Hello dave_b,
Excellent post! I agree with you completely.
My favorite main characteristic of a high quality home audio system is its ability to create a very realistic three dimensional stereo sound stage illusion that is as wide and deep as possible. This very realistic three dimensional quality also requires that the individual musicians’ images within this overall soundstage are being perceived as appropriately sized, solid, stable and palpable for the perception to be created that the entire musical performance is taking place in your room or that you’ve been transported to a very good seat at the original venue.
dave_b:" Another trick is using as little toe in as possible while maintaining a solid center image, which increases dynamics and soundstage size/dimensionality. Using components that can bridge the gap between overly detailed and euphonious sound is key...live music is an elusive animal somewhere in between. Get all that right, plus a good room and either format can move you emotionally!"
I agree with these statements, too. As I believe almost every experienced audio enthusiast can likely attest, while attaining the physical parameters and aspects of a virtual reality stereo sound stage image in one’s room is very challenging. it’s still only half the battle, since as you wisely stated: "Using components that can bridge the gap between overly detailed and euphonious sound is key...live music is an elusive animal somewhere in between. Get all that right, plus a good room and either format can move you emotionally!"
That sounds about right to me, I definitely agree that good quality vinyl systems can also create high quality stereo sound stage illusions. It’s just been my experience that utilizing high quality direct to hi-res digital recordings and playback equipment are significantly better at facilitating, and even enhancing, these high quality stereo sound stage illusions than vinyl playback is capable of.
I believe hi-res digital’s higher signal to noise ratio and higher detail levels, combined with its inherent lower distortion and lower surface noise levels, are key factors in its ability to create significantly more realistic and palpable virtual reality stereo sound stages.
Lastly on a related topic, I’ve also discovered that the accurate reproduction of the power, impact and dynamics of the bottom 2 octaves, bass technically from 16-32 Hz, in a home audio system and room is perhaps the single most important characteristic in distinguishing between a home audio system being perceived as decent with an acceptable facsimile of good bass and one perceived as exceptionally good with bass that sounds and feels like it does when played and heard live in person. High quality deep bass is typically the most difficult frequency range to get sounding and feeling right and natural in a room.
It also seems to me that good bass performance, in general, is one of the most neglected portions of the audible frequency spectrum in home audio systems. I’m not certain exactly why high quality bass performance is not more of a priority for more individuals; whether it’s due to a lack of space for the required multiple subs in their rooms, a lack of willingness to spend the extra funds or perhaps just a lack of knowledge of its importance and how to attain it.
