I agree with Nilthepill and found much improved height in the near field after moving the listening position forward. Also, try using track 11 LEDR of Chesky JD037, JAZZ SAMPLER & TEST VOLUME 1 to check for and eliminate first reflection problems.
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?
