Holographic Soundstage ?

I would like to share my observation and hopefully get some input from people who have the same interest.

My system consist of Wharfedale Opus 3 , Krell KRC-3 preamp, Krell KSA 150 amp, Chord Qutest DAC and a computer with JCAT USB EX running Roon/with LPSU from HDPlex.
I mainly like holographic soundstage and would be able to achieve a very good 3D soundstaging with my current Krell setup.
I decided to try out tube amp a couple days ago because I read through the internet and everybody told me that tube amp always have better holographic soundstage and 3D imaging comparing to SS amp.
So I order a Raven Blackhawk MK3 from Raven audio with 45 days home trial just to try it out. I was expecting a very holographic soundstage that will blow my Krell out of the water.
Well, I was so WRONG. The Krell combo actually has a deeper and wider soundstage comparing to the Raven.
The Raven also has some very weak bass comparing to the Krell which is more punchy and tonally rich textured bass.
I cannot understand why it happens. I am always under the impression that tube amp will always provide more holographic soundstage. Obviously, In my set up the Krell is superior when it come to 3 dimensionality.

I will keeping trying out the Raven Blackhawk in the next couple of weeks and if things are not improved. I am ready to return the Raven and perhaps trying out the other tube amps (or solid state amps) that can beat the Krell combo.

If any one has some idea of such a product, please let me know. I am looking for an upgrade right now.

Best 3d sound i heard was after hours at a Chicago emporium that had a Art Audio 845 SET. Integrated (Diablo)? driving a single horn Zingalli loudpeaker playing Duke Ellington on vinyl through a Px Art Audio phonostage, SPOOKY REAL!
I felt as if id gone back in time and was looking down from a balcony upon the performers.

I just relate this 2002 experiance as testimony to the importance of proper speaker and amplifier pairings for desired effects or results.
In class A its also important to have a stable 8 ohm impedance to get the best results even with solid state class A.
Ita all about removing the noisefloor.

I hope im not distracting from origionl post as my experiance or testimony as it relates to his desires is my best way imo to be of help.

In my experience the room's acoustics is perhaps the most important factor in soundstage imaging.  Side wall reflections can muddy an image as can sound waves coming from the rear wall and front corners.. Before I chased different equipment I'd tame the beast that your system lives in

exactly right...

Save the early and late reflections must be tamed not necessarily erased,but advanced or absorbed or retarded , they must be synchronized, then absorbing methods are relative to each situation and need to be experienced.... In my case i control all acoustic factors with also a controls of reflections from side and back.....We play with milliseconds factors here detectable by the listenings experiments...

Back reflections will play a positive role in listener envelopment factor this is demonstrated... All is a quesion of balance and timing thresholds....

Acoustic is not most think it is like buying costly materials and think they are done because the sound is good....

If you have not a room 3-d filled with sound NOT coming from spealers but an holographic volume encompassing and even including you in many recordings, you are not done.... And at the end instrument and voices timbre must sound natural ....
