Classe introduced its new Sigma line at the show, consisting of the Sigma SSP surround sound preamp processor and two amps, the 5-channel Amp5 and the 2-channel Amp2. The latter are both compact class D designs offering 200W per channel into 8 ohms and 400W per channel into 4 ohms.
The Sigma SSP, shown in the photo (though it looks far, um, classier in real life than my middling photography might indicate. It is loaded with features, including SPDIF and 24-bit asynchronous USB digital inputs, DSP-produced parametric EQ and tone control on all channels, and all of the other modes and features of any competent pre-pro. But it has only one HDMI output, is only HDMI 1.4, and is not yet Dolby Atmos-ready. But it's modular design should make future Hardware updates possible. The Sigma SSP and Amp5 are $5000 each, and the Amp 2 is $3500. All three should be available by the end of the year.
