What are the weak points of Pass amps and pre-amps ?

I have done thousands of tests in audio in over 20 years of time. I also compared many amps with each other. In stage depth, width and height the differences are huge.

A friend of mine had a concert room with a Steinway wing. I loved the intimate presentation of both voices and instruments during these concerts. It has become an important part of our Tru-Fi. Acoustic recordings need to give the same feeling.

With our Statement Audio Pro-measurement, we can come so much closer to the live experiences I had. It limits the influences of the room and gives access to a superior level in detail and layers of each recording.

Each part in any system owns it’s DNA. I did spend thousands of hours and tests in over 20 years of time to be able to reveal the full DNA of each individual part of an audio system. I have been working in audio full time over 20 years of time now.

Working by Tru-Fi you can create a superior level in realism and emotion compared to any trial&error created system. When we let new clients hear a Tru-Fi system, they understand often after a few sounds how limited their own system is.

The differences are created by the superior level in emotion. Emotion is the only key and way to success in audio. That is why an audio system needs to reveal all the details and layers of the recording. We always ask new clients to bring in their own music they know best.

Then it is very easy to feel and hear that Tru-Fi overrules their incomplete and limited trial&error system. The biggest problem in audio is that almost all brands and products cannot reveal all the aspects of sound. This means that these products will always create a lower level of emotion.

Only those systems who are able to reveal all the details and layers of a recording can create an emotional and addictive sound. Most people own incomplete audio systems with acoustic limitations. This will often keep them from buying new music each week.

In over 20 years of time, I visited hundreds of people with serious systems. I was often surprised by how little music they have. Trial&error will never make them understand what they change in their system. They focus a lot more on the sound and stage of their system. Trial&error will often limit people from listening to their music. The fact that they often have little music proves it.

Inna, I have a Pass Labs XA30.8 amp and a Pass Labs XP-20 preamp. They are great. The amp is a bit heavy 100 lbs, being class A it puts out a little heat. I don’t run my amp 24/7. 1 hr warmup is all that’s required for excellent sonics. I have no negatives for the Pass Labs XP-20. As with all equipment I would say ~ 500 hrs breakin to hear the “real deal”

I've never heard of Tru-Fi, is this a company, something you sell/rep work for?  Just never heard of it.

Tru-Fi stands for True Fidelity. You want to hear all your music as it sounds during the recording. Sound contains different aspects/properties. All different aspects of sound can even influence human emotion.

When you would read about how our emotion works regarding music you will find out that there are 3 aspects that influence our emotion during listening to music. We do a lot of research in sound all the time. As we use many modifications on amps, preamps, sources, power supplies and subwoofers. 

When you judge most audio products on the aspects/properties they can reveal it becomes very easy to understand what is missing and what can be heard. Most people do not understand why their system does not give them the emotional feeling they are looking for.

When you would know more about sound and how the human emotion works it becomes clear why most systems lack emotion. Diversity (lagering) in sound is the most important aspect of sound. Due to the fact that this part can create the biggest influence on our emotion during listening to your beloved music.

But when you would judge most digital sources and even amps these days on this part, the facts (the sound you can perceive) prove how limited the layering in sound is. When a system can only create a low or limited level in diversity in sound all human beings will not feel a lot of emotion during listening to their music.

When we let new clients hear their own beloved music with a Tru-Fi system, they feel and understand the huge difference in emotion. We use different songs to teach people what layering in sound is. And what it does to their emotion.

We use many different songs to explain the aspects which they miss in their system. We want all audio systems we create and adapt to be able to reveal all the aspects of sound. And what it does to all people is always the same. They use their system so much more frequently and longer at the same time ever before.

Tru-Fi proves on facts that it outperforms any created system by trial&error. It also proves that you need all the aspects of sound to be connected to the music. And experience the emotion the music possesses.
