The best reference is live music


For those of you who love classical music and care about imaging in your audio system, I recommend that you check out a San Francisco area group called Voices of Music.

They video record all of their performances and have most all of it on YouTube and free to access.  They are extremely well engineered recordings and more than worthy for the very finest audio systems.  What makes these recordings especially *useful*, as well as enjoyable, is that being video, you can see where all of the musicians are.  The best reference in audio is live performance.  Does  your system do an honest job of recreating the live performance?  Does your system give an image that at all matches what you see on the video?

Beyond this issue, Voices of Music is worthy to experience because they are very different from the large symphonic performances that most classical listeners hear.  Instead of the SF Symphony with 100 musicians, Voices of Music will typically have about 8 to 12 players.  There are some larger ensembles and some smaller.

They are an "early music" ensemble.  Just as rock 'n roll evolved from the early 1950's to what we have today, what we call classical music evolved as well.  The instruments evolved too.  A 19th century violin (what the musicians call "modern") has a neck pulled back, has steel strings and is engineered to be louder than an 18th or 17th century violin, which has a straighter neck and gut strings.  They are in fact, different instruments.

An 18th century instrument will articulate better.  The bow is lighter and faster than a 19th century bow.  Trumpets of that period had no valves.  Neither did French horns.  Flutes were typically wooden and had open holes.  That period also had instruments completely absent from "modern" orchestras.  If you haven't listened to a 1st rate early music ensemble, you're in for a totally new experience.

I just had a long post disappear in the ether.  The OP is referencing the HIP movement.  These instruments do not “articulate better “ and sometimes can sound terrible.

Small ensembles might be easier to record, and spatially place the instruments on playback.  I think it’s more difficult to do this with a full orchestra without unnaturally spotlighting certain instruments 

@mahler123 "HIP movement"?   What is that?

Small ensembles do record more easily as your listening space is more their size.  Most of us do not have a listening space the size of an auditorium.  As I mentioned earlier, the first time I heard the Infinity IRS V, it was in a hotel lobby area and it was playing an orchestral recording.  The columns were a good 12 feet to 15 feet apart and it really did sound like a symphony in front of us.  So thatʻs all you really need to faithfully reproduce a full symphony, a major floor standing loudspeaker system and a space the size of a hotel lobby.

This link is to a recording of my wifeʻs string quartet done with microphones in an ORTF configuration.  I recorded this with two different sets of microphones so I might compare them.  Iʻm curious as to what you think of each.

@russbutton The audio recording with the Oktava microphones sounds better to me because the sound has bite, more inner detail, and overall is more resolving. But to the majority of the “audiophile” community, the smoother and more “analog” sound of the audio recording with the Behringers microphones may be more appealing. 

I assume that these are raw microphone feeds without processing. If they are then this exercise perfectly illustrates the point that someone in the audience would hear the “fuller” rolled-off sound as rendered by the Behringer microphones; while the performers would discern that the audio recording with the Oktava microphones is a better representation of what was heard that day.

You were obviously there, which set of microphones’ audio recording best conveys what you heard that day?

Take this simple test.  Find a hi hat.  Any hi hat will do, it doesn't need to be a top of the line one with Zildjian cymbals or similar.  You do not need to be a drummer.  Hit the hi hat, preferably with a drum stick.  It will have a sound.  You can have someone else hit it while you stand back so you hear the difference between being right at it and away from it a few feet.  There's not a big difference, so much for close mic-ing.  Now try to record it.  Let me warn you, though, that the microphone hasn't been invented yet that can accurately record a hi hat.  Now if you can't even get a simple hi hat right, how can you expect the whole band to accurately sound life like?  The simple answer is:  We're working on it.  Be happy, it's all good.
