My system / room is great at low volumes. When I turn it up I have to use a lot more imagination to get the thrill. The room is 8,000 cu ft, and its acoustic response causes the music to sound stressed and hyper as the pressure goes up. I have exonerated every component by swapping in substitutes, concluding that the room is the trouble. Installing enough permanent acoustic treatment to fix it properly is impossible because it's the living room, and my wife doesn't like a "cluttered look." I did prove the room was the problem by laying down half dozen comforters all over the floor. Before I learned the importance of the room, I upgraded everything in my system, at a substantial cost, and even sent crossovers and drivers back to speaker mfg for characterization and checkup - all was well. With the upgrades the system sounds LOT better now, but the room is still there, just keeps laughing at me, "You can never win. HAHAHAHAHAHA" So I'm learning to enjoy quiet listening, and negotiating for a better location. I will have to re-engineer the system from scratch to achieve what I desire in this house.
We could have bought a house with a full basement when we moved 2 years ago. The property we have is very nice, and better than what a basement lot would have been like (hillside near woods) but a basement would have allowed construction of a dedicated room with full acoustic treatment, into which I could install mid-fi level equipment and have an equally positive experience to what I have now. Frustratingly, an audio friend bought a house by same builder, next town over, with full basement, built on flat ground. haha! It's a crazy world.
I have heard a system at my local dealer that I really love. Great high end equipment, in a dedicated room with decent room treatment. I aim to have a system like that, but this year I have come to understand that it would be foolish to spend big money on a such a system without a room specifically set aside to use it to its fullest potential. I will instead aim to create a smaller system of equal quality to what I have now (but maybe less bass) in a smaller room whose acoustics I can better control.
