Der SD 3.2 at a glance

EVOLUTION SD Streaming DAC – a completely different animal: The new SD units herald a completely new category of AVM components with streaming capabilities. The brand new SD components combine a DAC with DSD, Streaming Client, web radio, analog PreAmp with 2 analog line inputs and a high performance headphone amp all into one unit. We call them Streaming DAC or short: SD.

In the SD 3.2 we focus on pure solid state technology in all amplifier stages. This technology is compiled into a cabinet size well known from our CD 3.2 or the SA 3.2 stereo power amplifier. As SD 5.2 we add the additional Evolution tube line stage as it is being known from the CD 5.2 or the PA 5.2. This proprietary AVM Tube technology in combination with new ways to access digital data stream is compiled in a housing size equal the size of the CD 5.2 or a pair of Mono Power Amplifiers MA 3.2 S.

Since both SD units may serve as full-blown PreAmps, combining them with our Power Amps SA 3.2 or MA 3.2 S is a logical consequence. Furthermore the SD 3.2 and SD 5.2 may as well be combined with active speakers. The two new SD Evolution Line components are close relatives and since there are many similarities especially in the daily operation and connectivity, we have chosen to combine both units into one product information. We will clearly mark which features differ or are reserved for the SD 5.2.

The SD 5.2 features the additional Evolution Tube Line Stage with two additional power supplies. These additional power supplies supply the tube heating. As tubes AVM uses the custom made AVM 83 T:
• Tube Line Stage with AVM 83 T used in balanced mode
• High voltage generator independent from the AC mains supplying the tube heating

With the new SD units so called computer audio comes to the Evolution Line. A completely new combination of streaming client, DAC with DSD, analog preamplifier and headphone amp creates a new category of digital sound center for listens with a focus on digitally streamed music from different sources. In the SD 5.2 the Evolution Line tube line stages are added on top, creating a digital music center with charming tube sound.

2 DACs per channel are being applied. This way even the digital domain the music signals are being processed in balanced mode. The streaming engine allows countless formats to be processed. Sonically, the SD 5.2 sparks the charming sound of the tube line stages. These amplifier stages are directly derived from the PA 8 of the OVATION Series enchanting with their emotional music reproduction. In the SD 5.2 tube stages the proprietary AVM 83 T tubes are being applied. The SD 3.2 derives it’s sonic diversity by using solid state amplification in all stages.

Like all AVM hi-fi components, both the SD 3.2 and SD 5.2 is carefully developed and assembled by our engineers in Malsch, Germany. Our vendors for housing and electronic parts reside all near-by. This proximity helps us to easily ensure and maintain superb quality level of the supplied parts for the AVM hi-fi components made of these. During the manufacturing process we perform repeatedly numerous tests to insure the absolute quality of our products. When the assembling is finished and the first inspection is done all units must pass a run in test in order to prove their reliability. After that a careful final inspection follows before packing & shipping. All this ensures creating a perfect product from AVM for our customers.
