AVM - SD 8.3 - Streaming Preamplifier

The SD 8.3 and SD 6.3 at a glance

OVATION SD Streaming DAC – a completely different animal: The new SD  6.3 and SD 8.3 herald a completely new category of AVM components with streaming capabilities. Both components combine an analog pre-amplifier with 2 analog line inputs, DAC with DSD, streaming  lient, web radio and a high performance headphone amp, all into one unit. We call them Streaming DAC or short: SD.

Both flagship models are close relatives: In the SD 6.3 we focus on pure solid state technology in all amplifier stages, while the OVATION Tube Line Stage of the SD 8.3 creates a unique warm and natural sound reproduction. This is technology is compiled into an OVATION Line cabinet size well known from our modular PA 8.2 pre-amplifier.

Since these SD units may serve as full-blown pre-amplifiers, combining them with our power amps SA 6.3, SA 8.3 or MA 6.3 & 8.3 is a logical consequence. Furthermore the SD 6.3 and SD 8.3 may as well be combined with active speakers. With the new SD 6.3 and SD 8.3, so called computer audio comes to the OVATION Line. A completely new combination of analog pre-amplifier, streaming client, DAC with DSD and headphone amp creates a new category of digital sound center for listeners with a focus on digitally streamed music from different sources.

Two ESS 9018 K2M Sabre32 DACs per channel are being applied. This way even the digital domain the music signals are being processed in balanced mode. High precision clocks are being applied. The voltage regulators are separated for both DACs and the supply voltage is regulated twice. This decouples the DAC entirely from other parts of the digital circuitry. The AVM streaming engine allows countless formats to be processed and is upgradeable making it future proof for additional formats.
