In the post "What are the most important audio components?" a few years ago, I said that we need to understand the various audiophile "domains": audio hardware, room acoustics, quality of your music, and of course personal mental engagement. Each of these have a part to play in the achievement of and personal judgment around sound quality.
Of those domains, it's hard to speak about personal mental engagement as this is a highly individual exercise (and related to one's auditory acuity). The quality of the music we listen to again is related to not just personal preferences (like genre) but also what mastering quality and variants like hi-res, multichannel, and on what format (SACD, vinyl, etc.) the record label makes available of our favorite albums.
It's always tempting of course to get excited about audio hardware - the latest toys. For example, recently, I heard that Andrew Jones has another ported box speaker design with paper/fabric drivers, this time with a coaxial tweeter+midrange that's based on field coils / electromagnets, paired to the permanent magnet woofer at something like USD$34k. While I'm sure this could be a compelling design for many, I think we can also recognize that these days, as equipment fidelity has improved significantly to the point where a simplistic "high price = high quality sound" equation no longer works, it's maybe wiser to direct our attention to the other domains.
This then leaves the very important issue of sound room acoustics, an area that we can all to some degree optimize (see also previous discussion on the sound room). I have heard it said that the sound room is the "foundation" from which we build our hi-fi sound system. As with any project, without an adequate foundation, no matter how great the rest of the system may be, you can only achieve a ceiling of performance dictated by the limits of that foundation.
In this post, let's dive a bit deeper into the importance of typical domestic small room acoustics and general principles around achieving good sound quality.
