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.

A Carver C-1 preamp with BillD mod or a C-9 will make any system's soundstage wide and deep with sonic holography. 
Go buy a pair of tannoys If you want holographic...I use mine with class A solid state, sugden. However, I am also using a tubed phono stage, Tavish. I do not get a holographic sound stage with everything I play, however, It does happen often. 
What ought to be the minimum dBSPL speaker for a 7 watt 300B single ended amplifier please.
Thank you.

it was my gear for 15 years !...

What people name holographic impression exist...

The problem is the level of holography...

!0 or 25 % and the people say: i have holography...

But it is my experience and experiment with acoustic and psychoacoustic....

You need to controls vibrations of the speakers, electrical noise floor of the house and ESPECIALLY acoustic control not only material passive treatment...bUt the room with active Helmholtz resonators...

I am sorry for the bad news...

The good news is you have an idea of holographic with this pairing because the Tannoy dual concentric were even better than what i own now...

But what i have now is under acoustic control and give me more than the Tannoy even if it is a notch under their quality...

Acoustic is the most important tool in audio .....
MillerCarbon is correct, wait for the system to settle down and the new items to break in. After 300 hours you will have a good idea of what to expect for performance in the future. Patience
