In 16 years of time I have also tested many conditioners. Like amps, cables, speakers and sources there is more shit on the market than exeptional good stuff.
I use a powersource+. This conditioner is superior to any PS Audio product. It increases the dynamics, drive and all layers of the lowest freq. Even if you put cables like the Purist Audio Limited Edition to the conditioner, it works better than direct to the wahl.
The difference in the mid freq, are stunning. It has much more flavors and is more open in the mid freq.
In the high freq. there are more details and there is more decay. So you get a wider and deeper stage. I Always say: The right and left corner behind the speakers go deeper.
Another difference is the extra authority. ( less noise)
And the blacks are better as well so you get a more touchable image.
Last we week we compared interconnects from MIT and Audioquest. The silver interconnects from Audioquest are superior to all the copper MIT interconnects. Why?
Because silver gives you more resolution and a wider and deeper image compared to the copper interconnects. Silver is very important for the absolute sound. I have said this before. I had this discussion with a person who distributes Transparent overhere.
The individual focus of instruments and voices is superior with the Audioquest against the MIT. The New Wild Blue Yonder with there new improved plugs even let you hear the difference in hight of percussion. Going back to MIT, it is gone. And even the sharpness of the individual focus is inferior. The only small advantage of the copper is that the mid freq. are a little more involving.
