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.

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.

His posts are unreadable in my opinion. If I’m reading a thread and I see he has posted I just scroll past him. He just keeps repeating himself over and over. Hey Bo, you need to come up with some new material.
My last post was deleted, it’s ok I understand why.

To make it a short story, I own a Luxman M900u and the pre I use is a McIntosh C52. I did the preamplifier acid test. I compared the DAC direct to amplifier VS DAC to C52 to amp. to see if I was loosing on resolution and harmonic layering.

The answer, the C52 is transparent as clear water. I was astonished, I did not feel the need to buy the C900u from Luxman, as I was earing every sonic nuances with Mac...

As usual the preamplifier eliminates the thinness of dac direct to amp, elevates dynamics , creates a bigger soundstage, we all know that this is a fact when the dac output stage has not enough voltage to drive the amplifier.

Now about PassLabs , very good gear, but sorry the Luxman M900u has craftsmanship never seen in any Pass gear. Like comparing a Corvette ZR1 to a Bentley...
