What is the One Test Track That Tells You Almost Everything About A System?


My recent thread comparing Tidal and Qobuz generated a lot of great discussion so I thought I’d try another question for the group.

If you had to choose one track that tells you almost everything about a system, what would it be?

I’m talking about the track you play when:

• evaluating a new component

• setting up a system

• showing someone what your system can do

Ideally it reveals several things at once — imaging, tonal balance, bass control, dynamics, etc.

One of mine is Patricia Barber – “Nardis” from Cafe Blue.

The recording exposes bass articulation, room ambience, and micro-dynamics almost immediately.

I’m always looking for new reference tracks, so I’d love to hear what others use — and what specifically the track reveals about a system.

 Yarlung Records circling tones. If you can hear the tones above and behind your head, your speaker placement and room acoustics are in total synch.                   

Take the A train on Ray Brown Trio's album Soular Energy   (Analog Productions 45 rpm)

The Look of Love on Dianna Krall's album Live in Paris    (ORG 45 rpm)

Lime House Blues on Jazz at the Pawnshop    (Prophone)

Birdland on Weather Report's album Heavy Weather     (ORG 45 rpm specifically for soundstage size)

Beck from Sea Change the Golden Age and then the beginning to Paper Tiger.  There is so much going on in the opening track Golden Age but how that song comes to an end let's me hear and feel the center image really, really well.  Then the start of Paper Tiger taps into my system bass performance and clarity.   The second I would suggest is the opening song The Healer off of John Lee Hooker's album of the same name.  The drums sweeping across the soundstage always give me a thrill.  

There is no single piece of music and certainly not pop song able by itself to be a genuine test...( We must use many instruments  timbre and human voices as testing ground then after timbre test we must test spatial recorded cues as translated in our system/room ) 

 

For timbre testing among few others : i use often Bach orchestral suites interpreted by Jordi Savall....Top recording and a great variety of different timbre...

 

 

My prefered album test among many i knew by heart  is this one :

 

Kurt Weil : threepenny opera by Lotte lenya  only this version :

 Why this one :

For sure a top Recording technician was there ...

But also the location in space of instruments  and in front of it the singers walking, around the listener, murmuring to his ears when walking near him or going back on place, you must "see" them turning their heads etc... This album is perfect test for spatial cues...

If you dont see the singers walking and turning their head when singing or speaking or  hear some singers (male and female duo for example ) singing to your ears each one  on each side as if they were under your shoulder, your system /room is not under mechanical,electrical,acoustical controls. Nevermind the price of your system. Sorry . In a word the soundstage must be behind the speakers around you and almost behind you filling the complete room. I know it because i did it in my controlled dedicated room. (Price =peanuts, but real cost was 2 years of acoustics training 24 hours /24 i was retired and acoustics was my hobby)

Acoustics control rules audio not price tag....

 

By the way if you use studio trafficked sound instead of a live classical recording  you do not test your system/room at all... Why ?

Because a true acoustic test consist in the study of a translation (not a reproduction because there is always a trade-off implied) : the live recorded event timbre and spatial cues parameters   are directly translated  through your system/room specific acoustics parameters to your ears/brain...

Studio recording are not about acoustic translation of a live event but about sounds induced artificial effects...
