Changes in frequency response and their effects on sound

[plonter]

Hi all. while listening with my EF1 (and tuberolling ofcourse), I had a thought...which is my question to you guys.
are all the effects in sound like: soundstage, soundstage image, deepness, "lushness" of the music....and so on, are actually related to changes in frequency response between different gear/equipment?

for example: when i comparing a mullard tube and a tung-sol, there is obviously a nice audible difference in frequency response between the two, but are the other effects like soundstage and imaging are related only to that...? or maybe there are other things that create this magical effects that i don't know of.
please enlight me on this.
by the way..as you can figure, I am not relating to dynamic or other similar effects (speed, slowness) that are usually caused by better power/electricity and such. but if those are related also than I would like to hear about it.
thanks!

My opinion is:
Some of these terms are related to certain frequency response changes, others seem to be completely subjective.

There are no magical effects. If you hear such 'magical effects' please go to a doctor.

Now I don't know much about tube amps.. but imho one amp should have the same FR like another, i.e. flat.

That was helpful. No, really.
