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.

@decooney Exactly.

@ speakermaster

Solid state amps do not play depth in the recording unless the recording has depth information but when you play a good recording they will have a lot of depth especially if your speakers are two or more feet out from the wall behind them.

Sorry to repeat myself, both in the OP and in the follow up posts I did, but I have stated that my comparison is very carefully limited to those recordings with depth information as demonstrated by tube amps.

@mahgister I've already stated that I've paid a lot of attention to the room. You're dissertating on your favorite topic and celebrating your (apparently effective) Rube Goldberg inventions, at length, and hopefully someone benefits. It does nothing for the question at issue in my OP, but whatever. You want to write a long post about what you know and what you do and how inexpensive but effective it is? Have at it.

I was answering to something i judged to be wrong FROM SOMEONE ELSE NOT FROM YOUR EGO....Is the threads here always for the one person asking something?
Many read these posts like me.... I dont speak about politic or race or rap here....Then why not use your philosophical bent to make remark at least with humor? especially because you cannot refrain to correct me....

And i dont think my experiment with what you called "a Rube Goldberg invention" in a gibe , and which is called in science a Helmhotlz resonator , is out of the subject matter, save if you think that the question you asked only interested you...

i dont know why, but you must perhaps begin to forget about a post that is not for you or then banned explicitly in your thread anything you judge out of matter or anyone you decide to hate...

I will post when i judge it necessary if i want to answer someone....in ANY thread...

I dont act inappropriately....

I dont think that a long post is a motive for hate ....

Say it with humor i will apologize....

Take my place and read your 4 or 5 warnings against me with the same false neutral tone in other threads...

Spare me FURTHER warning and call the moderator instead...

By the way this acoustic subject about NO COST Helmholtz resonators is very important and NO ONE, save me, explain it...I know that for you i am an idiot with cheap "rube goldberg" fad but i dont like to be insulted...Especially if i am right...

Go and look all thread...No one speak about that very important acoustical use the way it may be used...They sell acoustic panel but it is half the job.... And this is NOT MY OPINION, this is pure acoustic fact...


Then before " diplomatically" insulting my device which is not a KENJIT machine nor a Rube Goldberg one save for audio snobs with costly devices, but only a legit acoustic device, think 2 times...

I am also philosophically inclined , then dont be surprized if i speak about philosophy in some other threads and keep your warning.... You are not god here...

I think i prefer direct insult from someone instead of being "diplomatically" warned with words without humor and a "paternal" cold tone....Hate me in silence ...By the way i like Rube Goldberg but i really hate to be treated like a clown....

I understand why you speak but try to understand other perspective...You are not the center of the world and i am not the only one to hate here...

And try to refute my arguments in acoustic or other matter, instead of "warning" me....






@jjss49 Nothing forcing me to read it. Others can decide if my point was fair. I didn't post in haste or anger. Annoyance, yes, but not in anger.
it is not an "accident".... it is not the first "warning" from him.... with this time a "diplomatic" insult....


Annoyance, yes, but not in anger.
if you were annoyed for the first time and without insulting my device which is pure science, i would not had react and i will have apologize like i have already.... But i am not the only one at fault here....

i have the right to answer someone else than you in a post by the way......

Others can decide if my point was fair.

To decide others must know that you warned me on a regular basis....But an insult is a bit too much for my temper... Sorry...

I am not a children to warn nor a clown to warn.... And learn acoustic to know the difference between a Rube Goldberg machine and a no cost Helmholtz resonator...


And before reacting against me in each thread think about my description of the powerful control someone could use with them to tune all acoustic features..... Study to learn if i am RIGHT or WRONG.... Spare me your paternal insult....Instead refute my claims with acoustic laws....

i cannot apologize for being too enthusiast, save if someone dont insult me and ask with humor....And i keep the right to answer SOMEONE ELSE post  at any time ....Are we free?
