Mcintosh mc601 vs Pass Labs XA 100.8

So, I take it you don't recommend passive bi-amping? How about active bi-amping with an external crossover?

Audio is all about comparing and testing. To create an external crossover you need the right skills.

When you want more controle and drive I would advice a more powerfull amp.

I owned the XA30.5, XA60.5, XA100.5, X250.5 and now the X350.5. I use it with the Purist Audio Limited edition. What this powercable does is impressive. The difference between this powercable and a 500 dollar powercable is this big that even a Pass Labs worth twice the price will not create this endresult. Most people who have this a s a hobby often use a low % of the whole quality of an amp.

That is why I use blind auditions to make this clear. Audio is in my world about facts. The best endresults wins. This is the only thing that counts!

Ok, I got it now, more powerful stereo amp...

That's cool about that power cable. It must be something else!

I agree, it's all about results.

I have created my own way of Roomcorrection. This is da Bomb.
Because I can outperform many highend pre amp with ease. At
this moment a Onkyo PR-SC 5509 will be modified with highend
parts.

But we go a lot further then this. We do this as well. But
also the chips will be replaced and many electronic parts.

In a battle against the Audio research Ref5SE it became clear
how superior the Onkyo with my Pro roomcorrection was. I had
the Pass labs Xp-20 for over 2 years of time. But the 5509
with my pro outperfroms the XP-20 on all parts you judge it
for.

- so much more authorithy
- superior timing and speed
- superior blacks
- so much sharper individual focus of instruments and voices.
- a lot more details
- much more air
- superior articulation of voices
- the edge of a voice, with the Ref5SE, this parts was not
even there.
- so much deeper and wider the stage was.
- even in sound it was better.

This was even without the Modification. This modification is
quite extensive. It will be mind blowing inclusing the Pro
measurement.

I have but a lot of time to test and compare roomcorrection.
The way people use the roomcorrection they make a huge
mistake. I had to learn to do it differently. Because the
measure at wrong heights and places. In the beginning I did it
like they tell you. I noticed the limitation in the dynamics.
Then the testing started and it went to a level I never could
imagine. In the last weeks I had a few visits of people who
are in this business or have a highend set. Many said that
this is the best sound they ever experienced. There is so much
more authorithy and infomrtations. I never heard any set in
any shop or show ( I visited many in 17 years of time) with
the black level I have now. Many people are overwhelmed by the
sound. Ths difference between what they know is that big.

I can create a stunning sound even in a worse acoustic room.
Stealth low freq. is a part of the roomcorrection. This is the
roomcorrection of the subwoofer. I have created a level of
intgration most people never experienced. I said to my clients
and many people who work in audio who also visited me that
some people at Audiogon called me a lier. They had to lauch
and said;stealth low freq is here at your house, they never
heard it. For them it doens't exists.

You need the fastest subwoofers on the market to create it.
Then you get a level in sound to die for. I also use the best
cables on the market and they are a big part in the stunning
sound. The level of 3d sound in depth, width and height is
difficult to believe and understand.

I auditionend many sets of 500.000 euro +, but even did not
give me this level of perfection I have now at home.

Beside my consulting I want to do more shows. So I can proof
and demo this level in sound for many people as possible.
Audio is about facts and proof that it is the best and most
convincing sound. The endresult in sound says it all!

Ok, Bo, thanks for that. I found it interesting.
