Turn down the Volume!

@dain , It is not that complicated. If the mixing engineer is mastering at a higher volume he is going to keep the bass and treble a little lower to get a balanced sound. When you listen to it at a low level it sounds dull and bass-less. But, if you turn it up to the volume the mastering engineer was mixing at, it sound fine. Again, all this is based on the Fletcher-Munson effect. Every recording has a "right" volume level based on the type of music and the way it was mastered. The way around this is called dynamic loudness compensation. TacT Audio is the only company to have done this. In the old days just used tone controls. Now, some of us have digital EQ. Me, I just turn up the volume till it sounds right:-)

@phusis , an actual live acoustical reference certainly is the goal, at least as far as I am concerned. The problem for all of us is that a live acoustical reference is a moving target and ones that are not electrified into oblivion are hard to find. One of my favorite references is the conservatory string quartet. If I were to record one I would want the reproduction to sound exactly like that, room and all. Jazz in the right venue offers another opportunity for a realistic reference. It is easy for any great system to outperform most rock and pop concerts as they are in most instances distorted mono. I suppose I am looking for a rock concert with the imaging of a live string quartet, but with the bass, power and dynamics of rock. This is the audiophile me talking not the music lover me. The music lover me will gladly listen to a 78 of Enrico Caruso. I am not quite sure which lover John is speaking for. The general public is routinely astounded when they hear a big system. As he explains, many of them never knew systems like these existed. When you tell them the price they think you are crazy, probably true. Do they enjoy it? Sure, like any amusement park ride. They are certainly not making or even thinking about an analysis of the performance for accuracy. There is a scale of accuracy. Some systems (includes the room) are more accurate than others. Accurate and enjoyable are two separate issues. John is talking about enjoyable which more or less comes down to taste. Accurate is that string quartet sounding exactly as it did at the live performance. There are millions of almost accurates , but only one accurate.  Some of us prefer a more surrealistic version of reality. I will alter the sound somewhat to suit my own taste, to replicate my memory of the live performance at reasonable levels. It always is a matter of memory and we all hear music differently. I have yet to see anyone AB a live performance with a recording of it. We have no trouble remembering what we heard, but we have a real hard time remembering what we heard sounded like. There are so many confounding factors which is why there are so many opinions regarding the quality of music systems. John thinks if it sounds good, if it is "enjoyable" then it is valid. This approach is fine for most people. IMHO this is an avoidance tactic and certainly a lot less stressful than that search for the one accurate. This has nothing to do with validity. Any old which way you can enjoy music is valid. If you are looking for accurate you are in for a rough ride.

To all a Happy 4th!

Volume is one area which makes people think cd is better than streaming. Most streamers are low on volume and it’s only once you’ve adjusted the fixed volume to higher where things change drastically. 
 

now as much as volume is important, the listening environment is just as important. In a treated room, you’d enjoy your system. Volume is key but the environment is very very important. I can literally hear the sound from the highway as I type this. How do I expect my system to sound good under such conditions

@amosm  If you don't want to hear your car rattle, turn up the radio. This is called masking. The same holds true of your highway noise. Play vinyl which has a higher background noise level and turn up the volume till you don't notice the highway.\

Your only other option is to move. I 

I know of no house that is absolutely quiet. Mine certainly is not but, it never bothers me until I am taking measurements then I turn everything in the house off.

I suspect that the reason high-efficiency speakers tend to sound more dynamic than low-efficiency speakers has to do with thermal compression.  For any given output level, low-efficiency speakers have to run more power through the drivers, with a larger portion of that power being dissipated as heat vis-a-vis  high efficiency drivers.  That heat actually increases the resistance of the voice coil and this reduces the power that can delivered to the coil, thereby reducing its sound output.  Hence, there is more of this sort of compression of louder signals with low-efficiency speakers.  That is why high efficiency speakers sound more lively at any given sound level.  I think they sound particularly lively at low levels.
