    Classé Audio launches Sigma Series

    Here is a straight copy from the press release that Classé released on September 10th.

    CEDIA Expo, Denver, Colorado—September 10, 2014—Classé has announced the availability of a new series of components called Sigma, featuring a 7.1 channel Surround Sound Preamp/Processor, called Sigma SSP and two amplifiers, the AMP2 and AMP5, rated at 2x200W and 5x200W into 8 ohms respectively.

    “High-end is about passion, discovery, experience and technical exploration. It’s not just who can make the most expensive things.” said Dave Nauber, President of Classé. “Making more affordable products that are truly high-end is a greater challenge, which is why there is a gap in the market between offerings from the mass-market CE companies and the high-end brands. We chose to exploit our cost advantage as part of the B&W Group to fill this void with some exceptional new products.”

    The Sigma SSP has been optimized as a high-performance stereo preamp/processor with video switching, multichannel processing and bass management included. Connections for USB and Ethernet streaming augment the basic HDMI, coax and optical digital inputs. Balanced and single-ended analog inputs, including an optional phono stage, make the Sigma SSP a truly versatile preamp/processor.

    According to Classé, the amplifier models are derived from their breakthrough Delta series CA-D200; a Class D topology that addresses the problem of dead-band-time—the time when both halves of the amplifier are off—once thought to be the Achilles’ heel of Class D designs. The Classé solution achieves an astonishingly low 3 nanosecond dead-band-time, dramatically lowering distortion and enabling numerous other design advantages. The result is said to be superbly musical sonic performance along with other class D benefits like small size, low heat dissipation and high efficiency.

    “Our goals in designing the Sigma series were to deliver true, high performance for the audiophile, offer versatile connectivity to accommodate a wide range of sources, bundle it with a host of performance-oriented features and package it in a compact and affordable chassis.” said Nauber. “We have done all that and more. With their efficient use of power, the Sigma series designs generate less heat and are more eco-friendly than other conventional designs.”

    The Classé Sigma series is available in October.

    Retail pricing:

    Sigma SSP - $5,000 USD
    AMP5 - $5,000 USD
    AMP2 - $3,500 USD

    Classé is a subsidiary of UK-based loudspeaker manufacturer Bowers & Wilkins.

    Really don't want to start of by saying something negative I am however skeptic about using the amplifier modules based on the Delta CA-D200's. They have a pretty limited bandwidth according to their own specs. They are listed as 10hz-20 Khz.
    Not something that really can take advantage of the extra bandwidth that high res have to offer. Really hope they offer more than a severe cut-off at 20Khz.

      Have you heard the CAD200? It's quite good. Well actually I really enjoyed listening to it for the few minutes I got to. Which surprised me as I wasn't sure I liked the idea of my understanding of how it worked.

      Also I didn't feel I was missing out on the frequencies I can't hear anyway. But that's a completely different argument

            However cannot help but wonder if Classe got the timing wrong. Who wants to buy a $5000 pre/processor that is not equipped with Dolby Atmos? And looking at the number of output jacks on the SSP there is no way they can do that without a major re-design..

            Oh and prices seems to be out - at least this is what I found on-line..

            "The Classé Sigma series is available in October, priced at $5,000 for Sigma SSP, $5,000 for AMP5 and $3,500 for AMP2."

              Yeah I wondered that too. Only one HDMI output which might put some off. Only balanced outputs for L/R which is a shame. Surely the centre should be worthy of the same treatment? Is the room EQ a simple PEQ? A mate of mine is interested in the Sigma series and none of this will put him off but I imagine him being in the minority.

              One thing I really don't understand about the Signa amps, as well as the CA-D200 is why they don't have a digital input. If they do ADC as soon as the signal enters the amp why have a DAC upstream? I suppose for HT use they would need to use HDMI or some proprietary connection for the high res protected formats which would complicate. It's maybe that the ADC/DAC in the amp is very transparent and therefore doesn't matter.
