Mcintosh 452 vs Pass Labs XA 30.5


Hello everyone, I'm at the Mcintosh house and so maybe part of the answers will be taken for granted, thanks to the desire to try new devices I'm evaluating a transition from my current Final Pass Xa 30.5 to a MC452. Even the pre should be replaced by switching from an Xp10 Pass to the Mcintosh C48.
I use the Totem Mani 2, Audio Physic Scorpio 2 and Tannoy Eaton speakers in a listening environment of around 20 sqm at low and medium volumes.
I would like some advice from those who have had the opportunity to try, comparing these brands and the good interface between the coupled MC 48 and 452 and my speakers.
Thank you.

At the end it depends which properties your loudspeakers and other stuff of your system you own. But...when you would compare Pass Labs and Mcintosh together in a shootout with a system what can reveal all the different properties of sound. The Pass will be superior.

This is very easy to explain. The Pass can create in a perfect set-up a wider and deeper stage. This is alsway a possitive benefit to create a stunning 3D holographic stage.

And it is also better in timing compared to the Mcintosh. It is more controlled in the lowest frequencies. And you will be able to hear more layers in the lowest frequencies as well.

The other benefit you will hear is that the Pass creates more layers in sound. So it reveals a higher level in diversity of sound. This property is the most important one compared to all the other properties of sound.

Based on the fact that this one has the biggest influence on the human emotion. When you understand music and sound I can garnatee you that you will choose for Pass Labs. But people who have less experience and knowledge could easliy choose for Mcintosh
You need to read before you talk this nonsense. he wrote; the Pass blows  the Mcintosh out of the water. Not the other way around

A rich sound is totally different than layering in sound. Diversity in sound is what creates a higher level in emotion. A rich sound misses the diversity. And will always create an inferior level in emotion for each single human being. Based on the fact that our emotion works that way
I have done thousands of tests in  audio in almost  20 years of time. I know the differences very precise. Sound is founded on properties. These properties needs to be revealed by the audio system you need.

The Mcintosh will fill in all the different properties of sound less precise and convincing. Just compare a Pass and a Mcintosh at the same price level with loudspeakers, pre amp and source what can reval all the different properties of sound at a stunning level.

Then you will understand......
The Mcintosh owns what we call a pleasant sound. But I have done so much research in sound and the emotion of us humans. That I now know and understand that you need diversity in sound instead of a pleasant sound.

When you listen to your beloved music between an amp with a pleasant sound vs an amp which can reveal all the layers in the whole frequency range. You will choose for the last one. Based on the fact that this one will give you a more emotional experience.

This is how we do audio. We let people hear to what we call a Tru-Fi system. It reveals all the details and layers of a recording. When they bring their own music with them we can let them experience their own music in a Tru-Fi system.

The outcome is the same over and over again. They all experience their music at a superior level in emotion they ever auditioned. Music is emotion.

I have done so much research in almost 20 years of time and still spend a lot of time on research. I am addicted to music since I was a child. I did learn to be able to extract of each single part on of an audio system all the properties it can reveal. I can label each part with the DNA it owns.

This is why I understand why each system sounds and build the stage what I hear.
The 60.5 and 60.8 are not the best Pass products. A XA30.5 cannot be used for all loudspeakers. And cannot be compared by a X series amp or a Class a/b amp of Mcintosh.

You always need to compare similar products in the same price range. I owned the XP-20 as well. It is a good pre amp, but it is not a stunning one. This is what you need for each Pass power amps and monos.

When you judge audio at the highest level regarding an extreme 3D holographic stage and the best layering in sound. Pass is the only way to go. In my world Mcintish is not acceptable. Due to the fact that I have listened to so many products and I did compare many. A born perfectionist is only interested in the best result possible. 2nd best and less is in my world for all those born losers.
It has nothing to do with being arrogant. Audio is being founded on properties. These are the essential parts of audio. And they tell the truth.

It depends what you would like to hear? The truth or the thing you would like to hear. We choose for the first one.
hahahahahahaha......I have done thousands of tests. And I do audio full time for almost 20 years of time. We live in a different world. We are so much further in details and results.

There is a group of people who prefer to hear the things they would like to hear. They do not like to hear the truth.


@d2girls Your reactions here on Audiogon proof you want to say something to peoole you don't agree with.

When you create your system by trial and error you will never understand why the stage and souns is what you hear. You do it all pure on gambling. It proofs that you do it at the elvel of a child, Based on the fact thta there is no foundation.

So tell us what your foundation is to create your audio system. And what is your reference you found your decisions on?
We can proof it by facts. That is what we do. It is very easy to explain. We have many many clients in my whole country with Tru-Fi systems.

When a client is looking for something in a particular price range we send them to client who own stuff in the price range they are looking for.

So we advice tgem always to bring in their own music they know well. So they can listen to a Tru-Fi system with their own music. The results are always the same. 

They are often amazed how big the differences are in emotion and intensity. They understand that it is superior to what they own and what they auditoned in other shops.

Audio is shootout and comparing. We work totaaly different. We spend so much more time in both sound&vision. I am addicted to it since I was a child. I spend over 200 dollars on new music each month. We love to visit live concerts as well.

Tru-Fi brings people so much closer to the truth and how music sounds and is being displayed in space.

We create many new upgrades for our clients all the time. They can take a listen to many tools and modifications in their own system before they buy it.

It is always our goal to create a superior upgrade for a price no other company can give. I have many clients who in the past where doing audio by trial and error.

Many often got tired because they were not able to get the sound they were hoping for to find. Most of them use their system each single day. 

It is our focus to create a stunning level in sound and music for each single person. That is why we did research in many diefferent price levels. I want other people to have the same experience as my clients have.

So they can experience the real emotion their music possesses. I want people to learn something. That is why I want to use conservatorium students so people can learn and understand how sound and music works.


I see you use horn loudspeakers. I can garantee you when you would listen a lot to live music in small settings you would never buy horn loudspeakers. Based on the fact that it builds the stage a lot different than voices and instruments do in real.

A horn loudspeaker also owns his particular sound. Often people use warm sounding amps and tubes to colorize the sound of the loudspeaker.

You want an audio system sound as realistsic as possible. Like you want to create the same intimate stage and focus of voices and instruments.

When you would listen to live music regarding both voices and instruments they are very small and direct. But when you listen to most horn loudspeakers often they are projected out of proportion. The peopel who make these mistakes have no idea hwo big they are in real.

I often asked them on shows why the instruments and voices are that big? And I asled them also often do you know how big voices and instrumentd are in real?

Often the have no idea. Most audio systems are all based on pure gambling. When people think this is the best way to create an audio system, I think they have no idea what they are doing!
I sold Luxman in th past. It is a 2D amp on facts. Based on the fact that it can build almost no stage depth. We are not talking about a personal taste. But a fact what can easily be proven by audio.

When you are saying here on Audiogon that Luxman is better than Pass you make a big born fool of yourself. Luxman has an inferior level of diversity in sound. This again has nothing to do with personal taste.

But again can be proven by shootout. Maybe Audiogon is for amatures. But when I read this kind of nonsense, it need to be said.

Many people make the mistake that a pleasant and warm sound is the same as diversity in sound. But it is not. Layering in sound means you can hear all the different harmonics in sound.

We have proven many times to clients that what they thought was a divers sound proved to be a pleasant sound. When we did a shootout, they had to agree that the Tru-Fi system was superior in layering in sound.

The question is: what is the truth? The thing I love most in audio is that what you hear will always tell the truth. So people can hear it themselves so there is no dicussion anymore.

We humans will always choose for the sound and stage what creates the highest level in emotion and intensity. The emotion only can be found on the recording. An audio system cannot create emotion by it self.

But you need an audio system what is able to reveal all the details and layers of the recording. This is why when you create sound just by the properties it owns, it will always create a superior level in emotion and intensity.

We can proof it over and over again. Soon we will start with professional videos with Sony professional. I will film how people react on their trial and error system. And how they react on a Tru-Fi system.

Audio is shootout and comparing.
When people judge on products others own, we always see that it becomes personal. I talked a lot in the last few months with manufacturers and other people who also work in audio for a long time.

I said; audio needs parameters to make it more clear to people. And many agreed. Now people can say whatever they want to say. There is no control and there are no rules.

Many brands like to use the word higend. You need to understand what sound is and how music is being formed. That is why you need to understand what al the different properties are of sound.

Together they create how we experience music. For us it is very easy to show the difference between 2D and 3D audio. Like we compare audio systems with a low level in diversity to a system what can reveal a high level in diversity.

Only this way people can understand what the different properties of sound can do. And even how they react on our emotion. All different properties of sound can influence our emotion.

You can find a lot of great articles about the human emotion. Also there are enough articles how music works regrading our emotion. It will make you more understand how it really works.

I have done thousands of tests in audio in almost 20 years of time. We still do a lot of tests in audio. When we go to a client for an audio system. We take with us over 6000 euro on high tech measurements.

When we do vision again we take over 6000 euro in high tech calibration stuff. The great thing about the time we are living now, is that there are great tools to create a level what was not even possible 10 years ago.

When you do both sound&vision by their own properties it will bring you to a level you never experienced before. Most audio systems are incomplete on facts, This means that by shootout it is very easy to let people hear which properties are missing.

Each audio system what reveals less properties of sound will always create a lower level in emotion.
When you want to experience music at the highest level possible you need a system what can reveal all the details and properties of the recording. This has nothing to do with personal taste. We are talking about facts.

The Luxman cannot create a very deep stage, becaus the stage dna is 2D. You cannot change this part, not even by modification. The second limitation on facts is that it cannot create diversity in height. Even this is a property of sound.

We have proven in the last months to many different people that Tru-Fi outperforms any trial and error system owned by new clients. We ask them to take their own music with them.

We let them hear their music with a Tru-Fi system. And they all agreed that it is superior to their own system. And they all agree that the level in emotion and realims is of a different world. Most of them said that they never auditioned this level in emotion and realism.

When we install an audiosystem. We bring in for over 7000 dollar in hightech measurement tools. Most companies only bring in a few cheep tools. Trial and error is a very low level in creating any audiosystem . And we can proof on facts over and over again that it is inferior based on facts compared to any Tru-Fi system.

Because the facts proof that they miss essential parts of sound. And we proof that the level in emotion and realism is inferior to our Tru-Fi systems. Each single human being will always choose for each audiosystem what can reveal all the different properties of sound. Due to the fact that all different properties of sound can influence the human emotion.

That is why each audiosystem what can reveal all the details and properties of sound will be chosen by each individualk person. We have proven this in the last months many times.

The thing I love most rergarding audio is that the most convincing and emotional sound will be chosen bij each individualk person. Based on the fact that our emotin works the same way. The only thing that is personal is our taste in music.

But......sound contains of different properties. And you need them all to feel the emotion that the music possesses. The beiggest propblem in audio is that over 99% of all audioproducts are incomplete on facts. This means that they cannot reveal all the different properties of sound.

And what is missing will never be there. Each audiosystem what is incomplete will create a lower level in emotion and intensity for each human being. And we can proof this on facts what we have done many many times.


I know many people who work in  audio who have the same opinion as I have regarding horns. We will use people from the conservatorium to show people how instruments sounds in real. And we will show them how an audiosystem sound what can reveal all the different propertis of sound. 

Audio is all about music and how it sounds in real. So this is the best way to show people how things sound in real.
Real instruments played by people can proof that horns create both sound and the size of instruments a lot different than in reality. Comparing and using real music is the best way to make people understand how instruments sounds in real compared to audio brands and products.
@hugh_jahol; only by using these words proofs how weak you are. You just need to focus on the thread. You have the freedom to give your own opinion about this thread.

Stop making it personal, just wrote your thoughts and ideas about this issue. It is that simple
People don't like to read negative information about products they own. So it becomes personal. As you always can read in their reactions.

People need to learn to look further. At the end the sound and stage you hear will tell the truth. People prefer to hear the things they would like to hear. They even prefer it than hearing the truth.

We let people hear their music by Tru-Fi, so they can decide what they think of it. People will always choose and want that sound and stage what they prefer. That is the simplicity of audio what I love most.

On each recording you will find the details and all the different properties of sound. So you need a system what can reveal this. There is not even any discussion possible about this. But when you focus and listen to most audio products the truth proofs that they are incomplete. We are talking about facts and this has nothing to do with personal taste.

When I ask people how the human emotion works regarding music and audio they have no idea. This proofs again that they have no idea what they are doing making their choices. The great thing about the internet is that you can find and read many articles about the human emotion.

I can garantee you that this will make you understand music and audio a lot better than you know now. 
When I talk to people about audio they often talk about emotion. So I ask them a simple question. How does the human emotion works regarding music?

And they say; I have no idea. You were talking about emotion but you can not tell me why and how it effects our emotion? And again they say; No I can’t

You cannot use words and assumptions when in real you have no idea what it means and how it works.

When you want to understand things you need to learn how it works and this comes not by it self. You need to take time to find the right information about it. The internet can give you when you want to all this information.

Sound contains of different properties. This has nothing to do with personsal taste. We are talking about facts. There is enough information about music and about sound.

In over 20 years of time I did spend a lot of time in reading about many different aspects of both sound&music. As I phoned and talked a lot with different specialists in different parts regarding audio. And I did many tests to learn how it works.

Most people who have audio as a hobby or they work in this world as I do believe that they have a lot of knowledge about audio. But when I talk to them they cannot answer almost all the simple questions about audio. Beside this they agreed that most things they say are based on information they got from distributers. Most are just assumptions. And can easily be proven by sound that they are not even true.

Most people who love audio and who work in audio are running on very thin ice. Based on the fact that even the most simple things they don’t understand.

When you want to understand and guide audio you need to understand a lot before you can manage and guide it. I wrote it many times overhere and I will say it again.

When you all are listening to your system at home you are listening to all the different properties of each single part in your system, the acoustsic and other parts like smog, magnetism and high frequent noise who negatively influence the sound and stage.

This has nothing to do with a personal taste. We have a personal taste in music. But voices and instruments are build on different properties. Again we are talking about facts. You need all the different properties of sound to be able to hear the song of the recording the way it sounded when they recorded it.

When you just focus on brands and products it is very easy to proof and show that most brands and products cannot reveal all the different properties of sound. When you let people hear with their own music a system what can reveal all the aspects of sound we see how simple it is for them to understand why this is so much more attractive and emotional to listen at.

This has nothing to do with personal taste. All different properties of sound van influence our emotion. When we let people listen to a Tru-Fi system they agree all that it is a lot more exciting and emotional then their own system.

This can be founded on facts. Because the sytem can reveal all the details and different properties of sound. This has nothing to do with personal tatse as most of you believe. I believed it as well untill januari 2016. Untill a client said; you have proven and thought me that personal taste in sound does not excist. It took him over 1 hour to persuade me.

Based on assumption I thought that I was 100% sure that audio is based on a personal taste. But the music it self is what it is. And the emotion tou can experience is founded on all the different properties it owns.

Humans can experience sound and music in a 3D spectrum. But the most audio brands and products are only able to create a 2D stage. Agaain we are talking about facts. The sound and stage proofs what you hear and how it is being projected into a room.

My clients all understand how big the diffences are between 2D audio and 3D audio. Because they all came from 2D audio, as I came form 2D audiuo as well. When you hear live music and after time you learn what 3D sound is and how it works. This is what you want. Because it makes the experience of music so much more intense and emotional.

It is not natural and it even does not make sense when audio is displayed in a 2D stage, based on the fact that we humans can experience it in a 3D stage. When we let people experience their music between a 2D and 3D system we see that they all react the same way.

Again this can be explained. Due to the fact on how our hearing and emotion works regarding music and audio. Even this has nothing to do with personal taste because this can be explained on facts and how our emotion works.

People become very personal when they read things they do not like. I understand that, but you cannot runaway from facts and things which can be explained. When you want to get to a higher level in audio sometimes tou need to learn to do things differently. When you are not open for this, you will stay where you are right now.

At the end each human being prefers a more natural and emotional sound and stage. This is what we create and how we do both sound&vision. Maybe you hear things you do not like, just be a man and take a listen. After that you can judge yourself.

We want to use conservatorium students because live music did learn me a lot about music and sound. And that is why I want to use it so other people can experience the same as I did in the past. So they will understand it as well.






I auditioned them both many times. I did own different XA monos in the past. When I audition the Mcintosh with my own music I always miss depth and width regarding the stage. The diversity in sound with the Pass is a lot better. It reveals also moere layers in the middle frequencies.

You never will see a show where people can hear them both wiht the same amps, sources and cables? This is how silly audio is. At the end it is all about shootout. Most are only interested in their own stuff and will not allow you to compare them.

It would be so much better if they become a lot more open and honest to audio lovers. I wrote it many times when they want to they can imply parameters. But they will not do this. They want audio to staf as fague as possible. So people have no idea about sound and music. It becomes a lot more easy to sell what they want.

They don’t care about the truth and best quality. They only focus on how much money they can make. When they want to give the audio busienss a boast they need to stop with all those lies. And create better products for customers.
