Solid state amplifiers and sound stage, especially front to back "depth"

I've been enjoying my trial period with the Van Alstine SET 400 stereo amplifier. When I'm done and have collected my thoughts, I may write up a summary.

In the meantime, a question for folks with more experience. I've noticed is that the amp produces a sound stage that is nicely defined and articulate from left to right, but not as much from front to back. (My Adcom was also unable to create sound stage depth.) I know my room is capable of that sound stage because my tube amp accomplishes it.

Question: Is it typical of solid state amps to have less of a front to back sound stage than tube amps? Do they vary in this regard? Or, perhaps, am I failing to do something -- such as re-position my speakers? (After all, I immediately get that sound stage back when I switch amplifier without moving anything else.)

If you have any experience with solid state amplifiers and sound stage -- front to back, left to right, or whatever, I'm curious.

This is not about me keeping or not keeping the amp. There are many things I already really like about it. But I'm wondering about this aspect.

Thanks.

front to back depth has for me been more about speaker positioning than amplification.  
depth is only limited by how far from the wall you can pull the speakers into the room.  it is an excellent way to listen when your speakers are 5 feet from the wall or even more.  

stage height and width are more amplifier dependent.  i had a mid line solid state integrated and the stage was tiny, like a small window.  A-B' many times.  
my tube integrated and separates had the tallest, widest stage by far.  
tube preamp with good solid state amp is also nice.  
tubes rule by far, solid state sound stage size depends on quality of the amp.
