Why don't more recordings have soundstage outside of speakers

mahgister I meant averagely good acoustically which is not measurable but I think most would know what I meant. if you want to make everything sound like mystery and magic then go ahead, there are some basic acoustic principles that are worth trying before you turn to guesswork. I’m not even sure what ’an experimental fact in acoustic’ actually means.

I get your point...But a room with some panels is not a room under control necessarily in most case... Sorry....

My point is about the acoustic control of a specific room...

And it is not my desire to sound like "mystery".... Acoustic is not magic but an experimental science...

My listening experiments are a gradual sets of improvement not a one day "guesswork" job and they are based on some acoustical experimental fact...


Here one who inspired me:






«. A new physical measure for psychological evaluation of a soundfield: Front/back energy ratio as a measurefor
envelopment.M. Morimoto (Environmental Acoust.Lab.,Facultyof Eng.,KobeUniv., Rokko,Nada,Kobe,657Japan)and
K. Iida (Kobe Univ., Kobe,657 JapanandMatsushitaCommun.IndustrialCo., Ltd., Japan)
Broadening is one of the important characteristics for the psychological evaluation of a soundfield.
Several investigations
indicated that broadening was comprised of two elemental senses, i.e.,auditory source width(spaciousness) and listener envelopment [M.
Morimoto et al., Proc. 13th ICA, Belgrade2, 215-218 (1989); J. AcoustSoc.Jpn.46, 449-457 (1990); and Hidaka et al., J.
Acoust.Soc.Am. 92, 2469 (A) (1992)].

They inferred that the degree of interaural cross correlation of lateral reflections correlated
with envelopment. This paper,however, shows the results of psychological experiments that envelopment is affected by the energy ratio of reflections coming from the front of the listener to those coming from the back of the listener,even if the degree of interaural cross correlation of the lateral reflections are equal. Namely,envelopment grows as the energy of the reflection coming
from the back of the listener increases. This result suggests the need to measure the ratio which has never been measured.»

Do electronics ; power amplifier or preamplifier , have any effects
on the soundstage , holographic sound, etc. ?
I may change my integrated amplifier and wounder if I could only buy a power amp. I only use the preamp section of my integrated
for my Lumin streamer. But I could connect it directly to a power amp. using Leedh processing.
No need for the preamp. Section then.
Would I loose anything regarding deepness , soundstage ?

Sorry for the misspell

pragmasi, I prefer a pan hard and delay. That simple pan and invert gives a moving image based on signal content. Delay gives ya better control. Gotta be in the right spot for it to work well. With headphones no need for such crude instruments. No mystery or magic if ya know what is going on and no need to make things up.

For sure they will have an big effect....

Acoustic control does not replace good electronics design pairing, no more than good electronic design could ever replace acoustic control....

I am not an audio engineer, only an average person like you, trying for the last 3 years very hard to create my own system heaven...

I succeeded then it is possible even at low cost...

But you must chose the right components first for sure....

Me i begin to really progress ONLY AFTER i have pick the right basic gear for me and for my purse...Speakers,amplifier and dac....

After that to take care of the 3 working embeddings dimensions: mechanical, electrical and especially acoustical...





If you need advice for pairing amplifier and pre-amplifier, i cannot help you here....
Ask these question to a guy like atmasphere, he is very knowledgeable for all thing related to amplifiers....

His posts are very good....

My best to you......
