Preamplifier with Tube Line Stage HiFi Streaming & D/A Converter

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.

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 and is upgradeable making it future proof for additional formats.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 the A 3.2 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.

The beautiful RC 9 remote control with color display is available as an option. This programmable and rechargeable remote control always comes with a charging dock.

The AVM RC S App for iOS and Android devices will turn your smartphone or tablet into an easy-to-use remote control for your AVM audio components with integrated streaming capabilities and provides a variety of intuitive features to get the most out of your network-enabled AVM HiFi device.
