Try listening to near field, with your ears at tweeter height. In my experience that is how I perceive Diana Krall singing over the piano and bass. Further away I sit,lower the height.
Soudstage Height?
The other night I experimented by using my Jolida 502B integrated as a preamp running through my well renowned solid state power amp. Things sounded okay but the biggest surprise was the amazing drop in the height of the soundstage. I went from tilting my head ever so slightly back to envision Diana Krall doing "Garden in the Rain" with the JoLida doing everything, to seeing her shrink to the height of my Kestrels via transistors.The depth seemed about same though. Can somebody explain to me what gives a soundstage height?
