AVM Audio OVATION SD 6.3 and SD 8.3 are high-end network preamps with streaming functions (AirPlay 2, Spotify Connect, Roon Ready, TIDAL, Qobuz, UPnP, Bluetooth 5.0), built-in DAC (Quad DAC 32 bit/384 kHz, DSD128 support), analog and digital inputs, as well as an amplifier for Class A headphones
A special feature of the EVOLUTION SPAS 5.3 is the built-in tube linear stage, which is located in the input section of the preamplifier. Equipped with lamps of its own production, specially made for AVM, it uses a completely new circuit for the latest EVOLUTION series, which was created by AVM Audio engineers, in order to fully unleash their tonal charm.
Enclosed in a classic format case, the preamp combines a switch of several signal sources, a universal phono corrector, a digital-to-analog converter and a Bluetooth 4.2 wireless module. On the back panel there are linear unbalanced and balanced inputs on RCA and XLR connectors, as well as an input for connecting a vinyl player.
