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.

Between the complete absence of detph imaging and holographic detph imaging filling the room there is many levels of manifestation for this acoustic quality...


Some amplifier are better than others to create it.... This was explained very well by atmasphere posts...

But without acoustic control of the room you cannot hope for the maximal manifestation of this quality in a room....In most of the case for sure...

And again -- so many words. I am not replying anymore to histrionics.
who are you?

you just insult me another time...

it is amusing?

I prefer to be "histrionic" than being like you act....

There is no rule here about the number of words in a post but there is rule about insults....

Study acoustic instead of calling me name and dont upgrade your amplifier without doing it... 

Histrionic advice...

From my OP:

the amp produces a sound stage that is nicely defined and articulate from left to right, but not as much from front to back.I know my room is capable of that sound stage because my tube amp accomplishes it.
See where I said, "my tube amp accomplishes it"? What does "it" mean? Well, that is precisely the point where I told everyone that the room has acoustic control over sound stage, including depth. This is why it is redundant and unnecessary to explain (again and again) why it is important to exercise acoustic control. Got that covered. In the OP. And in my comments. Again and again. Now I am really really done making this point.

Then it is the amplifier...

case closed...

In general, and in my experience, solid state does depth great. Tubes do too, but overall, I do find that tube amps give a bigger sound stage all around, particularly scale of artists and in sound stage width. That said, I am sure there are varying degrees from different solid state vs. tube amps depending on design.
