The imaging is from added harmonics. Our ears are very good at locating the source of sounds above 6000 Hz because the head blocks sounds from one side of the head to the other - as much as 10dB for as little as 30 degrees off center. So a little added higher harmonics tells us where things are in the soundstage without affecting the timbre by much. The added harmonics also create warmth (the fundamental is richer or thicker or more solid sounding).
Natural binaural spatial cues that we hear in real life outside of stereophonic "imaging" are Interaural Level Difference (ILD) created by head shadow and the shape and orientation of the outer ears, and Interaural Time Difference (ITD) created by the distance between left and right ears and the different distance sound has to travel to left and right ears. The distance between ears is to small to create significant Interaural Level Difference. Interaural Time Difference dominates "imaging" (localization) below about 700Hz where the head is acoustically small compared to sound wavelengths so there is very little Interaural Level Difference. Interaural Level Difference dominates "imaging" above about 1,500Hz. Stereo channel level and time differences rendered by the natural spatial cues that locate speakers do not replicate natural spatial cues that locate singers and musical instruments heard in real life. Natural spatial cues that locate left and right speakers limit stereophonic "imaging" to the space between left and right speakers. No stereo channel level or time differences can create a convincing realistic stable phantom stereophonic illusion heard from a direction to the left of the left speaker or to the right of the right speaker or behind, above, or below the listener. Stereophonic "imaging" is created at the listener's ears, not between the speakers or in the listening room. Devices that provide identical, independent audio signal paths do not create stereo channel level and time differences required for stereophonic "imaging". Anything added by the amplifier that was not present in the sound before it was picked up by microphones is distortion. Most stereo recordings are made with monophonic microphones. Stereo channel level differences are created by microphone mixing console level controls.
@@paulsebring6930 I totally agree with the science quotes. You are quite right in your descriptions of ILD and ITD. Since we know that added harmonics from a tube amplifier will add sounds at higher frequencies it is logical to assume that this can contribute to better inter aural level difference (ILD) and this is precisely how tubes can improve imaging between the speakers. Tubes also help intelligibility of sounds as harmonics strengthen audibility of the fundamental - this can be a key benefit in Rock where mid range can be busy and loud. The Beatles found that Vox tube amp distortion (harmonics) made their guitars audible above screaming audiences. Tubes have their place as any guitarist can explain even though technically tubes tend to add more distortion than SS.
This is the best explanation I have heard you give by far with regard to today’s topic. It makes it very clear for me and possibly a whole lot of other people to finally get what you’re driving at.
That tube is so musical it was still dancing after being plugged in. Regarding output, I seem to recall tubes can endure a bit more stress than your typical output transistor parked in a heatsink.
Paul, I now own a Schumann Resonance Generator that came with 3 PSVane 6J1 tubes. I use silver power cabling and silver connector (2.5mm) cabling between the Zone Zero linear supply unit and generator. I was previously using a cheap 20w version that unfortunately was giving me headaches. However it worked but didn’t work anywhere as well as my current generator is working. On its second day, sound has never sounded so holographic. And no perceived headaches. I hope you can give this a shot.
The magic in my experience comes with a good single ended directly heated triode power amplifier. I find vocals in particular sound more 'in the room' and I believe it's due to second harmonic distortion plus a very simple minimum component signal path. My experience is with a Border Patrol SE300b amplifier.
@@alexanderstefanov6474 Not to shock you, but all your music has gone through a lot of transistors already, so whatever you hear is mostly conducted through transistors. Adding one tube in the path is not changing that fact. But tubes can do some magic in terms of musical distortion that is nice sounding.
My thoughts. Most of the questions posed to Paul(and I would add most of the innumerable RUclips audio videos) is that there is a focus on doing ONE particular thing which will create some audible change which is pre-ordained by only that change. IMHO,any change in the entire music reproduction chain will affect a change. The problem is the question ofmaking any change which will guarantee one desired effect. I don’t think that is possible.

Back in the 1990s, there are already solid state gear that exell in the holographic imaging department. To my ears, tubes excell if you want your Megadeth or Metallica albums sound as good as a Mozart string quartet and / or your musical preferences span such disparate genres.

My former preamp an audible illusions modulus 3B was just such a preamp. This is not the first time I made reference to the fact that I miss it but not enough to go back to it. For me, I wish that there were An FET based preamp that could add a bit of extra life to the music that is no longer present. But I have gained the ability to hear deeper into the music with my new preamp and I have a lower noise floor among other positive attributes.
I agree! I acquired an el-cheapo ebay tube pre-amp kit recently, replaced the chi-fi tubes with NOS General Electric tubes and I could hear/feel a difference immediately even with my moderate mainstream gear! BTW, a stock naturally aspirated Subaru is pretty sluggish in general, so your observation isnt very far off!
I have no doubt the Stellar phono amp is better than my little Tavish tube-based phono stage. BUT it costs multiple times more, and quite frankly the Tavish is really, REALLY good. But in regard to tube rolling, absolutely yes, that is a huge advantage. I’ve pretty much settled on a valve complement for my little ‘flea watt’ integrated amp. I’ve swapped out every tube and more than once. All made a difference, but perhaps the biggest was the rectifier - I’m now running a vintage (early 50s?) Sylvania Type 80 which is noticeably better and kicks the butt of the rectifier that shipped with the amp.
It depends on the exact circuit design, the characteristics of passive parts, and several other factors.

Everyone seems to endow vacuum tubes with magical properties they do not possess. They are electronic devices, like transistors, and can be good or bad depending of the circuit they are in. Having said this, the last solid state preamp I owned was back in the '90's, a Parasound as a matter of fact. Parasound makes good stuff. Adding more stuff will not make it better.

Specs were lousy, 40hz-15khz, acoustic suspension--needed at least 20 watts, beautifully constructed, and expensive, $1,800 in 1995. About $2,200 if you bought the matching stands. I own a pair of these, paid $200 for them, and the image is there no matter what I drive them with. No else has ever done this before or since. The closest thing I can think of now would be a KEF LS-50, a speaker I have not heard, but it gets lots of raves.
Could this 3D/holographic imaging have more to with the input, interstage, and output transformers? Or even inductors in these circuits? Phase shift & electromagnetic crosstalk (in the subtle addition harmonics imparted by these types of components) certainly can participate in the holographic sound, no? But as you wrapped up the speaker placement and room certainly make up most of the 3D image (at least in what I’ve experienced).
Most recently recorded music has gone through a handful of 5532 Op-amps (in series) long before it reaches ANY tube. The 7293 (50 Watt) chip-amp has a holographic sound stage that rivals most discrete transistor amps. The (theoretical) reason is that the internal components are perfectly matched and never drift.

Lol. Audio to Subaru. It does rhyme though. Well I owned a Subaru Baja which was really based on one of their SUV. It had a turbo. The performance was fantastic both in terms of performance;speed =turbo and driving in snow and rain. But the maintenance was a never ending cash drain. The turbo blew on it. The valves/gasket/engine mount all fell apart. I had to junk at 150,000 miles because the cost of repairing was greater than it was worth. As I did research I found out that Subaru’s had many quality issues. I don’t know if they have been fixed but right now I would be able to recommend a Subaru. The most expensive car I ever owned.
Tubes baby...For the $$'s...2021 Stereophile Class A recommended Sunvalley SV-EQ1616D Tube Phono Equalizer. Agree with Paul "Holographic Imaging" is in the Chain of Gear used.
I have a chinese tube preamp (buffer) most of people like to think they use fake tubes or they are only for "show off" but for me is the only cheap way to add that sweetness and holographic sounding to bad Hi Fi sound sistems like Yamaha, Onkyo, Sony Etc..
Comparing to jFETs, tubes give 6dB to noise in a phono preamp (because of 200-300F temperature), and have a terrible microphonic effect. And by the way, Douglas Self proved that NE5532 is the most optimal opamp in terms of signal/noise ratio, and of course it's better that your TL071. So, I'm confident that there is no need to use tubes in a phono preamp. Besides, with jFETs it's easy to use batteries. But if we talk about a linear pre-amplifier, electrostatic headphones amplifier, or sometimes about a power amplifier (push/pull, ultra linear or triode mode, except one for a sub-woofer, where I'd like to find a G class amp), then well... tubes allow to create the shortest signal path. And I would swap them only for Luxman, Accuphase, or similar.
I’d rather stay with the basic tube circuits. I’ve tried DSP with the roon parametric equalizer and the first judicious amount of correction sounded better but it’s addicting and by the time I got finished making adjustments it was horrible. Put a tube preamp into a circuit and you get a small dose of second harmonic distortion which is euphonic.
@@Scopolamine46 I was just speaking to the term "holographic." I can make things sound like they are coming from the side wall with just 2 speakers or create a 3D image in front of you. But also DSP can imitate any tube ever known to man. But I think people simply enjoy playing with tubes, which is understandable and cool.
The Svetlana 6922 preamp tubes in my system has been installed there since 1995 and still registeres OK on a monthly tube tester test despite being on for an average of 4 hours per day excluding the odd vacation or two.
But.... a "holographic" soundstage is generally recognized as a strong point for tubes. They do it by nature. Just as by nature they produce a fair amount of distortion.

Do you not need to use gloves when handling tubes? I have to use gloves when handling the flash tubes for my photography lights to keep my oils from getting on the glass and shortening the lifespan of the bulb. Just curious
Those photography lights are using halogen bulbs, which run extremely hot(like white hot) and oils from skin can cause them to fail prematurely. Vacuum tubes/valves don't run like that, and they might only be warm to the touch, I've never used gloves when handling them.
"There you go"......as the tube is wobbling like a weeble wobble and clearly not even in the socket. Next time make sure we can't see the top of the tube Paul, Haha!
I've got a tube buffer that I have tried between the preamp & the power amps & I just think it degrades the sound quality.It can also be used as a preamp but again really poor quality. Not at all convinced.
@@graxjpg 1. Needed to amplify the signal from 2 to 10 times. Average of 3 times amplification 2. Remove common mode distortion 3. Add low pass filtering 4. Make sure there is no DC present 5. Buffer any analogue volume stage 6. Provide sufficiently linear performance. 7. Provide for balanced or single ended output 8. Provide current capabilities to drive long interconnect. 9. Mute the output of any startup pops or noise. (source PS Audio website)
Well, John, I would argue for a little bit of poetic leeway when using the term. Of course a hologram is specific to light but in this case, we're using it to describe a recreating three dimensional image of sound which, when you hear it, justifies the word hologram. In a metaphorical sense.
Anybody else noticed that Paul did not install the tube back properly?! :)
Otherwise the video would have gotten too long 😉
When he let go, that tube wobbled like a Weeble! XD

He's not going to refer to VFets I suppose. Tube sound, Transistor reliability and gain. Yum !
Tubes have a more linear frequency response suitable for preamps.
tubes are very strange story,take a ecc82 for example,it is not the most linear tube but a few better tubes in theory have so open and musical sound
What tube brand do you use .... 12ax7 ... ?????
Why do u have a problem with Subaru’s ?
A COOL little tube? Not when operated!
Thanks Paul now that vintage is the new trend gonna get My Eico all tube pre out of the closet
tubes degrades as lightbulbs, how often do i need to exchange the tubes, ? one times per year ?
no tubes have long time life,change only if you hear the sound more "bloom",i had my telefunken tubes more than 4.000 ouhrs
The Svetlana 6922 preamp tubes in my system has been installed there since 1995 and still registeres OK on a monthly tube tester test despite being on for an average of 4 hours per day excluding the odd vacation or two.
Most of the tubes in my Lowrey are from 1959. Tubes don't "degrade as lightbulbs". I've got good tubes from the 30s.
Of course if you install a tube in a circuit that it wasn't designed for, it's going to do different things.
But.... a "holographic" soundstage is generally recognized as a strong point for tubes. They do it by nature. Just as by nature they produce a fair amount of distortion.
'And it is also said,' answered Frodo: 'Go not to the Elves for council, for they will say both no and yes.'
'Is it indeed?', laughed Gildor. -- J. R. R. Tolkien (1954)
'Twas in the darkest depth of Mordor, I met a girl so fair
But Gollum the Evil One crept up and slipped away with her, her, her, yeah... - Led Zeppelin (1969)
The light cast by tubes are great at creating shadows thus may be good for 3D lighting.
Tube rolling is a simplified variant of switching between DSP presets.
You can roll op-amps and get just as many differences in sound.
@@andershammer9307 Yep. Even my desktop PC has that feature.
don't forget to mount that tube back in properly..
Do you not need to use gloves when handling tubes? I have to use gloves when handling the flash tubes for my photography lights to keep my oils from getting on the glass and shortening the lifespan of the bulb. Just curious
Those photography lights are using halogen bulbs, which run extremely hot(like white hot) and oils from skin can cause them to fail prematurely. Vacuum tubes/valves don't run like that, and they might only be warm to the touch, I've never used gloves when handling them.
@@michaelturner4457 Got it. Thanks. Was just curious because I have to handle my halogen bulbs with gloves when I replace them.
Being obsessive compulsive as I am and reading in certain operations manual’s that are for tube components I would say yes, wear cotton gloves.
Holographic imaging is more pronounced when the tubes are in the amp stage instead of the preamp.
So true.👍
thx paul
I am afraid that if I got into tube gear that I would be obsessed with listening to the tubes sound then the actual music. LoL
I had tubes and all I could think about is when they'd go out.
Good tube amp kick ass every transistor.
Holographic imaging of a pair of stereo speakers is only possible through crosstalk cancellation.
"There you go"......as the tube is wobbling like a weeble wobble and clearly not even in the socket. Next time make sure we can't see the top of the tube Paul, Haha!
Paul please stop dissing tube power amplifiers at every opportunity, good ones kick solid-state all over the listening room.
That tube doesn't look like it's in there very good! 😀
That thing was rocking!!
Look at those cute speaker on the wall, ok im not going to buy any PS audio thingy if those are your reference speakers for measurements HAHAHA :P
Don't buy that preamp Paul was working on.
Why do CEOs muck up things like trying to attempt installing something like a tube in its socket?
I've got a tube buffer that I have tried between the preamp & the power amps & I just think it degrades the sound quality.It can also be used as a preamp but again really poor quality. Not at all convinced.
Boy a tube DAC would be great about now!
That’d be silly, the analog output stage of the dac does not need to be amplified
@@graxjpg
1. Needed to amplify the signal from 2 to 10 times. Average of 3 times amplification
2. Remove common mode distortion
3. Add low pass filtering
4. Make sure there is no DC present
5. Buffer any analogue volume stage
6. Provide sufficiently linear performance.
7. Provide for balanced or single ended output
8. Provide current capabilities to drive long interconnect.
9. Mute the output of any startup pops or noise.
(source PS Audio website)
Just put a distortion pedal after your DAC.
@@drdelewded put the DAC though a Marshall amp for all the sweet tubey harmonics
@@graxjpg plus eq and reverb
you just broke the tube
No he didn’t
I just watched a video from Audio Science Review about Grounding and it was full of mistakes and myths!!
holographic? that is a total mis-use of the term;
Well, John, I would argue for a little bit of poetic leeway when using the term. Of course a hologram is specific to light but in this case, we're using it to describe a recreating three dimensional image of sound which, when you hear it, justifies the word hologram. In a metaphorical sense.
Yet another shameless plug,valves are better they can even dance the hippie hippie shake 😂😂😂
"holographic imagining"??? 🤔
I'm guessing lasers would be more effective.
