Mike,
That's what I figured. One thing I noticed from CDPs (and audio electronics like DACs, Preamps, and Amps) is that the higher you go up, the main and consistent difference is the blackness and the 3D-ness of the sound.
A lot of the "wide soundstage and spacious sound" I find has a lot to do with the gain of the unit/system. And I find that I gravitate ultimately to whichever gives me the lowest noisefloor and the best 3D effect.
After all, life is in 3D. Or is it 4D? I forget... lol. :)
