Hi

I am interested to hear which is your favourite CD
for demonstrating your systems' sound stage.

I would imagine a recording of chamber music or
something similar.

Regards
A

That's easy - Roger Waters - Flickering Flame. It's
recorded in Q Sound which is a 3D sound field from stereo.
We have on track 2 - Too Much Rope a stage coach travelling
across the whole sound stage L-R and then a little later a
F50 Ferrari goes the other way at full song. Oh and it's
not a bad album either.

Cheers TT


Joking? This is an "effect", and while it may be fun - even impressive
at times - there is absolutely nothing that makes it suitable for
demonstrating the sound field of a system. If anything it obscures it.

Well yes and no. A stage coach making a sound is a "Sound
Stage" :-)

Seriously now it does show very well depth and width of
"sound stage" and preciely placing objects in 3D space.

Lastly the OP did ask for a "subjective opinion" in "What
was my favourite CD". Yes this demonstrates very well a
wide deep sound stage that generally gets other people quite
excited.

What I prefer myself is any live acoustic stuff e.g Eric
Clapton Unplugged or the Corrs Unplugged just name two off
the top of my head. Also any Diana Krall, Norah Jones etc.

Cheers TT

Live acoustic is always likely to be better, depending how it is
recorded, of course.For me assessing a sound stage means that there
must be a sound stage to asses. That needs a live recording, not
something created on the desk.

Sorry to reply twice to the same posts, but make that 2D, not 3D.
There is no height to the images created by this method (how could
there be with stereo speakers?).

Agreed. I find multitrack/layered rock/pop recordings are usually very
tedious to listen to as there isn't that "correct place" in 3d space for the
instruments/vocals. BTW 6ch done badly is even worse :-(

Yes I agree in principal with what you are saying BUT (there is always a
but) the soundstage does have height factor of roughly centre to those
stereo speakers so therefore the sound does occupy 3D space all be it on the
narrow height side.

Further to this my main speakers are (a local custom built Oz brand)
http://www.equinoxaudio.com.au/produ...s/apogee.phpso at 1.5m tall
and the drivers symetrical around the centre tweeter I do find arather good
height dimension as well. Obviously we are not going to bouncing sound
effects off thr oof and floor though ;-)

Sure it has height, but that height is all to do with a dispersed
speaker source, comb filtering off the floor etc. It has absolutely
nothing to do with a sound stage. So no, the sound stage isn't
actually 3D as it would be if you had top and bottom as well as left
and right speakers.

Now that is a product differentiator! Something
for companies like Sony to follow up on.

Easily achievable with Ambisonics but it never really took off - and I
don't think any of the commercially available recordings encoded height,
though it is possible.

Why ?

"Soundstage refers to the depth and richness of an audio recording
(usually referring to the playback process). According to audiophiles,
the quality of the playback is very much dependent on how one is able to
pick out different instruments, voices, vocal parts, etc. exactly where
they are located on an imaginary 2D or 3D field.

Which is more than you can normally do in a live acoustic - well with
orchestral music anyhow.

I would suggest something recorded as simply as possible. That would
include any BIS chamber music recording. I particularly favour the
"Durufle Complete Choral Music" by the St Jacob's Chamber Choir".

Trinity Sessions by the Cowboy Junkies isn't bad either (recorded around
a single Calrec Soundfield mic).

Roy.
