded/densely furnished/carpeted/upholstered, that will interfere with low level detail retrieval in my experience. you need room for your speakers to bloom. you also need to live in a quiet house in a quiet neighborhood, your kitchen needs to have a door on it [fridges and freezers generate a LOT of brown noise], you need to turn off your central heating/cooling while you are listening because they generate lots of brown noise as well. do these things and suddenly you will find that your speakers now sound as though the blankets have been removed from them. you will be amazed at the sonic fullness and details you hear.
Recommendations for speakers that sound great at lower volume levels.
I have a pair of Harbeth SHL5 Plus and they sound wonderful when I crank them up. But at moderate to low volume levels they sound disappointingly flat and unengaging - instruments are less palpable, bass has less bloom, and soundstage has less air and dimensionality. I drive my speakers with a tube integrated - a Line Magnetic 845 rated at 26 watts of power. My Harbeths are rated at 86db. Would a higher sensitivity speaker be helpful? Or how about a good quality small shoebox sized pair of speakers coupled with a subwoofer? Or not. What speakers are going to deliver music you can feel at low volume levels? What say all you wisened audiophiles?
