We have our demo pair of Atma-Sphere Class D Monoblocks available.
Alan Taffel from the Absolute Sound that visited our room:
“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.”
From Manufacrurer:
Our Class D project has been in the works since 2017. Our goal was to expand on the positive attributes our existing amplifiers, which have been getting great reviews and awards in the high end press for the last 30 years. So we felt we were in a good position to know if the goal was achieved. The result is a solid state amp that has all the smoothness in the mids and highs that you expect from an excellent tube amp but with considerably lower distortion, output impedance and obviously higher efficiency. Like our other amps, this one has a very nice first watt!
The Class D is a monoblock design based on GaNFET output devices and accepts both single-ended and balanced inputs. The circuit is entirely our own design and manufacture- it does not use anyone else's modules. The power supply employs a toroidal power transformer and has over-current protection to keep the amplifier safe in case of a short at the speaker terminals.
