Dazzdax,
One thing I think I would say with confidence is that you won't get holographic imaging if the sonic queues needed are not in the recording even with tubes.
If that's what you're hearing, its encoded in the recording and your system is decoding it and your room acoustics are enabling you to hear it for what it is.
Tubes may add the "bloom" factor which can sound pleasing to many, but it is not the same thing.
