The fact that the music room has the greatest impact on the sound experience is constantly underestimated. Buying an expensive stereo system is no good if there is a poor music room at the end of the playback chain. Listening to even the best recordings can prove an ordeal in an acoustically imbalanced room, and any prospect of enjoyment is strangled at birth.
That is why builders of concert halls and recording studios go to considerable effort to achieve pleasant sound. If you care to make a simple experiment, you can compare the difference in sound between a low-priced and an expensive audio cable, and between an untreated and an acoustically balanced musicroom: you will be amazed.
