That’s not true these days consensus is now part of science.

-----------------------------------------------------------------------------------

Not real science, though you might think so by the groupthink passing as science today. Science makes real progress by people taking contrarian views, taking on conventional wisdom

Example 1: Ask the person who put forward the hypothesis that bacteria cause stomach ulcers. No one believed him until he infected himself and then cured himself.

Example 2: quote from Nobel prize winning physicist Max Planck:

“A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.”

I too heard these amplifiers at the Tampa show.  When I entered the goldnote room I sat down in the sweetspot listened for a song a guy requested a few songs they didn't have and offered to let him hookup bluetooth.  He did and we listened to 4 different songs then he had to leave.  At the same time a different guy asked what the atmashere on the floor were?  I never even saw them.  The rep said they were the new class d amps and that's what we listened too.   I asked how much they were.  It shocked me because all of the class d I have heard I didn't like. ( I heard the agd twice at that show much the music wasn't in the the wheelhouse for me to make a determination of positive or negative. I stand neutral) it's the first atma-sphere product I have heard.  I really liked the sound because I couldn't tell that it was a class d amp.  I ended up ordering one.  Up until that day I never believed that class d had arrived.  I a have heard most of the major modules and a few smaller companies class d and although better than 20 years ago not good enough.  My brother, for years has been telling me that class d was the way to go.  But my ears hear the higher order distortions that I just don't like.   It's the issue I have with all of the solid state amps I have owned.  Although I don't have tubes I have heard many and prefer the sound of the dominant 2nd and 3rd order harmonics.  This class d fooled me.  Hopefully what I initially heard will remain true when I get it in my system.  My advice is if you get a chance to hear one you should even if you are not a fan of class d.

Many class D amps go at or over 300WPC at 8 ohm. I wonder why this model goes only to 100WPC.

I ask this question because, if I ever go for class D I will look for the power rating first and I will only consider 300WPC or more. I had ARC class D (T?) 150WPC amp before and it sound much weaker than my Plinius class A 125WPC amp.

will keep my A/AB amps for the foreseeable future.

enjoy......

I have owned several class D amps of 2-3+ times the power (including the EVS 1200, based on dual AS 1200 modules) of my LSA Voyager GaN 350, pushing Emerald Physics 3.4 open baffle @ ~ 97dB, but it has considerably more umph than any of them. So much for wpc. Time to replace inefficient speakers
