If a " system " cannot do this, I move on........

One of my favorite albums Romantic Warrior. When Chick (RIP) runs that synthesizer note down to the basement on Medieval Overture my piloerectors go nuts. 

Great recordings are not accidents, they are art. Great music systems are not accidents either. The very best are always intentional and they can take a multitude of forms arriving at surprisingly different but valid results. One characteristic they all have is the ability to separate instruments and voices in space with nothing but silence in between. "Talk About Suffering" is an acapella folk song on John Renbourn's A Maid in Bedlam album sung by 6 individuals with unique voices. This stunning recording will plant 6 individuals on a stage in front of you, the distance depending on the system. Each singer is an individual on stage with silence in between. Each so well delineated that you can actually listen to one singer at the exclusion of the others, a sonic hologram. In a less than optimal situation the singers become blurred together. The Cherubini String Quartets by The Melos Quartet on Archive is another example of near perfect imaging, each instrument clearly identifiable as an entity in space. Four individuals with one brain. Steely Dan,  Countdown to Ecstasy  is IMHO the best Steely Dan recording. On a great system it is an amazing ride.

In many instances, particularly large concerts (big venues) a great system can sound better than the live performance. I saw Tower of Power recently at the Hampton Casino Ballroom. It was a great performance but sonically it was a loud mono blur with boomy bass. The live 50 Years of Tower of Power album is a recent recording of the same playlist. The bass is detailed and authoritative. Each instrument and voice is clearly delineated. Turn up the loud dial and you are right there in a smaller venue with great acoustics. Eyes closed I can see the band on stage exactly where they were planted live, Blu Ray not necessary. 

Can a system based on horn loudspeakers perform at this level? You bet. But, the system has to be intelligently designed to perform at this level. It is 90% about the speakers and room. It is perhaps 8% about amplification and 2% everything else. Does the program source matter? Yes, the recording and mastering. Analog or digital, both can perform just fine if the recording and mastering are appropriate for the source. Anyone who boasts one or the other is biased. Digiphobes are an interesting group considering 99% of the modern music they are listening to is digitized. If the disavow all digital music they are going to miss a lot of great music that will playback on a great system just fine. 

I would not divide speakers into Horn, Dynamic, planar magnetic or ESL. I think it is more useful to divide speakers into point source and Line source as it tells you more about how the speaker is going to image. I prefer line source, dipole ESLs as I have been working with them for decades and am comfortable dealing with them in terms of room acoustics and amplification. If I were to go point source I would look seriously at horns because you have more control over dispersion. IMHO omnidirectional speakers are a PITA requiring more intense room treatment. 

As Harry Pearson defined it, it is all about finding the Absolute Sound whichever way you travel.  

@mijostyn, some interesting thoughts on the subject, and agree on the musical choices. IME, live performances that are amplified can be exciting, as seeing a favorite band live is awesome, but a smaller venue without amplification is " dabomb ". I have never heard a hifi system approach this sense of realism, and I blame the source ( recordings ), as I have stated many times in my posts. However, I enjoy every recording I listen to, because I listen past the recording quality, and envelop myself with the artists, and the story they are telling. With an audio system, the shape and size of the stage, the musician localization, and the distance between me and the band ( the imaging thing, etc. ), which is all important, becomes 2ndary to me, as I feel, the performance and the playing, is why I am listening. Many systems I have heard, can be very " spatial ", but do not connect me to the musicianship. You mention Chick as being the standout to you, but Stanley, Al and Lenny are all standouts. A great system, imo, allows you to hear them as individuals, and convey the togetherness of them as a whole. Thank you for your participation, and enjoy !

Hi @mrdecibel ,

Yes it is very important point you are talking about. The system which

help you feel interpretation. But sadly most of audiophiles don’t care about it as well about natural instruments tone.

Probably, because that, low sensitive box speakers (lack of micro dynamics and texture, sound dead) and belt drive turntables (at lease most of them - kill rhythm nuances) so popular today.

Glen Gould was interested in recorded music with the idea that it allowed the performer to get out of the way of the music, to quit being such a distraction to the audience. It's funny we now talk about our stereos getting out of the way of the performer. Some music is all about putting attention on the performer. Or maybe it's just some ways of listening to music are like that. I tend to think more like Glen, and perhaps that sets a lower, more attainable bar to make a system that's primarily designed to convey the musical message rather than capture everything about the event and performers in ultimate realism.  It also makes life easier because a lot of good music isn't recorded in a way that can make that happen anyway. For me, the equipment bar is still fairly high because I want clarity without frequency response  kinks (on or off axis) or obvious distortions and resonances that are going to distract and fatigue me, and I prefer a narrower than usual dispersion pattern down as low as I can get it, which necessitates a large speaker. The setup I have now makes just about everything highly enjoyable for me to listen to. Because of the narrow dispersion and relative lack of early room reflections it lacks the immediacy some are looking for, the sense that someone is actually in the room with you. Instead they sound like they're singing into the room from wherever they were actually recorded, through an opening that is less than perfectly transparent in a way that makes differences between recordings less bothersome. 

@mrdecibel , I certainly did not intend on excluding the others. I was only talking about one note!

I was a DJ at UVM's radio station. RTF played both Burlington and White River Junction during the Where Have I Known You Before tour. I got to interview the entire band and had front row seats at both concerts:)

My goal has always been to create the "live" experience at home. To create the size and detail of a live performance it takes line source speakers. Dipole ESLs are perfect but they have to go floor to ceiling. To get the power of a live performance you have to use subwoofers and a lot of power. But, ESLs? Are they not limp when it comes to volume and dynamics? Not if you take 100 Hz and under away from them and with the right amps (high power class A) they thunder. Get the subwoofers right and you can easily create all the sensations of a live performance. You have to have the ability to boost the low end at least 3 dB at 20 Hz. I do 5 dB. That is measured in the room at the listening position, not at 1 meter. With multiple subwoofers in a line array you can limit room interaction and get pretty even bass throughout the room. Line array dipoles only require sound absorption behind the speaker. You can almost entirely eliminate the room signature this way. Experienced listeners will initially think the treble is rolled off until they hear a few cymbals. All the high end is there but it is in focus and not sprayed all over the place by reflections. The "brightness" of the reflected treble is gone. The drop in volume off axis of the ESLs is very dramatic and very sharp. Sound Labs are designed to have a 45 degree axis. They will do 90 degrees for very large rooms on request. If you stand directly to the side of the panel all the sound seems to come from the front wall even with 4" acoustic foam tiles on the wall! 

If people are looking for the sound and sensations of a live performance in their their home system it can be done. If using point source speakers you will be farther back in the hall. With line source speakers you are right up front. Either way you have to have aggressive bass performance below 100 Hz, down to at least 18 Hz. This is where all the sensation is coming from. No bass, no live performance. Room reflections create a sheen around the music that ruins the "live" effect. It covers the space between the instruments and voices blending them together. Only clever room treatment will get ride of this. DSP will not.
