Atma-Sphere Class D getting some love


 Read all of it here

 

Moving on to electronics, in the Unique Home Audio room I found myself searching in vain for the big monoblocks that I assumed were responsible for the effortless sound emanating from the gorgeous Italian Gold Note speakers. (Other electronics were also Gold Note.) Failing to locate the amps, I asked where they were and was directed to a pair of tiny boxes squatting on the floor. These, I learned, were the new $5400/pr. Atma-Sphere Class D amplifiers. That’s right: a brand known for tube amplifiers has built a Class D unit. I must say, true to the manufacturer’s word, the amps had tube-like warmth and sweetness. But their 100-watt GaNFET output stage and 800:1 damping factor also produced thunderous bass and high-jumping dynamics. Highs were clean, extended, and never exaggerated.

Interesting to see how class d amplifier manufacturers are going with GaNFET output devices. Maybe there’s something to that.

Not all of them are NAD is purfi and Bel Canto is Nucore. I love my Bel Canto gear and was not crazy about the NAD gear I had.

I think a lot of it is what is done up stream from the core?

Ralph would no better but GaNFET seems to be the flavor of the month.

Really enjoyed my time in this room at the Florida Audio Expo.  Not familiar with the Goldnote Speakers presentation but the room was extremely enjoyable with a very balanced sound that I visited multiple times over my days at the show.  Congratulations Ralph!
